I work with Windows live messenger as a chat inspector, and your isssue sounds like that's what happen is your friend got hit by that server downfall, There "IS" A way to recover your email. and If this is what I think it is, has nothing to do with SAS

what you need to do is, log into windowslivehelp and post the excate email address they will remove it once they see it so no one else gets it, and they should reply back to you.
Hope this helps.
