We have a fairly new Exchange 2007 SP2 install with some GAL issues - basically when you browse the GAL from Outlook 2007 there are users listed that are not email users.
If you look in Exchange under recipient configuration these users don't exist. They're AD users, but were never configured in Exchange, yet for some reason they show up in the GAL. The GAL seems to update correctly if new users are added or existing accounts are modified.
I was wondering if anyone had any insight on this? I have other Exchange 2007 installs that are fine and don't have this issue. This install was completely clean, no migration or anything of that nature.
