I have two Exchange 2003 servers and I would like to route inbound and outbound email to go through the CAS server. How do I do this?

[Ossian]

Add the hub transport role to the CAS server and create appropriate send and recieve connectors.
(What are your roles on both servers at the moment?)

I assume you are part way through a migration? As Ossian states it is the Hub Transport role that deals with the mail flow.
You will need to setup a new send connector on the Exchange 2007 HT so it can send email to the internet (2007 mailboxes should now use that) then remove the internet SMTP connector on your 2003 server (if you have one). 2003 will now send mail to the HT which will then send it out.


The first bit of this is worth a read:

Also check you have your routing group connector setup to allow mail flow between 2003 and 2007.

Sorry I should have stated that I have HT and CAS on the same server. I have set up a new send connector on Exchange 2007 HT and I noticed that I also do have an Internet SMTP connector on the 2003 server.

So once I remove the Internet SMTP connector from the 2003 server, all mail will be routed from 2003 to HT and then send it out on the internet?

Will I need to restart any services? Will I be able to track messages from the CAS/HT server?

Thanks.

Yes. If you leave it on the 2003 then user mailboxes on there will go out using it. The 2007 mailboxes will go out using the one you setup on the HT.

Eventually you will delete or change the cost of the 2003 one so all mail goes out the 2007. You will probably not have any mailboxes left on it by then anyway though.

I'm pretty sure you don't need to restart any services.

Make sure you can send email between the two servers internally. If not check the smtp virtual server doesn't have a smarthost added as well because this will stop it.

Currently we dont' have any 2007 mailboxes but when we do, the 2007 mailboxes will go through the HT?

What does the cost do?? Is it s priority setting??

So if I delete the Internet connector on the Exchange 2003 server, the changes should occur immediately?

Is there anyway to check this?

How do I configure HT so all emails comes into the server?

I also check both default SMTP virtual server on the exchange 2003 server, neither of them have smarthosts.
