As a school, we run an admin domain and an academic domain. There are no trust relationships between the two, as they run entirely independently for (primarily historical) security reasons. Each have their own independent exchange 2007 server. I know in Exchange 2003 it was not possible to have each able to view & send to the other's GAL, but is this now possible in Exchange 2007 and, if so, how? We particularly need to allow the admin domain to view the GAL from the academic domain.
