Its happened to me a few times in the past, as well as today, but why does the hotmail.com or outlook.com email address get suspended when blizz suspend wow licence?
The two services you are talking about have nothing to do with one another so it's either some kind of coincident or you've done something wrong.
stupid question do you have a lot of hotmail accounts? i have had gmx.com and mail.com start suspending accounts for having too many.
