Hello. I'm not sure what steps I've missed setting this up, but currently POP3 and IMAP are listeining on the correct ports and have a certificate assigned to them (it's a wildcard certificate). When I try to setup my mail client with either of these services, it just says that the server does not support the connection encryption type specified and errors out immediately. Both POP3 and IMAP are configured to use SecureLogin as the LoginType. An error with event ID 1102 is logged in the event viewer. The POP service failed to connect using SSL or TLS encryption. A valid certificate is not configured to respond to SSL/TLS connections. Check the configured hostname as well as which certificates are installed in the Personal Certificates store of the Computer. OWA works fine with the certificate. Any suggestions?
