Probably a simple question but I am missing it.
I have a Zimbra account and I just installed the desktop version. I am trying to set it up but I have no idea what the Incoming Mail Server should be? What do I put there if I am using a Zimbra Account?

And speaking of that since I am using a Zimbra Account and it is Zimbra Desktop why doesn't it automatically sync?

I see there are problems using XP. I have XP have those issues been resolved or am I wasting my time?
