So, up until oh.. today our office was getting along just fine and dandy with iCal. People were syncing on mobile devices, on their desktops, laptops and so forth. Mostly Snow Leopard, by the way, and one user who had already upgraded to Lion. Things had been working just fine, again, up until now.
The error reported back on the user's Macbook Pro is this: The request (CalDAVAccountRefreshQueuableOperation) for account "so and so" failed.
2/14/12 2:53:49.340 PM iCal: Account refresh failed with error: Error Domain=CoreDAVErrorDomainCode=3 "The operation couldn't be completed. (CoreDAVErrorDomain error 3.)" UserInfo=0x7ff03437b530 (AccountName=soandso, CalDAVErrFromRefresh=YES}
Things I've tried:
Deleted said account from iCal preferences, and added it again. Dumped and rebuilt CalendarCache, also the main iCal plist file.
Ran disk permission verification and repair.
Updated to 10.7.3 just to see if that would also help as well.
Seems to be only with this laptop with Lion that it's happening as every other computer/user is having no issue.
