Exchange Server 2003, SBS 2003. Sorry about the vague title, I'm not really sure what the proper terms for the issue I'm having are. There is an office that is part of a larger organization with their offices overseas. This local office gets their mail from the external server using the POP3 connector. The local users then access their mail from the exchange server with outlook, and all is hunky dory. The issue arises when one of the local users sends an email to another account in the same domain that is accessed both by a local user, AND by a user overseas. For example, they want to send to recipient1@mydomain.com, but recipient1 is a local mailbox pulling mail from the POP3 connector. So the message gets to the exchange server which is like "ah, this is a local user" and delivers the message to the mailbox. Local user sees it, but external user cannot. What I need it to do is to send the message out to the external mail server, so the user overseas can see it, and then the pop3 connector can pull the message back down to the local server for the local user to be able to see it as well. I'm guessing this is a fairly simple thing, but I'm probably drawing a blank on my searches because I don't know the proper terminology for this issue. Any help would be much appreciated.

You might want to post this in the SBS Forum: http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads The POP3 Connector is an SBS component, not Exchange. POP3 is a single mailbox client mail retrieval protocol, not a mail transport protocol. Any attempt to use it as a mail transport protocol is a great big kludge. Exchange is designed to connect to the Internet using SMTP. Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

You are sharing the SMTP address space. You need to configure Exchange to share the SMTP address space. http://support.microsoft.com/kb/321721 Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Thanks Sembee, I knew it would just be a matter of knowing the proper terminology for this.
