I'm a new Zimbra desktop (at least trying to find something more "corporate" than Thunderbird) but from what I understand Zimbra Desktop doesn't support Caldav. Am I right? How is that possible? It does support gmail, which is caldav, yahoo! which is caldav and Zimbra, which is also caldav but no "regular" and standard caldav.

I there a workaround? Can I configured a plain caldav account?

Thanks
