Well, I tried to log on to my hotmail acct I've had for years, only to be told that account doesn't exist!?

 I have tried"
1. re-setting password.
2. Using @outlook
3. loging in fm. a diff computer/network
4 logging in on my x-box

 Not sure what has happened, but have had this hotmail acct. for over 10 yrs. Not only can I NOT log into e-mail, but that acct. was linked to my x-box live acct as well. So locked out of both! I have had to set-up a entirely new outlook acct, but need to at least access old hotmail acct. to switch it at the very least. Folks at x-box won't even talk to me b/c it shows that acct. doesn't exist.

 Any help would be appreciated.
