Yes. This is, BTW, a Microsoft Account issue, not an Xbox issue; the Microsoft Account support folk have their own support forum at
http://windows.microsoft.com/windows-live/id-help-center
0) If you already have a second Microsoft Account (formerly known as the Windows Live ID) you can skip step 1 altogether
1) Make a new Microsoft Account at http://startup.live.com which after you complete it should lead you to the Account Summary
1A) If you don't get to the Account Summary page, go to
http://Account.Live.Com and sign in there.
1B) If you are prompted to cofirm the email address, please do so.
2) Complete the security information by clicking on the Edit Security Info link below. Make sure to add the Security Question down below as well as a cellular number in the Phone Numbers field and an alternate email address which is different from the Microsoft
Account address.
3) Then, enter http://go.microsoft.com/fwlink/?LinkID=242792 in the address bar of your browser. Fill in the form there, with the subject EMAIL BEHIND MICROSOFT ID IS BROKEN - give a good working
email where their support folks can find you. You should receive a response within a day, the gods willing.
