OneDrive Sync Error code: 0x80004004

The following clean reset resolves 0x80004004 OneDrive sync issues in the vast majority of cases and is the safest reliable fix to try first:

Please follow these steps:

 1. Close OneDrive completely (Task Manager → end OneDrive.exe)

 2. Press Win + R and run:

%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset

 3. Wait 1–2 minutes, then start OneDrive again from the Start Menu.

 4. If the issue persists, rename this folder:

%localappdata%\Microsoft\OneDrive\settings

(for example to settings.old)

 5. Restart the PC and sign in to OneDrive again.

This process resets the local OneDrive sync configuration without affecting personal files and typically resolves cases where OneDrive gets stuck in a broken or incomplete sync state.

If it still does not work after this, the next step would be a clean reinstall of OneDrive.
