SharePoint vs. OneDrive vs. Teams: Differences, Connections, and Why Everything Ultimately Runs Through SharePoint<\/h1><\/div><\/div><\/div><\/div><\/div>SharePoint, Teams, and OneDrive have long been part of everyday work life in many companies. We save our own drafts in OneDrive, collaborate with our department on a SharePoint project, and coordinate with each other in a Teams chat on the side. Three applications that seem to do the same thing but differ in important details. Surprisingly often, it remains unclear where an uploaded file actually ends up, who can access it, and what happens when a colleague leaves the company.<\/p>\n
This uncertainty is not a sign of ignorance, but stems from the architecture of Microsoft 365 itself. The three services are not separate tools, but closely integrated building blocks that are built on the same foundation behind the scenes. Once you understand how they work together, you\u2019ll share files more securely, assign permissions more thoughtfully, and navigate the entire Microsoft 365 ecosystem much more easily.<\/p>\n<\/div>

<\/span><\/div><\/div><\/div>Three Services, One Common Foundation<\/h2><\/h2><\/div>The most important point to start with is this: In the end, almost every path leads through SharePoint. Microsoft 365 combines three services\u2014SharePoint, OneDrive, and Teams\u2014for document storage, personal storage, and communication. Because they are constantly used together in everyday work, it\u2019s easy to get the impression that they perform similar tasks. In fact, however, each service plays its own distinct role, and two of them are technically built on top of the third.<\/p>\n
SharePoint is the platform for collaborating on documents and projects. At its core, OneDrive is nothing more than a private SharePoint site and serves as personal storage. And Teams uses SharePoint and OneDrive in the background for long-term file storage instead of maintaining its own repositories. At first glance, this relationship may sound like technical nitpicking, but it has very practical implications for who can access which content and for how long.<\/p>\n<\/div>
<\/i><\/div>Microsoft SharePoint: The Foundation for Collaboration<\/h3><\/div><\/div>\nWhen multiple people collaborate on documents, projects, or information, SharePoint usually comes into play in Microsoft 365. The web-based platform has been part of the Microsoft portfolio since 2001 and serves as a central repository for the structured management of content within an organization. You can think of it as a company\u2019s shared file repository\u2014only in the cloud and with far more features.<\/p>\n
SharePoint is built around what are called “sites.” A site is a self-contained area that can contain document libraries, lists, pages, and other information, similar to a website with multiple subpages. Access to this content is typically restricted to specific users or groups. Behind the scenes, this access is managed through users and groups in Microsoft Entra ID, Microsoft\u2019s cloud-based directory service, which was known as Azure Active Directory until 2023.<\/p>\n
It\u2019s also important to know that SharePoint comes in two forms: as an on-premises server version (SharePoint Server) that runs in your own data center, and as a cloud service, SharePoint Online, within Microsoft 365. The online version is much more widely used today because it allows companies to outsource the costs of hardware and maintenance. In both cases, SharePoint serves as the technical foundation for many other services, including OneDrive and Teams. Typical use cases range from company-wide intranets and internal wikis to project sites where multiple departments collaboratively manage documents, spreadsheets, and schedules.<\/p>\n<\/div><\/div><\/div>
<\/i><\/div>Microsoft OneDrive: The Personal Storage Service That's Actually SharePoint<\/h3><\/div><\/div>\nWhile SharePoint is designed for team collaboration, OneDrive serves primarily as a personal storage space. Every licensed user is provided with their own cloud storage (typically 1 terabyte) and can store, edit, and organize documents across any device. By default, only the owner has access initially; however, files can be shared with colleagues or external partners at any time.<\/p>\n
From a technical standpoint, OneDrive is also a SharePoint site\u2014albeit a private one that only the owner can access. You can therefore think of OneDrive as a personal version of SharePoint, tailored for individual document management. The service\u2019s greatest strength is its tight integration with Windows Explorer, which leads many users to perceive OneDrive as part of the operating system rather than as a separate application.<\/p>\n
