I have setup a new 2007 Exchnage on 2007 Server and I wish to create a connector so that mailboxes for the same domain can exist on either system. The mailboxes and active directory seems fine and I can move mailboxes from one to another but no mail flows from either server to the other.

I have folllowed the instructions above and I have a connector showing in the Exchnage Management Shell (Get-RoutingGroupConnector)

Name SourceRoutingGroup TargetRoutingGroup
---- ------------------ ------------------
Interop RGC Exchange Routing Group ... First Routing Group
Interop RGC First Routing Group Exchange Routing Group ...


And also on the 2003 server I see the routing groups (although I cannot edit view properties as it says System Manager 8.0.30535.0 is required)

Additionally the queues of the 2007 server are not viewable on the 2003 manager. It simply shows them as state Not Available.

Can anyone shed any light on how I might solve this?

I'm having the same problem.

Emails flow from 2007 to 2003 but not from 2003 to 2007.

On my ex 2003 server the queue says "The connection was dropped by the remote host."

This is leading me to think its permissions on the 2007 server but how to I set these?.

I can see the exchange routing groups for both 2003 and 2007 and can move mailboxes but I can'd send or recieve any email on my 2007 box. Is there something additional that I need to set up?

Has anyone got a solution to this problem yet? I have been having the same problem and it seemed to start after Exchange 2007 SP1 was installed. It is hard to say exactly as I rebuilt from scratch and added SP1.

Sometimes the basics get missed.
When I installed Exchange 2007 I could receive mail into a 2007 mailbox but not send out from it.
Turns out I had 2 problems:
Since I installed EX07 on Server 2008, my AntiVirus exclusions to allow use of port 25 were not applying. Simple test for this: Try to use telnet to get to your Exchange 2000 or 2003 server. if you cannot connect port 25 is probably blocked.

Then if you can get to Exchange 2000/2003 mailboxes but not out to the Internet, make sure your Exchange 2000/2003 Internet outbound connector is set up to accept mail from the Entire Organization rather than just its own routing group (Address Space tab - Connector Scope)

These two steps solved all my mail flow issues
