Click the OneDrive cloud icon to see the specific error. Common causes are being signed out, invalid characters in file names, file paths that are too long, a full OneDrive or full local drive, and files that are open in another program.
Common causes
Signed out or paused
OneDrive may have paused syncing or need you to sign in again.
Invalid file names
Some characters and names aren't allowed in OneDrive and SharePoint.
Path too long
Deeply nested folders can exceed the maximum path length.
Storage full
A full OneDrive account, SharePoint site, or local drive stops syncing.
Files in use
Files open in other programs, like Access databases or QuickBooks files, may not sync properly.
