How can I do that?

The Lync client can only use TLS connections, this behavior is not configurable (greyed out bydefault). Open Lync client>>Tools>>Options>>Personal>>Advanced>>Bydefault it uses the automatic configuration which is TLS (under connect using "TLS").

Hope this helps :)

the iiscrypto tool is handy to surface the overall crypto used as it grab directly from the machine registry SChannel setting (which Windows depends on)
- you can even use it to disable and enable as required and desired for lockdown. in fact, the Lync client (at least on 2010)  can only use TLS connections, this behavior is not configurable.
