How to use Comodo certificate in Windows Live Mail?

I just installed the COMODO digital signing and encryption certificate for use in Windows Live Mail. What do I need to communicate to the person I send a signed/encrypted email to allow them to open and read it.

Hi

The answer to your question, and any others, can be found in the e-mail certificate knowledge base.
