This is more for clarification purposes then anything else. We are about to open a branch office and are going to be introducing another Exchange 2003 server into our domain. The two offices will be connected via an MPLS link. I am thinking that all I should need to do is just install the server and join it to the domain and it should see my other Exchange servers. Do I need to do anything else? I only have one Administrative Group and I only really want to end up with one. Do I need a routing group connector? I am not going to be modifying my MX records since we have a spam filtering appliance, the box in the branch office is just going to host mailboxes, everything will still go in/out through our main office. What if anything should I be looking out for with this configuration. Any advice is appreciated.
