ISSUE

You no longer have permission to access this notebook. We’ll sync again if permissions are restored


To me the error message comes on Windows 11, OneNote 2021, after a fresh installation of Microsoft Office 2021. I have one notebook open, and it is mine, on my OneDrive, and is not shared with anyone. I have never tweaked with the permissions.
 
The error message appears for a brief moment, when I open OneNote, and disappears afterwards. It does not appear at every starting of OneNote. E.g. if I close the program, and immediately reopen it, the message does not appear.
 
Since the message comes after a fresh Office install, I do not believe, that a reinstall would solve the problem.
 
About half year after posting this, the error message disappeared. Microsoft seems to have fixed it. Thank you, Microsoft!

Answer:

This seems to happen when Windows local login credentials are changed or added post authentication (in my case forcefully "net use <user> *"). There is some credentialing magic happening that really messes with known permissions.
 
Anyhow I was able to fully rectify this issue by closing OneNote and renaming the OneNote cache directory (C:\Users\<user>\AppData\Local\Microsoft\OneNote\16.0\cache) to cacheOLD and relaunching the application. This will cause a rebuild of the cache dir and full sync/auth and should smoke out any gremlins.
 
tldr: rename OneNote cache directory and restart app.
