Exchange 2003 to Exchange 2007 connection help.
Posted on 2009-04-17
Current setup: Spam filtering service that filters our inbound and outbound email and sends/receives directly to our exchange 2003 server. We purchased a new server with exchange 2007 to be housed in a different office and to be used by the people in that office. Outlook is getting slow for this office going over a site to site VPN. I installed Exchange 2007 and had issues with email outside our domain. After changing a lot of settings aI wasn't comfortable with I ended up doing a full reinstall of Windows and Exchange 2007. When the installation was complete exchange had configured itself into a loop from the first install of exchange that i never removed from our exchange 2003 server. So internal mail was working but any outside mail was being bounced between the 2 servers. I was able to fix it by deleting the connector on the exchange 2003 server that was configured to point to the exchange 2007 server.
So now my exch2003 box is functioning like it was and the exch2007 is unused. I set up a mailbox to test it and now I can send out but not internally and I can't receive from either. Under the exch2007 send connectors there are 2 configured. The first is configured to send to our external spam filtering server and the second is configured to send to our exch2003 server.
So can anyone shed some light on how this should be configured? We want all the users to use the exchange server in their respective office to keep that traffic off the VPN.
