I have Exchange 2007 running in a mixed 2003/2000 windows domain. The mode is set to 2000 native. There is a co-existing Exchange 2000 server running concurrently with the Exchange 2007 server. When a desktop is pointing to the Exchange 2007 server, it cannot send outgoing mail. For those users whose mailboxes are on the Ex 2000, incoming and outgoing work fine. I can receive mail from the internet and from the local network just fine, but i cannot send out going mail to internet recipients. I set up an outbound mail connector but I'm not sure that that's done right. Can someone help me troubleshoot?
Really need to get this address ASAP. Thanks a lot in advance.
