Dear @Anthony,
Thank you so much for contacting Microsoft Q&A Forum.
Based on your description, the error you're seeing, "the documents folder contains other important folders and isn't supported for backup", typically occurs when OneDrive detects system-managed folders (like Desktop, Pictures, Music, etc.) nested inside your Documents folder, even if they were manually created or renamed.
Reference: Back up your folders with OneDrive - Microsoft Support
As I am not fully aware of the specific contents within your 62 folders, I strongly recommend that you review them thoroughly, following the suggestions below:
1.Check for System Folders:
- Open your Documents folder.
- Look for folders named Desktop, Pictures, Music, Videos, or Downloads.
- Even if you created them manually, OneDrive may treat them as system folders and block backup.
2.Move or Rename Conflicting Folders:
If you find any of the above folders, try:
- Renaming them (e.g., “MyPictures” instead of “Pictures”).
- Or moving them outside the Documents folder.
3.Retry Backup: after renaming or moving the folders, go back to OneDrive settings and retry. Also, you can reset OneDrive before backing up files, see this link: Reset OneDrive - Microsoft Support
You can consult a similar scenario as your case here: OneDrive wont backup - Microsoft Q&A
I hope this information can help you to solve it soon.
Wish you a pleasant day!