However, it is precisely this association with a specific user that presents a common pitfall. If an employee leaves the company, access to their OneDrive content may be lost. This depends on how the tenant is configured and which retention policies apply. Microsoft generally does not delete the data immediately, but in practice, supposedly important documents frequently disappear because they were stored in a colleague\u2019s OneDrive instead of in a shared location. In addition, the version history in OneDrive is limited by default and also depends on the tenant\u2019s retention policies. The lesson here: Anything the team needs long-term belongs in SharePoint, not in a personal OneDrive.<\/p>\n<\/div><\/div><\/div>
<\/i><\/div>Microsoft Teams: The Interface That Brings Everything Together<\/h3><\/div><\/div>\nFor many users, Microsoft Teams is the central entry point to Microsoft 365. Chats, meetings, video conferences, shared files, and entire projects all come together here in one place. The primary organizational level consists of the \u201cteams\u201d that give the platform its name, where fixed groups such as departments, locations, or project teams coordinate their work. A person can be a member of multiple teams, and additional tabs allow users to integrate calendars, tasks, spreadsheets, or reports.<\/p>\n
The key point is this: Teams uses SharePoint and OneDrive for long-term file storage. Instead of maintaining its own storage, the application relies on existing Microsoft 365 services in the background. When you create a new team, Microsoft automatically creates an associated SharePoint site. All files uploaded or shared in a channel end up there. Teams is therefore less of a storage location and more of a convenient interface that brings communication and documents together in the right context.<\/p>\n
The situation is different for files sent in private chats or group chats. Teams first copies these files to the sender\u2019s OneDrive and then makes them available to the respective chat participants. This has an important implication: Files from conversations remain accessible only as long as the sender\u2019s OneDrive account is active, unlike content shared at the team level in SharePoint. Anyone familiar with this difference will immediately understand why a file is sometimes permanently available and other times disappears along with a colleague.<\/p>\n<\/div><\/div><\/div>
<\/div><\/div><\/div><\/div><\/div><\/div>Where does each file go? The simple rule of thumb<\/h2><\/h2><\/div>If you summarize how these elements work together, the result is a surprisingly simple rule: Files in a Teams channel are stored in SharePoint. Files from a Teams chat are shared via OneDrive. And OneDrive itself is essentially a private SharePoint site. So, in the end, SharePoint is almost always behind all these processes, either directly or indirectly via OneDrive.<\/p>\n
This clarity is more than just a technical footnote. It explains why a presentation shared in a channel remains accessible to the entire team even after the original creator has long since left the company, while the same file can disappear from a private chat linked to that person\u2019s OneDrive. And it\u2019s essential for answering what is perhaps the most important question: Who is actually allowed to view and edit all this content?<\/p>\n<\/div>
How Permissions Work in Microsoft 365<\/h2><\/h2><\/div>Just as important as the question of where files are stored is the question of access rights. Microsoft 365 follows a clear, hierarchical structure that can be represented as a chain: from Microsoft Entra ID through Microsoft 365 groups and the Teams and SharePoint services, all the way down to individual document libraries, folders, and files.<\/p>\n
The starting point is Microsoft Entra ID, formerly known as the Azure AD directory service. This service stores information about which users exist in the organization and which groups they belong to. Based on this information, Microsoft 365 groups are created, which serve as central permission containers and bundle memberships across various services. When a team is created, Microsoft automatically creates such a group. This group controls not only access to the team itself but also to the associated SharePoint site.<\/p>\n
Permissions are inherited from the group through Teams and SharePoint down to libraries, folders, and individual files. The major advantage of this model is that access rights can be managed centrally through groups and team memberships without having to share each individual file separately. Anyone who is a member of the correct group automatically gains access to the relevant content and automatically loses that access when their membership ends. <\/p>\n<\/div>

<\/span><\/div>Why Individual Approvals Can Quickly Become a Problem<\/h2><\/h2><\/div>In practice, it\u2019s very tempting to quickly share a single document or folder directly with a specific person. It\u2019s convenient and useful in the moment. In the long run, however, this undermines the very clean inheritance logic that makes Microsoft 365 so easy to manage.<\/p>\n
