Hi guys,

Am new to exchange and have been tasked to upgrade from 2003 to 2010.

Have setup a new vm for this and have installed exchange 2010 int coexistance. I have moved a test maibox to the 2010 server and the move went ok but now that mailbox is isolated and cant send or receive.

I think it has to do with the way we have our mail setup.

The mail flows to a server which is host the software mailmarshal and when it is filtered by that it's sent to the 2003 sever from there i thought it would be routed to the 2010 server for the mail boxes that are on there.

Is this an out the box setup? If not an i setup my servers to run this way till i can decommission the 2003 server?

During the setup you will be asked for a bridge-head server which is your Exchange 2003 server. This will create a routinggroup connector which is responsible for sending messages between both organizations.

Exchange 2010 will use the Exchange 2003 environment to send mail to the internet.

So first check if you can telnet in both directions and can connect to port 25, for example:

telnet servername.domain.local 25

What you could do is recreate the routinggroup connector by using the Exchange Management shell:

first remove the current:


then create the new one:

New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Ex2010.domain.local" -TargetTransportServers "Ex2003.domain.local" -Cost 100 -Bidirectional $true

Then check if it works OK.



Best regards,
