Removing Exchange 5.5 server from Organization 1

[eastbr]

Completeing a migration from Exchange 5.5 to Exchange 2003.
I have moved all the mailboxes and homed the public folders on the E2K3 server. Everything is working perfectly except outbound email is still using the 5.5 server.

What steps do I need to take switch email over to use the default 2K3 virtual smtp connector?

The new SMTP connector will need a lower cost than the old one. When mail stops flowing through the old one, remove it.

Thanks for your response.

If I remove the Internet Mail connector on the Exchange 5.5 computer. Will outgoing mail automatically start using the E2K3 smtp virtual server, or this there more configuration I have to do to make it work?

Thanks,
Brent

If you have more than one smtp connector, mail will flow out the connector with the lowest cost. This is why you want to stand up the new connector and give it a lower cost first. Once you verify that mail is indeed flowing through the new connector, you can safely remove the old one.

Where, how do I give the E2K3 connector the lowest cost?
How do I verify afterwards that outbound email is indeed using the E2K3 connector?

Thanks

1. On the properties of the connector under your address space.

2. Check your internet mail headers on a recieved message, or simply watch your queues.

I made the config change, but now email just collects in the E2K3 Internet mail queue. I changed the Internet static IP to point to the E2K3 box.
Any thoughts?

If it collects in the queue, you might want to check your firewall rules. Are you allowing the E2K3 box to go outbound on port 25?

You were right about the firewall access list rule not being setup. I mapped the external IP to the internal one,
but forgot to add an access list to allow outbound SMTP for the E2K3 server. Mail is flowing through the E2K3 server now.

Thanks for your help,
