My wife has had a hotmail.com account for as long as she can remember and suddenly it has been deleted. I know this because I now get a failure notice when I try sending her an email. This email address was her first ever one and is linked to absolutely everything. She really needs it back.

I am not sure whether this is something to do with the migration to outlook.com or the fact that I made some changes to an Xbox live account that was registered with her email address. 

Long story short, my Xbox live account was using her email address as I couldn't remember my password when I set it up years ago. I recently changed it so that my email was registered as she was sick of getting emails related to FIFA etc, and in the process removed her email address off of it.

Did that somehow delete her email address?

Would really appreciate help as she is 8 months pregnant and waiting for urgent info from midwife and hospital etc
