Fix OneDrive sync problems
- Select the OneDrive cloud icon. A red mark means you should open the list and read the file name in the error.
- If sync is paused, choose Resume syncing. A full local disk also pauses sync. Free some space.
- File names cannot include certain characters, and the full path must stay within Windows’ length limit. Rename or move a file that reports either problem.
- Choose the account in OneDrive settings and confirm it is the one that owns the files. Personal and work accounts can both be signed in.
Files On-Demand shows a cloud icon when the file is online-only. That is not an error. Open the file once to download it.
