OneNote deleted my entire note when I deleted a picture in the note

If you accidentally deleted a note in OneNote, there are a few methods you can try to recover it:

1. Check OneNote Online: Sometimes, the web version of OneNote may show unsynced or older content. Open your notebook in OneNote for Web via OneDrive or SharePoint to see if the note is available there.
2. Search the Notebook: Use Ctrl+E to search across all notebooks for a unique keyword from the missing note. This can help locate the note if it was moved to another page accidentally.
3. Restore from OneDrive/SharePoint: If your notebook is stored in OneDrive, go to OneDrive → Documents → OneNote Notebooks → [Your Notebook] → Version History. You may be able to restore an earlier version of the entire section or page.
4. Local Backup: If you have local backups enabled, you can check for backup files in OneNote desktop by navigating to File → Options → Save & Backup → Backup Folder.

Please note that if the note was synced after deletion and no backup/version exists, recovery options may be limited, as OneNote does not have a "trash" for individual containers.
