I am looking at migrating to Exchange 2007. Right now, there is one Exchange 2007 server in place that is configured as a Hub Transport and CAS server. It appears to be what is sending/receiving mail as the connectors are setup with lower costs than the connectors on our main 2003 box. I cant configure the default recipient policy as it wants me to do it on the 2007 box. However, when I troubleshoot mail issues, the only place I see the queue's is on the 2003 box?? How do I know the mail is going through the 2007 box? when I look at the queue viewer or message tracker in 2007 I dont see anything. Forgive me being new to this, but I want to make sure this is functioning as is before I put in the new 2007 mailbox server.
