SMTP TLS Cannot open a socket

I am setting up our SMTP connection on the Nessus Manager virtual appliance.  I want to use encrypted email using TLS and when I setup our mail server host and port it states it cannot open a socket on port 465.  I could only do a packet capture with the virtual appliance and it looks like packets are sent and received.  The exchange group says our settings are correct but the server can't open a socket.  Is this an issue anyone else has encountered or does anyone have an idea what could be the issue?  There are no firewalls that exits between the two servers as they are both internal.
