I am using Entourage with exchange on my Mac. I sync between laptop, iPhone and desktop. My sent items were not syncing to my desktop and phone right so I emptied the cache on my "sent" folder on my desktop. I thought that the exchange server had the correct messages but that my desktop was not getting them correctly. I was wrong, turns out my desktop had everything but it hadn't been syncing to the server for a few weeks. My desktop had all the messages and the server did not. So when I emptied the cache all of my sent items on my desktop disappeared and were replaced with the ones on the server. (I know, I should have known better.) Anyway, I use time machine and have lots of backup. Is there a way to locate the file for the exchange messages that I had yesterday and restore them?
