We are in need of a address list in exchange based on contacts that are in a specfic OU. We have many external contacts and create OUs for each different company. For example all statefarm external contacts would be in a OU called statefarm and then we would have another OU called allstate and have all allstate external contacts in this OU. We want to be able to have a address list called statefarm that only list the external contacts in the OU called statefarm. What is the best way to acomplish this?
