We have a Exchange 2003 server in production, we installed Exchange 2007 along side it because we want to migrate over to Exchange '07 and decommission '03. I can send email from a test user account, it reaches '03 mail boxes and externally (my gmail acct), but nothing reaches the '07 server when I reply to the test user account, it may be my routing group connector, but I believe it's correct, I have attached a .jpg of the routing group connector configuration in powershell, "municode" is Exchange 2003 and "Exchange Routing Group..." is Exchange 2007.
One other thing that looks wrong to me is that when I go into the System Manager on the Exchange 2003 server, go to Tools, Monitoring and Status, Status, it says MCC-MAIL-01(exchange 2007) and that Status is Unreachable, I have also included an attachment called "Status.jpg".
Other things you should know
-Exchange 2007 is a VMware virtual server on an ESX 3.5 U4 server
-I recreated the bi-directional routing group to Microsofts specs
Thank You Very Much, any help is much appreciated!!
