Scheduling and managing events using Outlook.com calendar
I honestly doubt there is a solution, or if there is, I doubt it will ever be found.
Once again I gave MS access to my account, once again they stopped any contacts by PM. That was 2-3 weeks ago. I detect a pattern here. They just act interested in the problem but once they clarify it's not user fault and the user gives them all the access, they disappear in the mist.
