This username can usually be constructed from your email address inserting AD2\ plus the first 20 characters of your email address. Replace the @ symbol in your email address with an underscore (_). If the 20th character of your email address is a dot (.), replace it with an underscore (_). If your email address is less than 20 characters in length, then simply use all available characters.
