The message 'To sync this notebook, sign into OneNote' shows on a yellow bar across the top of my OneNote application. How can I fix this?

1 Answer 1


I have managed to fix this in the past by doing the following:

  • Search for 'Credential Manager' via the start menu
  • Click 'Windows Credentials'
  • Look for 'MicrosoftOffice16_Data:live:cid=' and delete/remove it
  • Sign into OneNote again

The error should disappear and the problem should be fixed.
