I'm wondering whether or not this is possible.
Our staff use email based on Exchange 2013.
Our students however use googlemail. Each student account has an email address listed in the mail attribute in AD but this doesn't get listed in the Address list as they are not mail enabled.
What I'd like to know is there a way to create an additional address list that populates itself using the mail attribute where mail ends @student.com?
If it is possible, how?
