Shared folders not synchronising locally

Shared folders not appearing in local sync is a known issue with the legacy OneDrive client, and it won’t get fixed unless you move to the modern OneDrive (V2 – based on OneDrive.exe).

What to Do

Identify and stop Groove.exe.

Click the gear icon > Settings.

Unlink this PC or Stop syncing a folder.

Exit Groove.exe entirely.

Launch or install OneDrive.exe

Sign in and set up syncing

Open OneDrive.exe.

Sign in with your Microsoft account.

When prompted to set up folder sync, be sure to check “Shared folders” (if available) or add them afterward (see below).

Use “Add shortcut to My files” for shared folders

Go to OneDrive online.

Open the "Shared" section on the left.

Find the shared folder > Click "Add shortcut to My files".

Check that files now sync locally

If shared folders still won’t sync, check that:

The shared folder is added to "My files" (not just in “Shared with me”)

Your OneDrive folder location has enough permissions and disk space

You're using a supported version of Windows 10 (1903+) or Windows 11
