Both server certificate and exchange certificate are valid. OUTBOUND emails that leave our exchange server and go through the SEA work and negotiate TLS correctly. Also, INBOUND emails from Exchange Online Protection to the SEA are negotiated and encrypted correctly. INBOUND emails that come to the SEA and are sent to the Exchange server can’t negotiate TLS.
TLS library problem: 62534:error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol:/build/src/secure/lib/libssl/../../../crypto/openssl/ssl/s23_clnt.c:726:
Any ideas/thoughts?
