Does anybody know if there is a way to make a distribution group (static or dynamic) look at the mail attribute in ADUC and send to that email address? For example, in my organization, we have people have mailboxes that end with "@subdomain.domain.com" and others who have @domain.com, both of which are written to the mail attribute in ADUC. Also, I don't manage domain.com at all and don't have permissions to.
The main part of my question is for a user who is not mail-enabled, can we make a distribution group that works for that person based on the mail attribute in ADUC. Any help would be appreciated, thanks.
