I'm trying to get StartTLS enabled on my Exchange 2010 on Windows 2008R2
I have followed the steps in this link:
Locally, when I telnet to 25 and type "ehlo", I see STARTTLS listed.
Externally, when I do the same, STARTTLS is not listed.
I don't see any Event Viewer entries to show any errors.
I've read it possibly a firewall issue. My Cisco engineer looked at the ASA and didn't see anything. Even followed this link
which I found from here:
There is only one SSL Certificate which all services are using. It was purchased from SSLS.com
What step am I missing?
