iSync and CalDAV errors with iCal - CalDAVAccountRefreshQueueableOperation
Wondering if somebody can help me with this. We have a customer who is suffering a problem on one of our Zimbra servers. The server is bang up to date: Version 5.0.13_GA_2792.RHEL4.NETWORK 6 Feb 2009 and they are using the latest version of the connector that comes with this server version.
The problem is that in iCal after setting up an account in the Zimbra connector (and so creating a CalDAV account) it will perform an initial sync, but then a little warning sign will show up next to the CalDAV account in iCal. When you click on it you get an error. These errors can differ, so I have attached all three of the different ones I saw.
I did some searching and some people around the net seem to suggest that CalDAVAccountRefreshQueueableOperation is not unique to Zimbra, but rather might be associated with iCal and how it handles CalDAV. All the same I thought I best check to see if anyone has any ideas why this is happening, and potential fixes? We have many Zimbra servers and I have not seen this reported on any of the others, so this leads me to believe it may be a server related issue?
