Resolution

Make sure the app version is 4.4.120.8.1 (latest version) If this is not the case then you will have to update the app.

Going from the following:

Management Page -- Authentication -- OAuth -- Tokens  and delete the Microsoft online tokens where the user = KUID or Global admin. After this please go to the App catalog and run the registration wizard.

This should allow you use the app and the token should be refreshed also.
