Outlook calendar meetings not updating
Outlook was designed to send updates when you change the location or time of the meetings because the attendees need to know when and where the meeting is.
You also can't avoid sending an update when you add a attendee, for the very same reason.
If you are changing the time to add travel or preparation time, I highly recommend creating an appointment for the extra time instead. However, there is a way to trick Outlook into thinking the update was sent: set Outlook offline before sending the update, then open the Outbox and delete the update before going back online.
This is not a perfect solution and I know of at least one issue: if someone accepts or declines the meeting after you delete the update, meeting tracking wont be updated. This method will work for all new meetings or to delete meetings when you don't want to send the cancellation notice.

If you've noticed missing calendar appointments (e.g., lost meetings, delegate issues), or meeting updates from someone other than the original organizer, you're not alone.

Exchange itself is usually not the root of the problem, the mail clients (Active Sync, i OS devices, Blackberries, i Cal) and their connectivity protocol tend to be the culprits. For instance, if someone accepts a meeting at 9am on an i Phone and a delegate declines it at am on a PC, but the i Phone is out of signal range and doesn't sync the meeting until say am., what happens to the meeting?
We had a new executive start and therefore added the executive assistant as a delegate to his calendar.
