Slow synchronization and disappearing calendar items using Exchange 2007 and iOS 4.3.3

We have seen different situations of a meeting coming from an Outlook client to a user with an iPhone and iPad appearing as accepted (without accepting). After a while 1-5 minutes the item changes on the iPhone and iPad into an invitation with a popup and accept possibility. Users also claim items disappearing after accepting them. Has anyone seen similar problems?

Not sure if your issue is related to this, but Microsoft says in a couple of their documents that both the principle and the delegate must accept all meeting requests, for a specific meeting even if the item has already been accepted by one or the other. If one accepts, and the other deletes it from their inbox, the meeting will come off the calendar. We found this was one thing that would make accepted meetings vanish. One way to fix this is to ensure that only the principle or the delegate or notified of the meeting, not both. This becomes even more of a challenge when you have multiple instances of the Outlook inbox....iPhone, iPad, Outlook and delegate etc....all must be accepted.
