A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
SOLVED!
here we go:
Microsoft creates a Cache user for your notebooks to be available in offline mode.
This hoses your Onenote when opening the program again out of sleep mode.
Onenote is looking to the Cached user for credentials and there are none.
So when it tries to Authenticate and you keep clicking on enter password it will never sign in.
Close Onenote and Go to
Control Panel
>User Accounts and Family Safety in Category view
(or Manage Accounts in Icon View)
>Credential Manager
>Windows Credentials
>There you will see the Cached users,
they are usually labeled as MicrosoftOffice15_Data:Live:cid=some set of numbers.
Delete those users as for every cached notebook there will be a cached user.
Once you have deleted those user open Onenote and enter the password for your live account.
It will connect and you will be able to sync your notebooks again.
