There's an event ID that's part of the iCal. I'm not sure how deletes are handled - if it's still part of the iCal but with a status of "delete" or if it's up to the receiver to scrub everything that came from a prior iCal but not part of the current one.lleach4 wrote:So the calendars were communicating about the event and recognized it as the same one even though they showed it on different dates.
I assume you're checking your Calendar via a browser. Any chance this could be a browser caching issue?
