I though I had TLS enabled; however when I telnet to the exchange 2007 server to check, I get:

"250-STARTTLS" is missing. How do I add this option so that opportunistic TLS is enabled?

Thanks in advance!

Had to run

Enable-ExchangeCertificate -thumprint <thumbprint of certificate> -services:SMTP

Which enabled the STARTTLS on the exchange 2007 server.

Now on to a client authentication in TLS issue, which will be in a different post.

Cert info along with thumbprints can be viewed with the get-exchangecertificate command. (Not 100% on the syntax of the command, but it's been discussed at length in other posts.) Refer to this one:
