1. Windows Server 2003 R2 Standard SP2 w/ Exchange 2003 SP2
2. Windows Server 2008 Standard x64 SP2 w/ Exchange 2007 SP2
- Installation logs for Exchange 2007 show successful installation.
- Can send mail from Exchange 2007 to Exchange 2003 users
- Can send mail from Exchange 2007 to Internet
- Routing connectors were created for both sides during install; for my own sanity, I removed and recreated routing connectors via Exchange 2007 EMS
- Can telnet from Exchange 2003 to Exchange 2007; mail is delivered without error
- smart host is NOT configured in SMTP virtual directory
- ADSIEDIT shows correct permissions set for each administrative group (according to this link: https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_24557328.html?sfQueryTermInfo=1+2003+2007+destin+exchang+mail+queue+unreach
- Ran Best Practices and Troubleshooter on both servers; both tell me message are in the queue and that routes between them 'may not be available' (obvious??)
- Windows Firewall is disable on both servers
- No Event Viewer errors on either server
- Exchange 2007 has 2 receive connectors: Client and Default. One is configured for port 587 and other is configured for port 25. Permission for port 25: anon, exchange servers, legacy exchange servers
Any ideas where to go from here?
