Duplicate calendar entries for .ics subscribtions from Zimbra server


I am evaluating emClient for use with the corporate Zimbra server together with all my other accounts. It work just awesome except one pretty mean problem: appointments from Zimbra (calendar subscription using .ics format) duplicates some of the appointments on every refresh. Using “Repair” reset them but they start to duplicate with each refresh again. The appointments leading to this issues are invitations from other co-workers set to multiple participant where I am one of them.

Is this a known issue? Any workaround? Combine refresh with repair logic maybe? I could send you the .ics data.

Thanks for helping me,

I fixed it by attaching Zimbra as a CalDAV calendar instead a .ics calendar subscription. The problem with the group-appointments don’t seems to exists win CalDAV integration.
