Deleted recurring events are added and deleted a second time
Posted by - NA - on 29 June 2009 11:10 AM
This issue applies to a recurring event created on the server and then subsequently deleted for Exchange. 

The original addition and deletion of the event are synchronized to the device, but at midnight following the deletion, the instances of the event are found again and synchronized to the device, then deleted again.  The end result is correct, however, the user may see duplicate PIM notifications for the second addition and deletion.
