Zimbra Desktop - loading certificates?

[bknoth]

I can't figure out how to have Zimbra Desktop use certicates. How do I install my corporate certifcate so I can access a certificate-protected calendar?

I must be missing something basic here, but I've checked the FAQ and searched docs to no avail.

install the certificate on the server and
configure ZD to use https

What do you mean by "configure ZD to use https"? I don't see that option for calendars. I just see SSL options for mail.

Also, I don't control my server. That's a corporate function. I'd like to use the certificate that was issued to me to identify myself to our corporate calendar server (which is a Zimbra server).
