"To sync this notebook, sign in to OneNote."

When I open one particular notebook in OneNote 2016, OneNote displays the message:

"To sync this notebook, sign in to OneNote"

and the Shared Notebook Synchronization window shows this error:

"We need the password to sync this notebook. (Error code: 0x803D0005) There was an error communicating with the endpoint at [my OneDrive]; The server returned HTTP status code '401 (0x191)' with text 'Unauthorized'.; The requested resource requires user authentication.; The operation identifier is not valid."

Error code 0x803D0005 means that OneNote is unable to communicate with the OneDrive server where my notebooks are stored, and the reason is HTTP status code 401, which means that OneNote's request to my OneDrive lacks valid authentication credentials - my password. The error message does not reference any Section in particular.

According to File > Account > User Information in OneNote 2016, I am in fact signed in to my Microsoft account. Nevertheless, if I open the affected notebook in OneNote for the web (with the notebook's URL) I can see that recent changes have not synced.

Manually syncing my notebook solves the problem (and I'm not asked to enter my password.) I want to know why this one notebook won't sync automatically - why I must sync it manually?

It's not an issue with OneDrive, since according to Microsoft's Service Status web page OneDrive is up and running.

To anyone who likes to answer by copying URLs for me to read: I have already read and performed the steps in Troubleshoot synchronization errors in OneNote 2016 for Windows and Fix issues when you can't sync OneNote. In addition, please know that my OneNote notebooks are not stored on Sharepoint and no one else collaborates on any of my Notebooks. Also, please know that I have already uninstalled and re-installed OneNote 2016.

    Hi BulldogXX,

    Thanks for reaching out. I hope you're having a great day, despite the issues you're experiencing with OneNote. Let's try to address your concern.

    It seems that the issue only occurs on a specific notebook. Have you tried recreating/copying the contents of the notebook to a new notebook? This would let us cross out the possibility of a corrupted notebook. This is besides the fact that the issue is not occurring when doing a manual sync of the notebook in question, which is also rather unusual.

    Seeing that you have exhausted all possible troubleshooting steps to resolve the issue. We also highly recommend that you take advantage of your Office 365 subscription. Our representatives have the option of doing a remote session on your device in order to do more advanced troubleshooting to resolve the said sync issue. Click here to get in touch with them.

    Should you have any other concern, don't hesitate to post back in the Community.

    Greetings Regile Reb,

    Have you tried recreating/copying the contents of the notebook to a new notebook?

    Yes, I actually did: That was one of the troubleshooting procedures recommended in Fix issues when you can't sync OneNote.

    'Your' representative suggested that I try to identify the page or pages in my notebook that cause the error to happen. I think it's unlikely that individual pages cause the problem, since OneNote 2016 syncs notebooks, not pages. Nevertheless, I'll give the suggestion a try.

    Should you have any other concern, don't hesitate to post back in the Community.

    Sounds like you're done with me, so have a good day.

    I appreciate you providing updates regarding the issue.

    It is true that OneNote syncs notebooks, and not pages. However, the suggestion provided by our representative is to further isolate if the issue is with the contents of the notebook in question itself.

    You may post back on this thread for any other findings that you have as you work with our Office 365 Chat Support in further troubleshooting the issue.

    Regards.

    Clark Wang MSFT's answer at https://answers.microsoft.com/en-us/msoffice/forum/all/onenote-always-asks-to-sign-in/ worked for me. I did both steps, so not sure if only one was necessary.

    This link no longer exists? So what is the fix? Can it be posted here?
