Email address does not exist - message


New Email
Hi, my hotmail email address - I have had for several months, no problems.
I requested a code from Microsoft and when I tried to log in I got the message saying "That Miicrosoft account does not exist".
However, I can send an email to this account from my alternate email, so I know it exist. I have read the forum. How can I get back my mail address?
Please help me?
