Outlook certificate to send SMS

I am trying to add SMS functionality to Outlook to make a notfication system (e-mail and SMS.) I got an idea from this page http://www.sms-integration.com/setup...k-2007-84.html It seems great.
Outlook Mobile Services makes it possible to create and send SMS messages in Outlook.

I can use OMS only over HTTPS (encrypted) channel. I can create a self-signed certificate with the use of makecert program.

To create a self-signed certificate Ineed mkcert script. Is it correct if I type one of the following commands into Command Prompt?
mkcert <IP address>

or
mkcert <FQDN>

Have you done this before? Will it work?

Regards,
