ok, the environ is a Windows Server 2003 Active Directory Domain. I have one Exchange 2003 box in the building. I just added a Server 2008 with Exchange 2010 server and I got it up and playing nicely with the Exchange 2003 box. During the install, it created a connector and seemed to set up the mail flow nicely. When I log into the new exchange 2010 server, I see all of my users and their mailboxes. Of course, their mailboxes are in the exchange 2003 server's database.
I created a local move request for one mailbox and moved it from the 2003 DB to the 2010 DB and it moved fine. I even changed my outlook to point to the new server and my exchange mailbox is opening fine off the new server.
the problem is I can't send mail from the new mail server, from the one mailbox I moved over. I feel like I'm missing something but I don't know what.
ideas? Do I need to go to me exchange 2003 box and add the IP of the new exchange server so that it can send out? I'm unsure where to start...
