Users are unable to open OneNote notebooks stored in OneDrive or SharePoint after an organization changes its primary domain.

How to Fix OneNote Files Missing After Changing Microsoft 365 Domain

Product: Microsoft OneNote
Device & OS: not provided
Scenario: A Microsoft 365 administrator or user updates the primary domain or User Principal Name (UPN), causing previously synced notebooks to become inaccessible.
Observed behavior: OneNote displays an error stating that the notebook location does not exist or that the user lacks the necessary permissions to access the file.

Before you start

Before attempting to re-establish the connection, ensure you manually copy and save any recently added, unsynchronized notes to a local document to prevent accidental data loss.

Solution 1Recommended

Reconnect OneNote to the New Domain URL

Re-establish the synchronization connection by signing out of the local app and launching the notebook from the online portal.

Changing your User Principal Name (UPN) does not delete your OneDrive data. However, it alters your OneDrive site URL, which breaks the active synchronization link in the OneNote desktop application.

Verify Online Access

Open a private or incognito browser window, navigate to the Office portal, and sign in with your new domain credentials. Open OneDrive to confirm your notebooks and files are present.

Sign Out of the Desktop App

Open the OneNote desktop application. Go to File, select Account, and sign out of your previous account to clear the old credentials.

Sign In with New Credentials

Still in the Account menu of the OneNote app, click Sign In and enter your new Microsoft 365 domain email address and password.

Reopen from OneNote for the Web

Return to your web browser where OneDrive is open. Click on the affected notebook to open it in OneNote for the web, then click the 'Open in Desktop App' or 'Open in OneNote' button on the ribbon to force a fresh sync connection.

Managing Multiple Users: If you are an administrator managing a large number of affected users, having them perform these steps manually can be tedious. It is recommended to contact Microsoft Support for automated PowerShell scripts to update the site collection URLs.

Frequently Asked Questions

Does changing my Microsoft 365 domain delete my OneDrive files?

No, changing your User Principal Name (UPN) or domain only updates your login credentials and the URL path to your OneDrive site. Your files and notebooks remain secure, though desktop applications may temporarily lose their synchronization link.

How do I back up unsynchronized OneNote pages before fixing the issue?

Identify any sections or pages in the OneNote app that have a sync error icon next to them. Manually copy the text or use the 'Export' feature to save those specific pages as a local PDF or Word document on your hard drive.

Why does OneNote say I don't have permission after a domain change?

The desktop application is still attempting to access the old OneDrive URL associated with your previous domain. Signing out of the app and re-authenticating with your new domain credentials will update the URL path and restore your access permissions.
