Calendar Server Reported Error: Operation CalDAVAccountRefreshQueueableOperation
I have setup several Users on a MAC OS X Server Lion with the sole purpose to use their Calendar and Addressbook as repository for calendar and address information for the Mac, Macbook and iPhone and shared calendars for all users of the OD. This worked quite well for a time. It seems to have stopped working a while ago (noone realised it because the individual device did not show an obvious problem and had all the required dates), definitively after the Update to 10.7.2, but presumably a couple of weeks before. To my knowledge I did not change anything beyond applying the apple updates.
One of the clients shows the dates of a shared calendar multiple times (depending on date up to 7 times, but mostly 3 times), the mobile devices and the other iMac only once.
Upon looking at the calendars (even as Admin on the Mac Server itself) the error message displayed is
Calendar Server Reported Error
Operation CalDAVAccountRefreshQueueableOperation
I hope there is a solution as we lost qiute a few dates on the iPhones during update to iOS 5 (the shared calendar data are apparently not backed-up).
