Managing personal Outlook.com account settings, security, and privacy
I am having the same problem, my account got locked for some unknown reason. The application to unlock won't accept my phone number and its now been almost 3 weeks since I raised the call with the Microsoft Customer Service team (SIR0863101) and still not even a response (except for the automated one).. Its crazy, I have an upcoming flight that i can't get the details for. I have tried 2 online chats and both utterly useless. Microsoft need to sort this out.
