I upgraded to Lion yesterday and now I have a severe problem with the sync of ical with our Zimbra server.

I use the Zimbra iSync Connector 6.0.2495.

The problem is, that nearly most of the times when I start ical, the sync starts and when it's finished, it starts all over again but with a new duplicated account! So right now I have approximately 30-40 duplicates of my account... The ical application doesn't react any more now...

Does anybody have the same problem (and perhaps solved it)?

Until the upgrade everything worked fine. I reconfigured the account already and for a short time it worked, but now it goes berzerk again...

Best regards,