The reason lies in a unique feature of SharePoint: As soon as a different, explicit permission is assigned to a subobject, this automatically interrupts permission inheritance at that point. Unlike with a traditional file server and its NTFS permissions, this break in SharePoint occurs, so to speak, automatically. With each individual permission granted, a coherent, group-based structure gradually turns into a patchwork quilt. The more such exceptions accumulate, the harder it ultimately becomes to understand who actually has access to what.<\/p>\n
That is precisely why experienced administrators recommend managing permissions through groups and team memberships whenever possible, and using direct sharing only where it is truly necessary. The most robust approach is to assign permissions at the site level rather than for each individual document. This keeps the structure manageable and auditable.<\/p>\n<\/div>
The Real Challenge: Keeping Track of Everything<\/h2><\/h2><\/div>As elegant as the permissions model is in theory, it becomes increasingly challenging in day-to-day operations. This is because Microsoft 365\u2019s built-in tools make it difficult to maintain a centralized overview of which files have been shared overall, which external shares exist, and what actual permissions an individual ultimately possesses. In an organization with hundreds of users, dozens of teams, and just as many automatically generated SharePoint sites, this quickly adds up to a nearly unmanageable volume of access permissions.<\/p>\n
Almost every IT department is familiar with the typical consequences: Employees retain access to an old project after switching departments; guest users aren\u2019t removed in a timely manner once a project ends; and a confusing landscape of access rights quietly grows out of individual direct approvals. What began as a convenient shortcut becomes an issue at the latest during the next audit or when considering standards such as ISO 27001, NIS2, or the GDPR. This is because these standards require proof that access rights are granted on an as-needed basis and reviewed regularly.<\/p>\n<\/div>
What This Means for Your Access Management<\/h2><\/h2><\/div>The key takeaway from all of this is good news: Because virtually all access routes go through SharePoint and the chain consisting of Entra ID and Microsoft 365 groups, this access can also be managed from a central location. You don\u2019t have to tackle the complexity of SharePoint, OneDrive, and Teams file by file; you just need to address it at the right level. Many organizations are surprised by just how much can be managed using the existing SharePoint structures alone.<\/p>\n
This is exactly where BAYOOSOFT Access Manager<\/a> comes in. The solution consolidates permission management across Active Directory, Microsoft Entra ID, file servers, SharePoint, Exchange mailboxes, and other line-of-business applications into a single, centralized interface, thereby providing transparency into who has access to what and on what basis. Through an NTFS Permission Analyzer and reporting that spans teams and SharePoint sites, effective permissions and external shares become visible, rather than remaining scattered across countless individual views.<\/p>\nThe real difference, however, lies in what happens between individual actions. A continuous target-actual comparison constantly checks the permissions actually granted against the defined target state, and a proactive auto-correction feature resets deviations based on rules before they turn into permanent permission clutter. Supplemented by self-service requests, automated Joiner-Mover-Leaver processes, recurring recertifications, and a complete audit trail, documented compliance becomes a permanently effective operational state. This ensures that Microsoft 365\u2019s well-designed permission logic remains not only clean at the time of setup but also stable and auditable over time\u2014without the need to review each file individually.<\/p>\n<\/div>
Conclusion<\/h2><\/h2><\/div>SharePoint, OneDrive, and Teams are not competing standalone solutions, but rather closely integrated components of a unified system. SharePoint serves as the foundation for working on documents and projects, OneDrive provides personal storage, and Teams brings communication and collaboration together in a single interface. Ultimately, almost every path leads through SharePoint, either directly or via OneDrive.<\/p>\n
Those who understand this interplay and the underlying access control logic can share files more securely and maintain a clearer overview. And those who manage the inevitably growing complexity not on a file-by-file basis, but at the central level using Entra ID, groups, and SharePoint, can transform a potential mess into a controlled, auditable state. That\u2019s exactly what the BAYOOSOFT Access Manager<\/a> is designed to do.<\/p>\n<\/div>

