Please advice, thanks.

Because all Exchange 2003 (included Front End) will be decommitted after complete migration.
Check for routing connector is still there....between e2k3 to e2k10
run get-routinggroupconnector
You need to create a send connector on Exchange 2010. This is happening probably you have a SMTP connector on your Exchange 2003 FE.


Check this to create send connector.
