i think you didn't quite realise that your account is not deleted (as well as the inbox mails and messenger contacts) immediatly. yet, when you cancel your account it gets queued on some schedule for deletion. so only if you are terribly unlucky and suspend your account some seconds before "the daily hotmail database accounts refresh", you won't have any problem. if you just suspend it and then reactivate it, you won't have any problem.
and it worked just fine for me
