I upgraded one of my Macs to OS X Mountain Lion. Today, I found out, that iCal communication has changed. I cannot enter nor modify calendar entries which are hosted on a Zimbra server (Zimbra Community Edition 7.2.0) and accessed through the CalDAV protocol. - The same calendar can be updated from a 10.7 OS X Client without any problem for the same account.


So it seems that Mountain Lion changed the way of its communication to CalDAV servers. I get the following error message in iCal: The server responded with “400” to operation CalDAVWriteEntityQueueableOperation.


I did not expect iCal to become broken through the Mountain Lion upgrade... - Any idea if this can be fixed?

Mac mini (Mid 2011), OS X Mountain Lion