It explains why a presentation shared in a channel remains accessible to the entire team even after the original creator has long since left the company, while the same file can disappear from a private chat linked to that person\u2019s OneDrive. And it\u2019s essential for answering what is perhaps the most important question: Who is actually allowed to view and edit all this content?<\/p>\n<\/div>
How Permissions Work in Microsoft 365<\/h2><\/h2><\/div>Just as important as the question of where files are stored is the question of access rights. Microsoft 365 follows a clear, hierarchical structure that can be represented as a chain: from Microsoft Entra ID through Microsoft 365 groups and the Teams and SharePoint services, all the way down to individual document libraries, folders, and files.<\/p>\n
The starting point is Microsoft Entra ID, formerly known as the Azure AD directory service. This service stores information about which users exist in the organization and which groups they belong to. Based on this information, Microsoft 365 groups are created, which serve as central permission containers and bundle memberships across various services. When a team is created, Microsoft automatically creates such a group. This group controls not only access to the team itself but also to the associated SharePoint site.<\/p>\n
Permissions are inherited from the group through Teams and SharePoint down to libraries, folders, and individual files. The major advantage of this model is that access rights can be managed centrally through groups and team memberships without having to share each individual file separately. Anyone who is a member of the correct group automatically gains access to the relevant content and automatically loses that access when their membership ends. <\/p>\n<\/div>
<\/span><\/div>Why Individual Approvals Can Quickly Become a Problem<\/h2><\/h2><\/div>In practice, it\u2019s very tempting to quickly share a single document or folder directly with a specific person. It\u2019s convenient and useful in the moment. In the long run, however, this undermines the very clean inheritance logic that makes Microsoft 365 so easy to manage.<\/p>\n
The reason lies in a unique feature of SharePoint: As soon as a different, explicit permission is assigned to a subobject, this automatically interrupts permission inheritance at that point. Unlike with a traditional file server and its NTFS permissions, this break in SharePoint occurs, so to speak, automatically. With each individual permission granted, a coherent, group-based structure gradually turns into a patchwork quilt. The more such exceptions accumulate, the harder it ultimately becomes to understand who actually has access to what.<\/p>\n
That is precisely why experienced administrators recommend managing permissions through groups and team memberships whenever possible, and using direct sharing only where it is truly necessary. The most robust approach is to assign permissions at the site level rather than for each individual document. This keeps the structure manageable and auditable.<\/p>\n<\/div>
The Real Challenge: Keeping Track of Everything<\/h2><\/h2><\/div>As elegant as the permissions model is in theory, it becomes increasingly challenging in day-to-day operations. This is because Microsoft 365\u2019s built-in tools make it difficult to maintain a centralized overview of which files have been shared overall, which external shares exist, and what actual permissions an individual ultimately possesses. In an organization with hundreds of users, dozens of teams, and just as many automatically generated SharePoint sites, this quickly adds up to a nearly unmanageable volume of access permissions.<\/p>\n
Almost every IT department is familiar with the typical consequences: Employees retain access to an old project after switching departments; guest users aren\u2019t removed in a timely manner once a project ends; and a confusing landscape of access rights quietly grows out of individual direct approvals. What began as a convenient shortcut becomes an issue at the latest during the next audit or when considering standards such as ISO 27001, NIS2, or the GDPR. This is because these standards require proof that access rights are granted on an as-needed basis and reviewed regularly.<\/p>\n<\/div>
What This Means for Your Access Management<\/h2><\/h2><\/div>The key takeaway from all of this is good news: Because virtually all access routes go through SharePoint and the chain consisting of Entra ID and Microsoft 365 groups, this access can also be managed from a central location. You don\u2019t have to tackle the complexity of SharePoint, OneDrive, and Teams file by file; you just need to address it at the right level. Many organizations are surprised by just how much can be managed using the existing SharePoint structures alone.<\/p>\n
