Kontact-> adding Calender, but how?

Hi there, same as in my other Email, i'm trying to add our Exchange
Calender.
Normally i add the ressource at the Point for Email-Setup and check there
all menues, so also for calender, but in my calendar, there are no entries
(and there are a lot of).
How to handle this?

Is KDE-Pim not ready to work with full integration for exchange?

Sebastian
