How to Fix Missing OneNote Notebooks After Changing Your Surname

Product: Microsoft OneNote
Device & OS: not provided
Scenario: A user recently changed their surname or user principal name and is trying to access their existing notebooks and Office desktop apps.
Observed behavior: OneNote notebooks disappear, and desktop Word and Excel fail to recognize the user's account, despite email and online services working correctly.

Before you start

Ensure you have a stable internet connection and know both your old and new User Principal Name (UPN) or email address credentials before attempting to resync your account.

Solution 1Recommended

Sign Out and Re-Sign Into Office Applications

Manually signing out of all devices and signing back in with the new User Principal Name forces the Office apps to recognize the account changes.

When your account details change in Microsoft 365, local applications often cache the old credentials. Clearing this cache by signing out completely resolves the conflict.

Close affected notebooks

Close any affected notebooks in OneNote if they are still partially open or displaying sync errors.

Sign out of your account

Open desktop Word, Excel, or OneNote, click on your profile picture or 'Account' at the top right, and select 'Sign Out'.

Sign out across all devices

Repeat this sign-out process on all other devices (mobile phones, tablets, or other PCs) connected to the same Microsoft account.

Sign back in

Restart your Microsoft Office application and sign back in using your updated username and credentials to restore access.

Check OneDrive Online: Before signing in on the desktop again, log into OneDrive Online to verify that your missing notebooks are securely stored in the cloud.

Solution 2

Locate Notebooks via OneDrive Online

Use the web version of OneDrive to find missing notebooks and force them to open in the desktop app.

Frequently Asked Questions

Why did my OneNote notebooks disappear after changing my name?

Changing your User Principal Name (UPN) or surname alters the account identifier that OneNote uses to locate files on OneDrive. The desktop app fails to sync until you sign out and re-authenticate with the new credentials.

Do I lose my OneNote files if my User Principal Name changes?

No, your files are not deleted. They remain safely stored in your OneDrive or SharePoint. The issue is merely a synchronization disconnect between the desktop application and the cloud storage.

How do I force Word and Excel to recognize my new Microsoft account name?

You must manually sign out of the Office applications on all your devices, reboot your computer, and then sign back into Word or Excel using the newly updated email address and password.

Will changing my surname affect my Microsoft 365 subscription?

Generally, your subscription remains active and tied to your updated account. However, you may need to re-verify your license in the desktop apps by signing in again so the software can validate your active subscription.
