Are the two domains in the same AD forest? If not, you have two organizations and you will need some sort of third party directory syncronization utility to essentially create contacts on one side for mailboxes on the other.

I am trying to host a single domain, named us.com on two separate exchange 2000 servers that are each in a separate routing group connected by a routing group connector. However, it is not possible to send mail between recipients hosted on each exchange server, since a bounce occurs. Apparently, the same domain cannot be hosted on two exchange servers that are in SEPARATE routing groups. The above scenario DOES WORK if placing the two exchange servers in the SAME routing group. It appears that having exchange servers in the same routing group ensures that both exchange servers are using the same global catalog in active directory to deliver mail. The way my domain is split is so that one server, call it server A, hosts part of mailboxes for domain us.com. Server B hosts part of mailboxes for domain us.com and all mailboxes for domain europe.local. Both server A and B are primary domain controllers with active directory, DNS and Exchange installed on a single machine. Why do server A and B have to be in different routing groups and have to host the same domain? Server A is located in the US, server B is in Europe. They are connected via a rather reliable VPN. Only server A has a static Internet IP assigned, therefore server B cannot directly accept messages from the Internet; it is connected to a DSL modem with a dynamic IP. Users on server A and B share the same domain name - us.com; user account and mailbox for [EMAIL PROTECTED] is located in the US on server A, while user account and mailbox for [EMAIL PROTECTED] is located in Europe on server B. European users (connecting to server B) cannot have their accounts hosted on server A, since they use Outlook to connect to server B locally. The same, European, users also must have @us.com domain email set as Primary SMTP Account, with the intranet SMTP address @europe.local set as secondary SMTP account. ACTIVE DIRECTORY IMPLEMENTATION: Server A is PDC for domain us.com and has a trust relationship established with server B that is PDC for domain europe.local. Both domains are within the same forest. The DNS entry for domain us.com is on server A, a secondary copy of the domain us.com is stored in server B's DNS. The MX record for domain us.com is pointing only to the exchange server A, the host being a.us.com. Is there a better DNS configuration for what we want? Both Exchange servers are in the same Exchange organization and in the same administrative group. Once routing connectors are created, servers are connected to each other, everything appears to be working in the monitoring view. Is there any way to implement this scenario with two Exchange servers in separate routing groups. Once again, this scenario works with the two servers in the same routing group, where it appears that mailboxes within the same domain can be spread across multiple exchange servers. But we need to separate the two servers, since they are not connected in a LAN, and we are also using fax connectors that each must work within a separate routing group with a separate server. I would greatly appreciate any help!