This is exactly where BAYOOSOFT Access Manager<\/a> comes in. The solution consolidates permission management across Active Directory, Microsoft Entra ID, file servers, SharePoint, Exchange mailboxes, and other line-of-business applications into a single, centralized interface, thereby providing transparency into who has access to what and on what basis. Through an NTFS Permission Analyzer and reporting that spans teams and SharePoint sites, effective permissions and external shares become visible, rather than remaining scattered across countless individual views.<\/p>\nThe real difference, however, lies in what happens between individual actions. A continuous target-actual comparison constantly checks the permissions actually granted against the defined target state, and a proactive auto-correction feature resets deviations based on rules before they turn into permanent permission clutter. Supplemented by self-service requests, automated Joiner-Mover-Leaver processes, recurring recertifications, and a complete audit trail, documented compliance becomes a permanently effective operational state. This ensures that Microsoft 365\u2019s well-designed permission logic remains not only clean at the time of setup but also stable and auditable over time\u2014without the need to review each file individually.<\/p>\n<\/div>
Conclusion<\/h2><\/h2><\/div>SharePoint, OneDrive, and Teams are not competing standalone solutions, but rather closely integrated components of a unified system. SharePoint serves as the foundation for working on documents and projects, OneDrive provides personal storage, and Teams brings communication and collaboration together in a single interface. Ultimately, almost every path leads through SharePoint, either directly or via OneDrive.<\/p>\n
Those who understand this interplay and the underlying access control logic can share files more securely and maintain a clearer overview. And those who manage the inevitably growing complexity not on a file-by-file basis, but at the central level using Entra ID, groups, and SharePoint, can transform a potential mess into a controlled, auditable state. That\u2019s exactly what the BAYOOSOFT Access Manager<\/a> is designed to do.<\/p>\n<\/div>
When multiple people collaborate on documents, projects, or information, SharePoint usually comes into play in Microsoft 365. The web-based platform has been part of the Microsoft portfolio since 2001 and serves as a central repository for the structured management of content within an organization. You can think of it as a company\u2019s shared file repository\u2014only in the cloud and with far more features.<\/p>\n
SharePoint is built around what are called “sites.” A site is a self-contained area that can contain document libraries, lists, pages, and other information, similar to a website with multiple subpages. Access to this content is typically restricted to specific users or groups. Behind the scenes, this access is managed through users and groups in Microsoft Entra ID, Microsoft\u2019s cloud-based directory service, which was known as Azure Active Directory until 2023.<\/p>\n
It\u2019s also important to know that SharePoint comes in two forms: as an on-premises server version (SharePoint Server) that runs in your own data center, and as a cloud service, SharePoint Online, within Microsoft 365. The online version is much more widely used today because it allows companies to outsource the costs of hardware and maintenance. In both cases, SharePoint serves as the technical foundation for many other services, including OneDrive and Teams. Typical use cases range from company-wide intranets and internal wikis to project sites where multiple departments collaboratively manage documents, spreadsheets, and schedules.<\/p>\n<\/div><\/div><\/div>
Microsoft OneDrive: The Personal Storage Service That's Actually SharePoint<\/h3><\/div><\/div>\nWhile SharePoint is designed for team collaboration, OneDrive serves primarily as a personal storage space. Every licensed user is provided with their own cloud storage (typically 1 terabyte) and can store, edit, and organize documents across any device. By default, only the owner has access initially; however, files can be shared with colleagues or external partners at any time.<\/p>\n
From a technical standpoint, OneDrive is also a SharePoint site\u2014albeit a private one that only the owner can access. You can therefore think of OneDrive as a personal version of SharePoint, tailored for individual document management. The service\u2019s greatest strength is its tight integration with Windows Explorer, which leads many users to perceive OneDrive as part of the operating system rather than as a separate application.<\/p>\n
