Hello kent saw,
Thank you for reaching out in Microsoft Q&A forum.
I understand how confusing it is when OneDrive suddenly stops syncing your Personal folder after you changed the backup settings.
Based on what you described, this usually happens when PC Folder Backup was turned ON, then turned OFF midway, causing OneDrive to keep the folder in a “partially disconnected” state.
You can try these steps to fix it:
- Check if the folder is still being protected by PC Folder Backup
- Right‑click the OneDrive cloud icon> Select Settings > Go to Sync and backup > Click Manage backup
- If Documents / Desktop / Pictures shows Error > click Stop backup
- Wait for it to apply, then restart your laptop
- Reconnect the folder manually
- Right‑click the OneDrive icon > Choose Settings > Go to Account > Choose folders
- Ensure your Personal folder is checked
- If it shows an error > click Unlink this PC, then sign in again
- Check for leftover junction links. Sometimes Windows leaves old “redirect” links behind.
- Open File Explorer > Right‑click your Documents folder > Properties > Location
- If the path is not your real Documents folder, click Restore Default > Apply and restart
