Everyone:
Microsoft's account was not hacked. Some random person made an account named "Microsoft" before Google bought Youtube.
Since then, Microsoft (the company) got control of this address and the original account holder was given the boot. Looks like they didn't deactivate the original login credentials though.
All he did was log-in.
The original account holder was more of the victim in this case.
