Microsoft Account Autorisation Error

With my hotmail (windowslive.com) Account I get an "autorisation error of the Microsoft Account" all the time. But all the functions seem to work and sync properly, I also tried to unbind and reconnect onecalendar to the account and to "repair" it (link in the error message) and allow all the authorisations asked for. But none has worked so far and the problem still exists. It's sad because other than that it'd be easily the best calendar app out there. I hope it can be fixed in the future.