However, it is precisely this association with a specific user that presents a common pitfall. If an employee leaves the company, access to their OneDrive content may be lost. This depends on how the tenant is configured and which retention policies apply. Microsoft generally does not delete the data immediately, but in practice, supposedly important documents frequently disappear because they were stored in a colleague\u2019s OneDrive instead of in a shared location. In addition, the version history in OneDrive is limited by default and also depends on the tenant\u2019s retention policies. The lesson here: Anything the team needs long-term belongs in SharePoint, not in a personal OneDrive.<\/p>\n<\/div><\/div><\/div>
<\/i><\/div>Microsoft Teams: The Interface That Brings Everything Together<\/h3><\/div><\/div>\nFor many users, Microsoft Teams is the central entry point to Microsoft 365. Chats, meetings, video conferences, shared files, and entire projects all come together here in one place. The primary organizational level consists of the \u201cteams\u201d that give the platform its name, where fixed groups such as departments, locations, or project teams coordinate their work. A person can be a member of multiple teams, and additional tabs allow users to integrate calendars, tasks, spreadsheets, or reports.<\/p>\n
The key point is this: Teams uses SharePoint and OneDrive for long-term file storage. Instead of maintaining its own storage, the application relies on existing Microsoft 365 services in the background. When you create a new team, Microsoft automatically creates an associated SharePoint site. All files uploaded or shared in a channel end up there. Teams is therefore less of a storage location and more of a convenient interface that brings communication and documents together in the right context.<\/p>\n
The situation is different for files sent in private chats or group chats. Teams first copies these files to the sender\u2019s OneDrive and then makes them available to the respective chat participants. This has an important implication: Files from conversations remain accessible only as long as the sender\u2019s OneDrive account is active, unlike content shared at the team level in SharePoint. Anyone familiar with this difference will immediately understand why a file is sometimes permanently available and other times disappears along with a colleague.<\/p>\n<\/div><\/div><\/div>
<\/div><\/div><\/div><\/div><\/div><\/div>Where does each file go? The simple rule of thumb<\/h2><\/h2><\/div>If you summarize how these elements work together, the result is a surprisingly simple rule: Files in a Teams channel are stored in SharePoint. Files from a Teams chat are shared via OneDrive. And OneDrive itself is essentially a private SharePoint site. So, in the end, SharePoint is almost always behind all these processes, either directly or indirectly via OneDrive.<\/p>\n
This clarity is more than just a technical footnote.

This is exactly where BAYOOSOFT Access Manager<\/a> comes in. The solution consolidates permission management across Active Directory, Microsoft Entra ID, file servers, SharePoint, Exchange mailboxes, and other line-of-business applications into a single, centralized interface, thereby providing transparency into who has access to what and on what basis. Through an NTFS Permission Analyzer and reporting that spans teams and SharePoint sites, effective permissions and external shares become visible, rather than remaining scattered across countless individual views.<\/p>\nThe real difference, however, lies in what happens between individual actions. A continuous target-actual comparison constantly checks the permissions actually granted against the defined target state, and a proactive auto-correction feature resets deviations based on rules before they turn into permanent permission clutter. Supplemented by self-service requests, automated Joiner-Mover-Leaver processes, recurring recertifications, and a complete audit trail, documented compliance becomes a permanently effective operational state. This ensures that Microsoft 365\u2019s well-designed permission logic remains not only clean at the time of setup but also stable and auditable over time\u2014without the need to review each file individually.<\/p>\n<\/div>
Conclusion<\/h2><\/h2><\/div>SharePoint, OneDrive, and Teams are not competing standalone solutions, but rather closely integrated components of a unified system. SharePoint serves as the foundation for working on documents and projects, OneDrive provides personal storage, and Teams brings communication and collaboration together in a single interface. Ultimately, almost every path leads through SharePoint, either directly or via OneDrive.<\/p>\n
Those who understand this interplay and the underlying access control logic can share files more securely and maintain a clearer overview. And those who manage the inevitably growing complexity not on a file-by-file basis, but at the central level using Entra ID, groups, and SharePoint, can transform a potential mess into a controlled, auditable state. That\u2019s exactly what the BAYOOSOFT Access Manager<\/a> is designed to do.<\/p>\n<\/div>
