Question details

An organization needs to allow members from three different Microsoft Teams groups to access and collaborate on the same SharePoint site.

Product: Microsoft Teams and SharePoint
Device & OS: not provided
Scenario: Managing cross-departmental collaboration where multiple distinct Microsoft Teams groups require access to a centralized SharePoint site.
Observed behavior: By default, a SharePoint site created via Microsoft Teams is only associated with one primary Microsoft 365 group, requiring additional configuration to allow other Teams groups to access it.

Before you start

Ensure you have Site Owner or Full Control permissions for the target SharePoint site and know the exact names of the Microsoft Teams groups you want to grant access to.

Solution 1Recommended

Grant SharePoint Permissions Directly to the Teams Groups

Since a SharePoint site cannot be linked to multiple Teams groups via a primary relationship, you must manually grant each Teams group the necessary SharePoint permissions.

When a SharePoint site is created via Microsoft Teams, it is natively connected to a single Microsoft 365 group. To allow other Teams groups to access the same site, you must add those groups to the SharePoint site's permission settings.

Open SharePoint Settings

Navigate to your target SharePoint site as a Site Owner. Click the gear icon (Settings) in the top right corner and select 'Site permissions'.

Access Advanced Permissions

At the bottom of the Site permissions panel, click on 'Advanced permissions settings'.

Grant Permissions

Click 'Grant Permissions' on the ribbon menu. In the 'Invite people' dialog box, type the names of the three Microsoft Teams groups you want to give access to.

Set Permission Levels

Click 'Show Options' to select the appropriate permission level (such as Read or Edit) for these groups, then click 'Share' to apply the changes.

Microsoft 365 Groups Integration: When you search for the Teams groups in the SharePoint permissions dialog, you are actually searching for the underlying Microsoft 365 Groups associated with those Teams.

Solution 2

Add the SharePoint Site as a Tab in Teams Channels

Make the SharePoint site easily accessible to the other Teams groups directly within their Microsoft Teams interface by adding it as a channel tab.

Frequently Asked Questions

Can I automatically merge three Microsoft Teams groups into one SharePoint site?

No, a SharePoint site created via Microsoft Teams is directly linked to only one primary Microsoft 365 group. Members of other groups must be manually granted access through SharePoint's permission settings.

Will adding a SharePoint tab in a Teams channel grant permissions automatically?

Adding a SharePoint tab in a channel only creates a shortcut; it does not automatically grant the channel members permissions to the site. You must configure the site's permissions in SharePoint first.

Can external guests in a Teams group access the shared SharePoint site?

Yes, if the Teams group is granted access to the SharePoint site, any guest members within that group will also inherit access, provided that external sharing is enabled on the SharePoint site level.

What permission level should I give to the additional Teams groups?

It depends on their required role. Assign 'Read' access if they only need to view documents, or 'Edit' access if they need to create, modify, and collaborate on files within the SharePoint site.
