Seems MS has put us in OPATH hell ! First we learn how to write ldap queries.. now we get something even less powerful and get to try to convert everything to OPATH. So.. my question is this.. in 2003 EAP and AL I used LegacyDN to create address lists and EAP ... which to be honest wasnt very good either since what I really wanted was to apply EAP based on domain membership (AD domains). We have multiple domains hosted on one exchange server .. each domain gets a different SMTP address. So.. now I'm trying to get OPATH to do this.. no luck at ALL !
