hotmail account wrong


New Email
hi, I set up an email account for my boyfriend and he only used it to play texas holdem and a few emails from his brother. The name I came up for him was very original and special to him as was his pass word. Our computer broke down a few years ago so I have a droid 2 and have been able to get into his account and clean out junk, like I do with my hotmail account that I never really use. Now It says that either his login name is wrong or password, so I go to reset password and it says the user name doesn't exit. What's going on with hotmail and, or windows live? And how can he get his user name back? It was Thanks and would really appreciate his user name restored.
