I'm using a Mac with OS 10.6.4, ZCS 6.0.4 and Zimbra Desktop 1.0.4

When I use a browser to access my Zimbra data, I can see the calendar entries. (also the calendars on my machines are syncing thru Zimbra without any problem).

But when I use Zimbra Desktop, the calendar entries do not appear. Emails are shown fine in ZD, only the calendar data does not appear.

What could be the problem ?

Thanks for helping me out here,
