I have two exch2013 CU8 servers and we use IMAP for one service. We are running into an issue with one of the two servers. If I point the IMAP connection at exch01's IP address it works fine. If I point the same setup to Exch02's IP address it fails and I have no idea why.
The services are started on both servers and the default ports are being used for the IMAP connectivity. What else could stop IMAP from functioning.
I enabled protocol logging and i do not think i am seeing anything show up in the logs from the test connection. There are only entries for a healthmailbox in there.
The Windows firewall is currently turned off and there is no additional AV / Firewall services that could interfere with the inbound connection.
