Question details
Users are unable to sync or open their OneNote 2016 notebooks after migrating to a new Windows 11 computer.

- Product
- Microsoft OneNote 2016
- Device & OS
- Windows 11
- Scenario
- Migrating to a new PC and attempting to access or sync existing OneNote notebooks.
- Observed behavior
- OneNote stops synchronizing, displays ownership errors, or fails to open notebooks online.
Ensure your computer has an active internet connection and verify the exact email address and password for the Microsoft account associated with your notebooks.
Verify Account and Re-sign into OneNote
Sync issues often occur due to authentication glitches on a new PC. Re-signing in refreshes the connection to your Microsoft account.
When moving to a new Windows 11 computer, cached credentials can cause conflicts, leading OneNote to report that you are not the owner of your own notebooks.
Launch OneNote 2016 on your Windows 11 computer. Click on 'File' in the top-left corner and select 'Account' from the left-hand menu.
Check the User Information section to ensure you are logged in with the exact Microsoft account that originally created and owns the notebooks.
Click 'Sign out' under your account details. Close OneNote completely, then reopen the application.
Go back to File > Account, click 'Sign in', and enter your Microsoft account credentials to restore the synchronization connection.
Check Microsoft Office Service Health
Sometimes synchronization failures are caused by server outages on Microsoft's end rather than a problem with your new computer.
Gather Error Details for Microsoft Support
If local troubleshooting does not resolve the sync issue, gathering specific error codes to provide to Microsoft support is the best next step.
Try WPS Office for Seamless Document Management
If you are tired of sync errors and complex troubleshooting in Microsoft Office, try WPS Office. It provides a lightweight, highly compatible suite for all your document, spreadsheet, and presentation needs without the hassle.

Frequently Asked Questions
Why does OneNote say I don't have permission to sync this notebook?
This usually happens if you are logged in with a different Microsoft account than the one used to create the notebook. Verify your active account credentials by navigating to File > Account in OneNote 2016.
Do I need to buy Microsoft 365 to fix OneNote 2016 sync errors?
No, an upgrade is not required. OneNote 2016 sync issues are generally related to account authentication, temporary server outages, or local cache errors rather than licensing.
Where are my OneNote 2016 local backups stored on Windows 11?
By default, local backups for OneNote 2016 in Windows 11 are located in C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote\16.0\Backup. You can access these files if cloud synchronization fails completely.