If you summarize how these elements work together, the result is a surprisingly simple rule: Files in a Teams channel are stored in SharePoint. Files from a Teams chat are shared via OneDrive. And OneDrive itself is essentially a private SharePoint site. So, in the end, SharePoint is almost always behind all these processes, either directly or indirectly via OneDrive.<\/p>\n
This clarity is more than just a technical footnote. It explains why a presentation shared in a channel remains accessible to the entire team even after the original creator has long since left the company, while the same file can disappear from a private chat linked to that person\u2019s OneDrive. And it\u2019s essential for answering what is perhaps the most important question: Who is actually allowed to view and edit all this content?<\/p>\n<\/div>
How Permissions Work in Microsoft 365<\/h2><\/h2><\/div>Just as important as the question of where files are stored is the question of access rights. Microsoft 365 follows a clear, hierarchical structure that can be represented as a chain: from Microsoft Entra ID through Microsoft 365 groups and the Teams and SharePoint services, all the way down to individual document libraries, folders, and files.<\/p>\n
The starting point is Microsoft Entra ID, formerly known as the Azure AD directory service. This service stores information about which users exist in the organization and which groups they belong to. Based on this information, Microsoft 365 groups are created, which serve as central permission containers and bundle memberships across various services. When a team is created, Microsoft automatically creates such a group. This group controls not only access to the team itself but also to the associated SharePoint site.<\/p>\n
Permissions are inherited from the group through Teams and SharePoint down to libraries, folders, and individual files. The major advantage of this model is that access rights can be managed centrally through groups and team memberships without having to share each individual file separately. Anyone who is a member of the correct group automatically gains access to the relevant content and automatically loses that access when their membership ends. <\/p>\n<\/div>
<\/span><\/div>Why Individual Approvals Can Quickly Become a Problem<\/h2><\/h2><\/div>In practice, it\u2019s very tempting to quickly share a single document or folder directly with a specific person. It\u2019s convenient and useful in the moment. In the long run, however, this undermines the very clean inheritance logic that makes Microsoft 365 so easy to manage.<\/p>\n
The reason lies in a unique feature of SharePoint: As soon as a different, explicit permission is assigned to a subobject, this automatically interrupts permission inheritance at that point. Unlike with a traditional file server and its NTFS permissions, this break in SharePoint occurs, so to speak, automatically. With each individual permission granted, a coherent, group-based structure gradually turns into a patchwork quilt. The more such exceptions accumulate, the harder it ultimately becomes to understand who actually has access to what.<\/p>\n
That is precisely why experienced administrators recommend managing permissions through groups and team memberships whenever possible, and using direct sharing only where it is truly necessary. The most robust approach is to assign permissions at the site level rather than for each individual document. This keeps the structure manageable and auditable.<\/p>\n<\/div>
The Real Challenge: Keeping Track of Everything<\/h2><\/h2><\/div>As elegant as the permissions model is in theory, it becomes increasingly challenging in day-to-day operations. This is because Microsoft 365\u2019s built-in tools make it difficult to maintain a centralized overview of which files have been shared overall, which external shares exist, and what actual permissions an individual ultimately possesses. In an organization with hundreds of users, dozens of teams, and just as many automatically generated SharePoint sites, this quickly adds up to a nearly unmanageable volume of access permissions.<\/p>\n
Almost every IT department is familiar with the typical consequences: Employees retain access to an old project after switching departments; guest users aren\u2019t removed in a timely manner once a project ends; and a confusing landscape of access rights quietly grows out of individual direct approvals. What began as a convenient shortcut becomes an issue at the latest during the next audit or when considering standards such as ISO 27001, NIS2, or the GDPR. This is because these standards require proof that access rights are granted on an as-needed basis and reviewed regularly.<\/p>\n<\/div>
