"The server responded with an error" when modifying or deleting an item
I can't modify or edit an item in my MobileMe syncronized calendar. I can move the item to a different date or time, but if I try to delete it or remove an attendee, I get the following error:
The server responded with an error.
The request for “***” in “Calendar” in account ***.***@me.com” failed.
The server responded with
“500”
to operation CalDAVWriteEntityQueueableOperation.
I can't delete the item, or remove attendees from me.com either.
If I create another appointment, I can delete it, so I suspect it has something to do with the fact that I have invited attendees.
Any suggestions?
