Error when opening a file in Teams: You don't have access to this file


In Microsoft Teams, you share a file with another user in a chat window. Then, the file is automatically stored on your OneDrive site. When the other user tries to open the file in Teams, the following error message is displayed:

You don't have access to this file.


This issue occurs because the Limited-access user permission lockdown mode feature is activated on your OneDrive site. This is a site collection feature that helps prevent anonymous users from accessing application pages that are mostly helpful on classic, publishing-based SharePoint sites. We recommend that you do not enable this feature on OneDrive sites.


To fix this issue, deactivate this feature in OneDrive.

  1. Sign into your OneDrive site.
  2. Select the Setting icon in the upper-right corner of the screen.
  3. Select OneDrive Settings > More Settings.
  4. Under Features and storage, select Site Collection Features.
  5. Locate Limited-access user permission lockdown mode, and then select Deactivate.

For more information about Limited-access user permission lockdown mode, see Enable or disable site collection features.
