A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hello Byron Shoh,
I'm so sorry to hear that you accidentally deleted your OneNote content while clearing OneDrive. Since you have already emptied the Recycle Bin, there's a high chance that the notes are lost. Seeing the sections on your phone doesn't mean they are safely backed up as they could just be locally retained data. However, it's still something worth checking:
- Turn off both Wi-Fi and mobile data on your phone > open OneNote while the phone is offline
- Check whether the deleted sections and the actual contents of their pages are still available.
- If they are, preserve anything you can still access. Depending on what the mobile app allows:
- Export the OneNote content to your phone
- Copying the pages/content elsewhere.
Separately, you should also check OneNote's own deleted-notes recovery. Microsoft states that deleted OneNote pages or sections can be recovered for up to 60 days when they are still in the Notebook Recycle Bin. You can find Microsoft's instructions here: Recover deleted notes | Microsoft Support.
Regarding OneDrive itself, emptying its Recycle Bin generally means that the data is permanently deleted. However, if you have a Microsoft 365 subscription, there is an option to restore the entire OneDrive when something has gone wrong: Restore deleted files or folders in OneDrive | Microsoft Support.
I sincerely hope the complete pages are still available offline on your phone, as that may give you the best chance to preserve the notes.
