I have an organization with a Standard 2003 Exchange server. It is dying a slow death, so we installed an Exchange 2003 Enterprise server. Everything is running fine....EXCEPT...
Both servers are back-end at the moment, we cannot add a third for migration. If we move a mailbox from the old to the new, they can send and receive email from inhouse and from outside, BUT...
This client was recently acquired and they have an IPSEC tunnel going to the mother corporation. Anyone on the old server can send email and it is received by acme.com (name is changed to not question the guilty). This NEW server has messages stacked up in its queue when trying to send to acme.com. I figured it might be firewall or access rules on their side (which SHOULD have been opened but you know Fortune 500 companies take 1-50 weeks to actually IMPLEMENT something). So I created an SMTP connector with a lower value than the * address space to point any email for acme.com to the old server ONLY as a bridgehead server. It keeps timing out on the new Exchange server queue as "remote server did not respond to the connection attempt."
Anything else I can do? I can't really make the old server the front end server for now because people won't be able to access their email correctly.
