OneNote page did not sync and now I cannot find it anywhere?

Dear Dexter, Dex

Welcome and thank you for sharing your issue in the Q&A forum.

Based on the information you have provided, I am truly sorry to hear that your data is now at risk of being completely lost, despite the fact that you have tried almost every possible location to recover the data.

Based on my analysis:

• The note page existed only locally on your tablet (due to the initial sync error).
• The process of signing out and signing back in cleared or overwrote the local application cache on the tablet, which stored the unsynchronized page.
• Since the page was never uploaded to OneDrive and the original local data has been erased, no other recovery tools or methods provided by Microsoft for OneNote can retrieve this data.

To prevent this issue from recurring, here is a crucial rule when encountering a OneNote sync error:

• Absolutely do not sign out of your account or uninstall the application if you have unsynchronized data (indicated by an X or warning symbol next to the page/notebook).

Instead, you should:

• Copy the entire content of the page that has the sync error.
• Paste that content into another temporary note application (such as Notepad, Word, or your tablet's basic Notes app).
• Once the content is safely backed up, you may then proceed with troubleshooting steps (like signing out/signing back in).

I sincerely apologize that I could not help you recover the lost note page. We apologize for the inconvenience and appreciate your patience. If you need further assistance or have any other questions, please do not hesitate to contact us. We're here to support you.
