yesterday I updated from 5.0.18 to 6.0 (Network Edition) and now the calendar sync with iCal doesn't work anymore. In fact, all formerly shared calendars disappeared from iCal while they are still there in the Zimbra web frontend.
I went to the management console and made sure caldav is activated, but that didn't change anything. Anyone had similar experience?
Remember, I do not use the iSync connector but only caldav in iCal. Server is Mac OS Tiger, client OS Leopard.
