We have hundreds of external e-mail addresses that we send to on a regular basis. I would like to add all of these addresses as contacts in Active Directory and then add them to a Global Address List. This way we could avoid each of our users having to maintain a large contact list on each of their accounts. I want this address list to be completely separated from our current global address list. It would be great if I could add just a specific AD OU to this list. If any one has an idea it would be greatly appreciated.
