Repair OneDrive Sync
Repair OneDrive Sync fixes synchronization failures between your PC and OneDrive cloud storage. It resets the OneDrive sync engine without deleting any files, clears the metadata cache that tracks file states, repairs the sync database, resolves conflicted file states, and re-establishes the connection to Microsoft's sync servers. It handles the most common sync failures: stuck pending states, authentication expiry, file lock conflicts, and corrupt metadata. No files are deleted from your PC or cloud — only the sync state is reset. Takes about 3 minutes; OneDrive will re-scan all files which may take longer on large libraries.
