Question

I cannot access my One Drive One Note files from within One Note Desktop app.

Hello.

Even though I am signed in (with the same account, of course) in both One Note (browser) and One Note Desktop, the Desktop app cannot see the one note files that I can edit in the browser totally fine.
When I click Edit in Desktop App (From within the browser), I get this error:
2026-10-23_10h59_00

The one drive health status seems to be alright as it says "synced and backed up".
I have already tried reinstalling Microsoft 365 One Note, but without any success. I can access the files totally fine in browser's One Note.

Thank you.
Petros.

The error shown in your screenshot suggests that the desktop application is having trouble opening the notebook's cloud location, although this doesn't necessarily indicate an actual permissions problem since you can access and edit the notebooks online. Could you please confirm whether all your notebooks are affected or only specific ones? Also, are you using a personal Microsoft account or a work/school account? Finally, does the same error appear when opening a notebook directly from within the desktop application rather than using the Edit in Desktop App option in your browser?

As an additional troubleshooting step, please open the OneNote desktop application and navigate to File > Open > Open from OneDrive, then check whether your existing notebooks appear in the list. If they do, try opening one directly from there instead of using the browser link.

If the notebooks don't appear or the same error occurs, please try creating a small test notebook in OneNote for the web and check whether the desktop application can open it.
