In the FAQs for the latest 0.87 release, it indicates that Shared Calendars will "soon" be available. I have also found that the Beta version 1.5 still does not support syncing Shared Calendars. And in a post on 01/19/2012, Cine indicates that "the Android Calendar application only synchronizes the main calendar" and that "[They] are currently trying to find a workaround for this, but being a limit imposed by the operating system I can't give any ETA on a solution"
Has there been any progress on this feature? Will this be a feature released in the 1.6 version?
Syncing a shared calendar to a Mobile device is the only thing holding me back from installing Zimbra and the ZeXtras Suite. I would very much like to see this feature.
