Scenario: Accessing and modifying student settings in a OneNote Class Notebook via Office.com.
Observed behavior: The notebook initially opens but repeatedly redirects the user to the sign-in page, displaying error messages stating that the notebook does not exist or that access is unavailable.

Before you start

Ensure you have your correct Microsoft 365 login credentials handy and note down the exact URL of the Class Notebook before clearing your browser data.

Solution 1Recommended

Sign Out and Clear Browser Cache

Resolves authentication conflicts by wiping outdated session data and forcing a fresh connection to Microsoft 365.

Sign-in loops are frequently caused by corrupted browser cookies or conflicting Microsoft 365 sessions when multiple accounts are used on the same device.

Sign out of Microsoft 365

Go to Office.com, click your profile picture in the top right corner, and select 'Sign out' to disconnect all active accounts.

Clear browsing data

Open your browser settings, navigate to the privacy or history section, and clear your cache and cookies (select 'All time' if prompted).

Restart the browser

Close all browser windows completely and reopen your browser to ensure the cache clearing is fully applied.

Sign back in

Navigate back to Office.com and log in using the specific account that owns or has administrative access to the Class Notebook.

Account verified: Logging in with a clean browser session ensures that you are connected exclusively to the account with the correct notebook permissions.

Solution 2

Update OneNote and Verify Organization Permissions

Ensures your application is running the latest version and confirms you have the necessary administrative rights to view the notebook.

Frequently Asked Questions

Why does OneNote keep asking me to sign in?

This usually happens when there is a conflict between multiple Microsoft accounts logged into your device or browser, or when your cached authentication tokens have expired and cannot refresh automatically.

How do I force my OneNote Class Notebook to sync?

You can force a manual sync by right-clicking the notebook name in the OneNote desktop application and selecting 'Sync This Notebook Now,' or by simply pressing Shift + F9 on your keyboard.

Will clearing my browser cache delete my OneNote notes?

No, clearing your browser cache and cookies only removes local temporary internet files and session data. Your OneNote notes are safely stored in the cloud on OneDrive or SharePoint.

What does the 'notebook does not exist' error mean in OneNote?

This error typically indicates that the notebook has been deleted, moved to a different folder location, or that your currently signed-in account lacks the necessary permissions to access it.
