I've searched the forums/bugs and not seen this, anyone have more information/ideas?
Groupwise user sends ical compliant message to me.
shows up in inbox, I accept the appointment
item shows up in my calendar on the webclient (I only have one calendar)
It never syncs (activesync OTA) to my mobile device (WM5).
If I add an item manually to the calendar it syncs right up, if another user on zimbra sends me an appointment and I accept it syncs right up.
I've tested this several times, with the same result, and this is a BIG deal as we are trying to migrate from groupwise to zimbra.
