ICal Old events sometimes keep sending for acceptance.

iCal events will sometimes keep being sent out, even if the event has already taken place, and even if you accept it multiple times. They will keep being sent out until you delete the event.

The enviroment is Exchange 2010. Mac Mail, iCal and Contacts applications are used.

The 2 peoples Calendars who seem to be sending out the event messages appear to have delagates sending out the events for them.

This does not happen on all events, only a small few. No pattern to make the issue accure. It happens so far on 2 different users calendars.

I have never seen this before.

Thanks,

Tommy
