Notebook went missing from onenote.

Question

I was working on a notebook and had to close the program. This is on a Microsoft surface BTW. When I reopened the program, my notebook was gone. All the other notebooks that I have were displaying that there was no data. Since then, I tried to check the backups, it isn't there either. The local back up will not let me open anything so i go to the OneDrive back up and that is were i can see some of my notebooks. I do see the first page of my missing notebook but it is categorized as a notebook now. The pages of this new notebook are the ones from my missing one.

Unfortunately, I am unable to restore anything to my program. Anytime I try to it says it is read only and has not been synced.

Let me know if there is more information you'd need to diagnose the problem.

I am trying to study for an exam right now so any help would be great!

Answer 1

I am getting a 404 file not found on onenote.com

and I am seeing the same problem on 365. I cannot sync anything.

So I was able to restore the program to a previous time and that restored the notebook that went missing, but as soon as turn the sync back on all the notebooks end up with nothing in them.

Answer 4

Check the web version of OneNote:

https://www.microsoft365.com/launch/OneNote

or https://www.onenote.com/

It is the "source of truth", since everything syncs from the cloud.
