Exchange 2003 to 2007 Connector - 2 way?

[GeorgeTuk]

Hi guys,

Have recently upgraded to Exchange 2007 and moved the majority of the mailboxes, however I would really like to change the MX Record to point to the new IP for a couple of reliability reasons.

If I do this will the mail still flow to the mailboxes on the old Exchange through the connector or is it a one way deal?

Thanks for any help in advance.

George

What happens when you telnet to the new server over port 25 and send mail to a user on the old server?

Mail does already flow from the old server (serving as a bridgehead) to the new Exchange 2007 server so thats ok. So I wondered if it would work the other way around if I pointed the MX Record to the new server?

I know the new Exchange 2007 can receive mail from other MX records, I would just like to repoint the MX Record.

Please see my original response. Doing that will validate whether it will work or not.

Check the send connectors, verify internal 2003 to 2007 and back again works then for completeness, do a telnet session to 2007 with an email to a 2003 user.

Basically I've just suggested doing exactly what Pat suggested. His way is the right way...
