First let me start with: I have read every post in EE and also googled till I can google no more about my problem.
Here is the environment:
Windows 2003 Domain with SP1 (from Day 1)
Exchange 2003 Enterprise w/OWA enable with forms with SP2 (from Day 1)
New Exchange 2003 Standard with SP2 (just installed last week)
We are not using a Front End Exchange Server
We installed the new Exchange server in the same domain as our other Exchange server and is located in the same building and same network. We have no smart host entries in either Exchange SMTP Advanced Tab (seen this posted a lot as a major cause.).
You can telnet between the servers using:
telnet SERVERNAME 25
telnet IP 25
telnet FQDM 25
The new Exchange will route email to the old Exchange where all other users are located (except my test I have on the new one) and also out of the network as it should. But the old Exchange will not route email to the new Exchange (where I have the one test mailbox).
When I move the mailbox back to the old server, it works great. When I move it to the new server, it doesn't receive any email.
The SMTP Queue of the old server does show email ready to be delivered to the new server, yet it just sits in the SMTP queue.
Here is one catch: I can restart the server and as soon as it is up, it will release the email to the new Exchange server that it is currently holding (which made me happy the first time it did it thinking I solved it.) Then if you send another email to that mailbox user on the new Exchange server, the email again will sit in the STMP queue (restarting the server every minute possibly isn't the best solution, ha, ha!).
Both servers are in the same routing group. The orginal server is listed as Master and the new one is listed as Member.
Can some please help me figure out why the old Exchange 2003 server will not route email to the new Exchange 2003 server? What could I be missing?
