I have 4 remote sites connected via Frame Relay back to our main office. The first problem is, the recipients lists never seem to get updated for any of the sites. The trusts have been established, Admin group from all domains have Service Acct Admin rights to each Site and Configuration container. The directory replication has been configured into the main office, then main office is configured to send OutBound to the other offices. The second problem is one particular site has yet to get the main recipient list and hasn’t passed its list to the main site. It is configured the same as the other three remote sites. The main site can ping the remote site and view files and such.
I have SP 3 for Exchange on all machines and SP6a for NT on the servers. Exchange runs at the PDC at all locations. All other functions in Exchange seem to work from the remote offices, mail sends quickly.
