Windows 10: Can't sign into my account to sync OneNote because of an unexplained error?

I use OneNote regularly, but a couple of days ago it stopped syncing and started to only save offline, stating "sign-in required". However, whenever I try to sign in, it simply bounces back an error with the incredibly nondescriptive message "Something went wrong" and the error code 0x80048504. If I continue to try and sign it it eventually times out the app for too many requests. I have no idea what could be causing this, as I don't think I've changed anything antivirus etc. I use Windows Defender if that's relevant that would suddenly be causing this issue. I don't have much more informati

Signing into Onenote app converts local account to microsoft account

The Onenote app also has broader account-related issues:

• Sign in with Microsoft account, and Onenote syncs to that.
• Remove this account from Onenote only, and add a different Microsoft account.

OneNote does not sync the new account's OneNote files, only sees the old account's files, and gives an error "OneNote needs a password to sync this notebook -> Sign In" where the "Sign In" button does nothing.

 

Signing into Onenote app converts local account to microsoft account

Steps:

• Sign into a local account
• Open the OneNote app (tablet not desktop app)
• Sign in to this app with a Microsoft account

The local account is then converted into a Microsoft account with that identity.

This is wrong and unexpected behaviour as no indication is given that the sign in is for the whole of windows rather than just OneNote.

It is also hard to revert.

I am guessing that other apps may exhibit the same behaviour.

In fact I don't understand how an app (which is supposed to be sandboxed and secure) can change user account information.

 

OneNote "Sync Conflicts"

Hi Tom,



Sync conflicts error shown in OneNote can be resolved by using OneNote desktop client. To stop seeing this error, can you follow the below steps:

1. Open the page which is having conflicts in OneNote desktop client or in Internet explorer
2. Open the page in which this error is shown
3. On the top of the page there will be a text bar shown. Pressing on the text bar will show conflicting pages for this page.
4. Delete the conflicting page by selecting the page and right clicking on it.
5. Sync the changes from desktop to server
6. After the above steps, open the page in Mobile and tap on "refresh" to get the changes made on the server.

After step 6 is done, sync conflicting error message should be stopped from prompting.

Hope this helps!
