Troubleshooting: OneNote Needs a Password to Sync

  2. Click Credential Manager when you see it in the search results.
  3. Click Windows Credentials on the Manage your credentials screen.
  4. Under Generic Credentials, look for MicrosoftOffice16_Data:SSPI items. You’ll see one for each Microsoft account you’ve signed into on your computer. Expand the section by clicking the down arrow on the right for the account you want to clear.
  5. Click Remove.
  6. Click Yes on the confirmation dialog box that displays.
  7. Remove the other MicrosoftOffice16_Data:SSPI items to get a fresh start and make sure you can sync your notebooks.
