Hello Diana,
Thank you for reaching out in Microsoft Q&A forum.
Regarding the issue with your OneNote notebook synchronization, I understand how important your notes and pictures are, and I know how frustrating that situation can be.
Please try the following solutions to try to recover your data:
- Check OneDrive Version History
- Sign in to https://onedrive.live.com.
- Locate your OneNote notebook folder.
- Right-click the notebook file and select Version History.
- Restore a version from before the sync issue.
- Use OneNote Page Version History
- Open OneNote on your PC.
- Navigate to File > Info > View Versions.
- Select an older version of the page and restore or copy the content.
- Recover Lost Pictures
- Check OneDrive Photos and Recycle Bin for deleted images.
- Also review your Android device’s backup (Google Photos or local cache).
- Local Backup
- On your PC, look in:
-
C:\Users\<YourName>\Documents\OneNote Notebooks -
%LOCALAPPDATA%\Microsoft\OneNote - These folders may contain older notebook copies.
