I followed the directions for a transition from 2003 to 2007 found here (http://exchangeserverinfo.com/2007/12/04/transition-from-exchange-2003-to-exchange-2007.aspx).  I've moved one mailbox (mine) from the 2003 server to the 2007 server.  So far everything works except sending mail externally and accessing owa externally.  When I check under Organization Config and Hub Transport, I only see one connector (AOL.com) which I'm not sure I understand.  I thought there would be a connector from 2003 to 2007.  So, I need help setting up this connector but don't want to decommission the 2003 server just yet either.  Ideally I'd like to move the mailboxes over a few at a time and be able to get and receive email on both.  But, I've come to the conclusion that if I can get my mailbox moved and working I'll do the rest ASAP.  I should also point out that I plan to change the internal IP of the 2003 to the 2007 so I won't have to change any of the MX records (right?) and that would make the OWA (I know it's not called that anymore) work, correct? can someone help with the smtp connector? Also, do I have the right idea with just changing internal IPs and doing all the mailboxes at once (about 150 or so)? Everything would work that way right?

Thanks in advance for the help.

Thank you FNM.  This information is helpful but doesn't answer the full question.  I found this link on my own (along with many others) but am concerned if I set it up that I'll partially disrupt the organization.

You should have a routing group connector, which Exchange 2007 GUI cannot see. You should see it on Exchange 2003 ESM.
However whether you have an SMTP connector or not depends on many things.
Are you currently using a smart host? If so, then that should be set on an SMTP Connector, not on the SMTP virtual server.

Were you trying to send to AOL?

As a matter of course, I always create an SMTP connector on all Exchange 2003 servers I work on. If I am doing an Exchange 2003 to 2007 migration where one does not exist, then I will create one. Exchange 2007 will see that as a Send Connector it cannot modify, and it ensures that email flow continues to operate correctly.

If you are concerned then I would suggest that you create an SMTP Connector on the Exchange 2003 server, even if it is set to use DSN with the Address Space set as *. Set only the Exchange 2003 server as the bridgehead and set the scope to Entire Org. Then all email will go out through the Exchange 2003 server.
