If a site name includes a character such as “:” that isn’t supported in folder names in Windows, files on the site can’t be synced. To move Office files, go to the site, and use the Move to or Copy to command. You can't move OneNote notebooks from one site to another on your computer, and if you move other Office files between sites, version history will be lost. If you change the files on your computer, the changes won’t sync. You might not have permission to edit the files, or the library might require checkout or have required columns or metadata. If you see a lock icon on synced files in File Explorer, it means the files are synced read-only. When that finishes, open the SharePoint or Teams location or OneDrive in your browser, and to begin syncing it with the sync app, select Sync. Then, install the Rights Management Service (RMS) client.

If you’re currently syncing an IRM-protected location using the Transition from the previous OneDrive sync app, stop syncing it with that sync app first.

You can now sync IRM-protected SharePoint, Teams, and OneDrive files in your work or school account.
