Hello,

I have a ZD 7.1.2 (and 7.1.4) installation connected to a 7.1.3 Zimbra Server.

2 users have a problem when connecting Zimbra Desktop to the server. It keeps showing the Sync icon, next to the user name in ZD. It tells me the status, it's still busy and the last sync is "never".

I don't see any problems in the ZD logs, however I found this on the server mailbox.log:

How can I find out what calendar item is bugged and needs to be deleted in order to fix the sync? What could cause this sync problem?

I checked for returning events and deleted them, so there are no "endless" calendar events anymore.
