Trying to install the desktop on Mac (latest OS and Zimbra) but it won't get past the settings screen. I access OWA all the time via browser and use Entourage to access Exchange IMAP daily, but no matter the port/ssl settings, it won't validate. I've had my tech (not a FanBoy of alternative betas by any stretch) look and he's stumped.

Ports have been varified, tried with and without ssl, nothing. I get timeouts and ssl failures depending on the port settings, but the right ones just come back with fails. It's strange that I can't even get it set-up without ssl at all.
