1. Open the OneDrive cloud icon and select View sync problems to identify the first blocked file or folder.
2. Check invalid characters, path length, available storage, and whether the file is still open in another application.
3. Pause and resume syncing, then test the same file at onedrive.com to distinguish a local-client issue from a cloud issue.
4. Copy unsynced local files to a safe folder before resetting or unlinking OneDrive, then verify a small upload after relinking.
