Merging together two exchange sites! Part 2

Thanks "onehump"
The sites are in different organisations.  I want to maintain the current hardware/software setup and so keep the local users mailboxes on each exchange server.  I want the new .com email feed to come in at the uk site, be validated against the local users and if not there be routed to the server in the states for delivery there.
Could this be done without merging the organisations by configuring a trust between the servers and configuring some kind of routing connector?
Would the only way my global address list give me all the uk and usa users is by merging organisations?

Thanks,

Mike

How did this get created as a new request?  :)

You can do what you need to do.  You simply setup the MX record for the new .com address to point to the UK server.  You configure the recipient policy (Exchange 2000, right?) on the UK server by unchecking the box that says "This Exchange Organization is responsible for all mail delivery to this address" which is found by editing the email address in the appropriate recipient policy.  You then create an SMTP connector to the other site with an addres space that matches that new domain.  I would make sure the recipient policy box above is CHECKED on the second org, otherwise you'll loop.

So... what will happen is that inbound email to that domain will hit the UK server.  The UK server will try to resolve it to a local mailbox.  If it cannot, it will pass it to the connector for delivery to the second org.  If the second org can resolve it to a local mailbox, it will deliver it.  If not, it will NDR it.  If you have the recipient policy checkbox I reference above unchecked on BOTH orgs, the second org would pass it back to the first and create a nasty loop.

If you want these orgs to operate as one organization, your best value will be to do the work to merge these two orgs into one.

Please keep this your replies in this thread because I get confused and don't have access to all info.  :)

Hi "onehump"

The server in the UK is 5.5 so I dont have the recipient policy option there, so I guess I set the new .com address in the IMS routing box, is there anything else you can think of here? Then the smtp connector would have to be configured from the ex2k in the states. I would then add the uk5.5 site in the "connected routing group" but then what would I need selecting on the "address space" page - connector scope , routing group or entire organisation?

Thank you very much for your help so far!

You could still do it with a 5.5 server.  You set the domain in the routing tab of the IMC to route email for that domain to the other server.  Local mailboxes will still resolve.  Create an new IMC instead of SMTP connector to the U.S. with the address space defined there.  The rest is the same.  Scope doesnt matter unless you have multiple sites/routing groups in each org.

Hi again.

When a new IMC is created do I have to have a corresponding SMTP connector on the ex2k server and also would I need to set up a trust between the NT and w2k?
Sorry if I am a bit dim!!

Not necessarily.  You only need one IMC going to E2K unless you want email to go from E2K to 5.5, in which case you'll need an SMTP connector going back.

Think of a connector as a one way connection to get email to the target bridgehead.  You only need one coming back if you want email coming back.  One case where you might want this is to get NDRs back.  :)
