Exchange 2007 and 2003 Coexistence

Hi. I have installed Exchange 2007 (and SP1) into a simple 1 domain and 1
site organization, alongside an already existing Exch. 2003 server.
Everything seems ok, active directory is healthy (i.e. dcdiag and netdiag
yield perfect results), but I am stuck. After following the steps here:
"How to Install Exchange 2007 in an Existing Exchange Server 2003
Organization"
http://technet.microsoft.com/en-us/library/bb124350(EXCHG.80).aspx ...
I created a new user, who cannot send outside or inside. I see the default
routing group connectors in the 2007 and 2003 servers.
Do I need to run this command now?
"New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers
"Ex2007Hub1.contoso.com" -TargetTransportServers "Ex2003BH1.contoso.com"
-Cost 100 -Bidirectional $true -PublicFolderReferralsEnabled $true"
as found here...?

Thanks! I am afraid of the consequences on the live environment...

No need to run any cmdlet, it should be configure the RG automatically when
Exchange 2007 completes installation. Where is users mailbox located?

All employee mailboxes are on the 2003 server. But I created 1 new test user
on 2007, and that is the one that cannot sne/receive.

What errors or NDR is received back? When the 2007 mailbox user sends a
message is showing in the Queue?

Thanks for the help. This account CAN send to 2003 based accounts, but not
outside ND it cannot be sent to. The queue error for the outside test says:
Last Error: A matching connector cannot be found to route the external
recipient

I thought connectors to the existing 2003 server were created by default?
Maybe I did something wrong ...

RESOLVED!
Not sure what the cause was, but here is what I did: first, I deleted the
Exch 2007 based routing group connector, visible via the Exchange 2003 ESM.
[Do NOT delete any connectors based in your 2003 routing group]. I waited a
bit and then restarted the Exchange Active Directory Topology Service (which
restarts like 12 other Exchange services) on the Exchange 2007 server. This
was all ok to do in my case as there is only 1 test mailbox on it for now
although probably not needed...
I then studied the Exchange 2007 Help, after a search of the index for
"routing group". Then on the Exchange 2007 server I issued this command via
the Exchange PowerShell (first I mistakenly tried "-Bidirectional $false"
because I was afraid of the 2003 email server getting confused, but it does
not, and in my case bidirectional flow is needed as I need send AND receive
for the mailboxes on the 2007 Exch server):

---------
[PS] C:\Documents and Settings\Administrator.DOMAIN>New-RoutingGroupConnector
Name "M1 to M2" -SourceTransportServers "my2007mailer.domain.com"
-TargetTransportSerers "my2003mailer.domain.com" -Cost 1 -Bidirectional $true

Name SourceRoutingGroup TargetRoutingGroup
---- ------------------ ------------------
M1 to M2 Exchange Routing Group ... First Routing Group
M1 to M2 First Routing Group Exchange Routing Group
....

Exchange coexistence: coud I unstall E2K3 after installing E Hi, I'm in the process of determining potential issues for testing E2K7 in our production environment.
