We are set to finish our migration of several email domains over to our Exchange 2007 environment. One of the last issues to migrate across is the Exchange 2003 Recipient Update Policies, into the Exchange 2007 Email Address Policies.
Our current e2k3 RUP is a fine-tuned LDAP query:
(mailnickname=*)
(|(extensionattribute3=EXAMPLE*)(department=EXAMPLE*))
(|(objectCategory=group)(&(objectCategory=person)(objectClass=user)))
