When I create an email alias for an end user with an existing AD/Exchange email account - what attributed is that stored in. I know that "mail" stores the SMTP address and mailnickname stores the part of the email address that precedes the @ in the mail address.
So where is an alias stored? If I have an email address of email@example.com then but an email alias of firstname.lastname@example.org then:
Mail = email@example.com
mailNickName = kthompson
But where is firstname.lastname@example.org stored...?
