We have a Windows 2003 Server Active Directory environment. In AD you can enter a person's email address. Back when we used to have Exchange, when creating a new user it would also create an entry in Exchange. We have not had Exchange in years, but when creating accounts, or modifying their profile in AD, I've left the email address portion blank, because I wasn't sure what would happen. Now I'd like to know, can we create an account or modify an existing account, and also add their email address, even if it isn't a part of our domain? (Such as when they have a Hotmail or Gmail account.)

mailattribute does not need to contain an address within the Active Directory domain. In fact, there is not input validation on the field -- you may enter a string which is not a valid email address.
