What is 0x80042302 Error?


The error code 0x80042302 often appears when trying to start or use OneDrive, and it shows a message like “OneDrive is already syncing”. This typically indicates a conflict between OneDrive processes, an issue with Volume Shadow Copy Services (VSS), or corrupted system files that prevent normal operation.

Causes

  • Conflicting OneDrive Processes: Multiple instances of OneDrive running simultaneously can trigger the error.
  • VSS (Volume Shadow Copy Service) Failure: OneDrive uses VSS for backup and sync operations. If VSS is not working properly, sync errors may occur.
  • Corrupted OneDrive Installation: An incomplete or damaged installation can lead to persistent sync errors.
  • File or Folder Permission Issues: OneDrive may not have access to sync files due to permission conflicts.
  • System File Corruption: Corrupt system files may interfere with OneDrive services and VSS operations.

Resolution Steps




1. Restart OneDrive Completely:

Open Task Manager → End all “OneDrive.exe” processes → Restart OneDrive from the Start menu.

2. Check OneDrive Status:

Ensure your Microsoft account is properly synced and that there are no issues on OneDrive’s status page.

3. Run OneDrive as Administrator:

Right-click OneDrive → Run as Administrator. This gives it necessary permissions to operate correctly.

4. Use Windows Troubleshooter:

Go to Settings → System → Troubleshoot → Other troubleshooters → Select OneDrive or Files and Folders → Run the troubleshooter.

5. Repair OneDrive Installation:

Open Settings → Apps → Installed Apps → Search for OneDrive → Click Modify or Repair (if available) to fix potential corruption.

6. Restart Volume Shadow Copy Services (VSS):

  • Press Win + R → Type services.msc.
  • Locate Volume Shadow Copy → Right-click → Restart the service.
  • Also ensure Microsoft Software Shadow Copy Provider is running.

7. Run SFC and DISM Commands:

Open Command Prompt as Administrator and run:

  • sfc /scannow  
  • DISM /Online /Cleanup-Image /RestoreHealth  

These commands will repair any system file corruption that might affect OneDrive.

8. Check File/Folder Permissions:

Right-click the affected folder → Properties → Security tab → Ensure your account has Full Control. Adjust as needed.

9. Unlink and Re-link OneDrive:

Go to OneDrive Settings → Account tab → Unlink this PC → Restart and set up OneDrive again. This can clear sync configuration issues.

10. Perform Clean Boot to Avoid Conflicts:

Run msconfig → Services tab → Hide all Microsoft services → Disable all.

Then go to Startup tab → Open Task Manager → Disable all startup items → Restart the system.
