Exchange problem on all my Apple stuff

[pjkeyzer]

I'm not sure if this is the right forum, since I don't know where the problem lies. I experienced it on my iPhone, iPad, and laptop in iCal, but my Outlook calendar at work looks perfectly normal.

Last week, I had a meeting request change at the last minute, and the update was sent. Outlook received it fine, but on all my Apple devices, the event is duplicated about 100 times, but the end date of all of them is in September (it's a 1 hour meeting that ended last week, so I don't know where the September date came from). Does anyone know how to get rid of these duplicate events without sending 100 "event declined" messages to the organizer of the event?

Thanks

Did you try resetting your ActiveSync connection? Same thing for your other Exchange connections (which use EWS). As long as they don't exist in Exchange/Outlook it shouldn't sync back.
