Fix OneNote Web Sign-In Error and Notebook Sync Problems
Question details
The user is experiencing a sign-in and notebook access error on OneNote Web, alongside synchronization failures on the OneNote Android application.

- Product
- Microsoft OneNote
- Device & OS
- Windows, Android
- Scenario
- Accessing notebooks online via OneNote Web or syncing notebook changes across mobile devices.
- Observed behavior
- OneNote Web displays a specific notebook access error (reference number 5069cc68-28c0-463f-8f19-e4794e2590ad), and notebooks fail to synchronize updates on Android devices.
Before proceeding, open OneDrive in your web browser to verify that your latest notebook changes are safely backed up. Do not move or delete any notebooks until you have confirmed they are fully synchronized to prevent accidental data loss.
Clear Office Credentials in Windows and Restart OneNote
Removing corrupted login credentials from the Windows Credential Manager often resolves underlying sign-in conflicts and synchronization issues.
Windows stores your login information to keep you signed in across Microsoft apps. When these saved tokens become corrupted or outdated, it can trigger persistent access errors and prevent notebooks from syncing.
Close all open notebooks, sign out of your account from within the OneNote application, and then close the app entirely.
Click the Windows Start button, type 'Credential Manager' into the search bar, and hit Enter.
Select 'Windows Credentials' and scroll down to find any saved entries related to Microsoft Office or OneDrive.
Click the arrow next to these credentials and select 'Remove'. Once cleared, restart OneNote, sign back in with your Microsoft account, and wait for your notebooks to sync.

Access the Notebook Directly via OneDrive Web
If OneNote Web is displaying access errors, launching the notebook directly from your OneDrive folder can bypass the web portal glitch.
Reinstall OneNote on Android Devices
Performing a clean installation clears out corrupted cache files and corrupted sync states that prevent the Android app from syncing properly.
Try WPS Office for Seamless Document Management
If you are tired of dealing with persistent sync errors, corrupted credentials, and complex sign-in loops in Microsoft apps, consider switching to WPS Office. It provides a lightweight, highly compatible suite for all your document needs without heavy sync overhead.

- 2. Install and Sign In: Follow the installation prompts and sign in to enable seamless cloud syncing across your devices.
- 3. Manage Documents: Open, edit, and organize your files without worrying about complex credential conflicts.

Frequently Asked Questions
Why does OneNote Web show an access error with a long reference number?
This error typically occurs due to cached credential conflicts in your browser, a temporary server glitch on Microsoft's end, or corrupted notebook sync states. Clearing your browser cache or launching the notebook directly from OneDrive can often bypass the error.
Will reinstalling the OneNote Android app delete my notes?
Reinstalling the app will remove locally cached data. If your notes were not fully synced to OneDrive beforehand, un-synced offline changes might be lost. You should always verify your notes are visible on OneDrive Web before uninstalling the application.
How do I check if my OneNote notebooks are safely synced?
Go to the OneDrive website on your computer, navigate to the folder containing your notebooks, and open them in the web browser. If you can see all your recent edits there, your notebooks are safely synced to the cloud.
Why didn't clearing Windows Credential Manager fix the sync issue?
If clearing Windows Credentials doesn't resolve the sync problem, you might be facing a network block, an active firewall restriction, or you could be signed into a conflicting Microsoft account. Verify your account details and try switching networks to rule out connectivity issues.
