I'm in the same boat, ePO cannot send email. it's kind of sad/hilarious for a security company that their flagship security product doesn't have an option to send email securely.
And how do You with Exchange connector can tell ePO send messages with TLS? I'm sure that You messages and password are sent in Plain text format. Run for example wireshark an You can view Your user and password.
you are correct, I did not mean that we fixed the issue - just that we gave up and resorted to allowing the ePO server to send e-mails in plain text with a limited user account - aware that the credentials would go over over the wire in plain text.
the product still needs to be fixed to allow emails secured by TLS. We just decided the risk was sufficiently low in our case to allow this one exception.
