How SharePoint Online and OneDrive for Business interact with Microsoft Teams


Watch the following session to learn how Teams interacts with Azure Active Directory (AAD), Microsoft 365 Groups, Exchange, SharePoint and OneDrive for Business: Foundations of Microsoft Teams

Each team in Microsoft Teams has a team site in SharePoint Online, and each standard channel in a team gets a folder within the default team site document library. Files shared within a conversation are automatically added to the document library, and permissions and file security options set in SharePoint are automatically reflected within Teams. To see the impact of changing a site address in SharePoint, read Change a site address.


This article applies only to standard channels. The architecture for private channels is different from standard channels. Each private channel has its own SharePoint site collection that's separate from the parent team site. To learn more, see Private channels in Microsoft Teams.

Private chat files are stored in the sender's OneDrive for Business folder, and permissions are automatically granted to all participants as part of the file sharing process.

If users aren't assigned and enabled with SharePoint Online licenses, they don't have OneDrive for Business storage in Microsoft 365 or Office 365. File sharing will continue to work in standard channels, but users won't be able to share files in chats without OneDrive for Business storage in Microsoft 365 or Office 365.

By storing the files in the SharePoint Online document library and OneDrive for Business, all compliance rules configured at the tenant level will be followed.


Integration with SharePoint On-premises is not supported for Microsoft Teams at this time.

The following is the example of relationships between team, standard channel, and document library.

For every team, a SharePoint site is created, and the Shared Documents folder is the default folder created for the team. Each standard channel, including the General channel (the default channel for each team) has a folder in Shared Documents.

It's not currently possible to replace the default SharePoint site and document library with another one. We've heard from you that you want it, and we're considering it. Check the Teams Roadmap or Teams UserVoice to stay on top of upcoming features.


To add a tab to your team that links to an existing SharePoint site page or to your existing SharePoint document library:

  1. Select the plus sign next to the tabs.
  2. Select either SharePoint for an existing SharePoint site page or Document Library for an existing document library.
  3. Select the appropriate page or document library.

For every user, the OneDrive folder Microsoft Teams Chat Files is used to store all files shared within private chats with other users (1:1 or 1:many), with permissions configured automatically to restrict access to the intended user only.

Note that for public teams, the SharePoint team site is provisioned with "Everyone except external users" access. The public team isn't displayed in Teams for people who aren't members of that team. However, they can access content on the SharePoint team site using the URL of the SharePoint team site.

Channel Files tab

This feature hasn't yet been released. It's been announced, and is coming soon. If you're an admin, you can find out when this feature will be released in the Message Center (in the Microsoft 365 admin center).

The Files tab in Teams closely resembles the SharePoint documents view. On the Files tab, users can:

  • See additional options in the New file menu.
  • Sync files to their local drive.
  • On the All Documents menu, switch from List view to Compact list to Tiles view.
  • Identify files that need attention or have malware.
  • Immediately see whether a file is read-only or checked out.
  • Check out and check in files.
  • Pin, unpin, and change the sort order of files.
  • Identify which files need metadata
  • Choose from many more filter options.
  • Group files based on column headings.
  • Modify column settings (move left or right, hide) and column width.

SharePoint and OneDrive have an admin setting for specifying the default link type for links that are created for a file. Teams is adopting that same approach by reusing the settings that the admin sets for SharePoint and OneDrive. More details about this approach are described in Change the default link type when users get links for sharing.
