I have a Canon ScanFront 220 that is looking up our addresses using LDAP. The only configuration option that I have is "Search Base:", in which I have typed: ou=our domain users,dc=domain,dc=local. This works fine, except that it shows all of the hidden Exchange mailboxes that we have which is a big no no for us. Is there any way through that "Search Base:" that I can exclude all users that have a hidden Exchange mailbox? I have Exchange 2003 & Server 2003. Thanks in advance.
PS - Someone had mentioned in another post about using "!msExchHideFromAddressLists=*" but I can't figure out how to use that in the Search Base.
