OneDrive Not Syncing on Windows 11? Compare the Web and File Explorer

Select the OneDrive cloud icon near the Windows clock and check the account in Settings. If you have both personal and work accounts, compare the matching OneDrive folder with the same account on the web. For a folder visible online but missing in File Explorer, open OneDrive Settings → Account → Choose folders and select it if available. A blue cloud beside a file in File Explorer means the file is available online and downloads when you open it with an internet connection.

If the icon is missing, search for OneDrive in Start and open the desktop app. A gray cloud with a line through it can mean you need to sign in or finish setup. If syncing is paused, select Resume syncing. If you see a red cross or warning, open the activity panel to read the message. If your cloud storage is full, freeing space only on the PC will leave the cloud quota unchanged.

Save and close the file. If OneDrive shows Processing changes after a large upload, see whether the queue is moving. Save a small new test document with a distinct name in the same folder and check whether it appears online. If the test file syncs but the original still fails, read the error for that file and check its name or whether another app has it open.

If the version online is older, save a separate copy of your latest work outside the OneDrive folder before changing the sync setup. Deleting an item in a synced folder can also delete it on the web. If the same account is in use and syncing still fails across folders, give Microsoft Support or your work or school IT team the exact status message and the result of the test upload.
