Restore Access via SharePoint Advanced Permissions

Use this method to directly re-add affected users to the SharePoint Site Members group, permanently resolving the sync and access issue with Microsoft Teams.

Microsoft Teams channels rely on connected SharePoint sites for file storage and access management. When permission discrepancies occur, resolving them directly in SharePoint is the most effective approach.

1
Open SharePoint from Teams

Navigate to the affected channel in Microsoft Teams, click the 'Files' tab, and select 'Open in SharePoint' from the top toolbar.

2
Access Site Permissions

In SharePoint, click the gear icon in the top right corner to open Settings, then select 'Site permissions'.

3
Open Advanced Settings

Scroll to the bottom of the Site permissions pane and click the 'Advanced permissions settings' link.

4
Update the Site Members Group

Locate and click on the 'Site Members' group. Click 'New' or 'Add Users', enter the names or emails of the affected Teams members, and click 'Share' to restore their edit rights.

5
Verify Edit Access

Have the affected members restart their Microsoft Teams application and attempt to edit a file to confirm that full permissions have been restored.

Frequently Asked Questions

Why can't members edit files if they are already in the Teams channel?

Microsoft Teams uses SharePoint as its backend for file storage. If a user is accidentally removed from the underlying SharePoint Site Members group, they will lose file editing capabilities even if they are still visibly part of the Teams channel.

How long does it take for SharePoint permission changes to reflect in Teams?

Typically, permission updates sync between SharePoint and Microsoft Teams within a few minutes. If users still cannot edit files after 15 minutes, ask them to manually sign out and sign back into the Teams desktop or web app.

Can I fix these permission issues directly inside the Microsoft Teams app?

While basic member additions can be done within the Teams interface, resolving complex read-only conflicts or disconnected groups usually requires accessing the 'Advanced permissions settings' directly within the connected SharePoint site.
