Does anyone know if it is possible to modify Filter Rules in Exchange 2000 to query OU Membership. Example 1: when modifying Address Lists, I would like to be able to show all users in each OU separately. Example 2: when creating Recipient Policies (I'm trying to host multiple SMTP domains), I would like to be able to apply the policy only to users in a particular OU, regardless of which Exchange Server or Mail Store they are in. Thanks in advance.
