Hi,
You know that if the CAS and MBX servers are collocated on the same server the SMTP Receive connection for the Transport service will listen on 2525 instead of 25, well, because of a requirement, I separated this roles on two servers, so I needed now, that the "DEFAULT FRONTEND Servername" that listened on 2525 to listen on 25, So I changed it (remember, CAS is not present anymore on this server), but mail is stuck on draft folders and if I see logs:
Error encountered while communicating with primary target IP address: "421 4.2.1 Unable to connect." Attempted
failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 10.2.x.x:2525]}
StoreDriver still wants to send email to 2525 instead of the updated 25 of the receive connector.
I restarted Mail Submission, Information Store, and Transport Services with no luck.
Where is Exchange reading this "old" config?
Many thanks
