A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Dear @Mills, Philippa
Thank you for reaching out to the Microsoft Q&A Forum.
Based on what you've described, a blank page on your PC synced and overwrote the completed page on your Android, and the old version is not in the OneDrive recycle bin on your phone. From my own testing on an Android environment, the OneNote mobile app does not have the functionality to recover previous page versions or restore deleted notes directly. However, you should be able to recover the page on the OneNote desktop app (on your PC) or the OneNote web app. Please try the following steps:
-On the OneNote Desktop App (Windows):
- Select the History tab and select Notebook Recycle Bin.
- Right-click the page or section and choose Move or Copy.
- In the Move or Copy dialog box, choose where to put the recovered content and select Move.
- Select Notebook Recycle Bin again to close the recycle bin.
Note: You can recover a page or section up to 60 days after deletion. If you deleted a section group, you can recover the sections, just not the group. To recover a whole notebook, see Restore notes from a backup.
-On the OneNote for Web:
- In OneNote for the web, you can recover a page; deleting a section is permanent and can't be undone.
- On the View tab, select Deleted Notes.
- Select a section, right-click the page and choose Restore.
- In the Restore Page dialog, choose where to put the recovered content and select OK.
- Select Deleted Notes again to return to your notes.
Please refer the following documents from Microsoft:
