I try to use the iSync connector between Zimbra 4.5 (Network) and MacOS X 10.4.8.
There are several issues, top among them is that the "ATTENDEE" field appears to be dropped on the Zimbra side, without warning!
- The sync has self-consistency trouble
- upon init: after the initial upload of calendar data, Zimbra sync still wants to do modifications at an immediately following manual sync
- when another client is involved (say, Work and Home), it takes several manual sync cycles on either side to achieve self-consistency.
- after sync, all events are "STATUS:CONFIRMED"?
Now, the RFC2445 has "ATTENDEE" as a regular field. The entry also mentions "Non-standard", which means that the field may hold non-standard properties, but "CN" (Common name + email) is definitely standard. However, the RFC section also says:
How would Zimbra tell the difference between a published and a private calendar (which is what I'd need)This property MUST NOT be specified in an iCalendar object when publishing the calendar information (e.g., NOT in an iCalendar object that specifies the publication of a calendar user's busy time, event, to-do or journal).
