Exchange 2010 Server.

Does anyone know how to confirm the version of TLS that an Exchange 2010 server is using to communincate with a smart host

Wireshark should show this I would think.

Yes sir I had that thought but I was advise that their is an easier method perhaps registry setting or somewhere is the Exchange configuration software.

In the past I have used the following tool to fetch the data:

Alternatively, you can validate manually what's enabled:

In the Exchange 2013 SMTP outbound to smarthost logs, I see the following entries:
>,STARTTLS,
<,220 please start a TLS connection
Check if Exchange 2010 has "verbose" logging level configured on the connector.
