Are you up for a second experiment?
I'd like to know what happens when you have a completely empty Sent
Items folder. Possibly one of the messages in the Sent Items folder gets
some corruption and is stopping the sync process somehow.
Can you follow the steps again to backup your Sent Items folder and
clear the cache? This time, don't return any messages to the Sent Items
folder. Wait for the messages to sync from Exchange.
Now, create a new mail folder and call it something like "Sent Items
(Old)". Move all your Sent Items messages to that folder so that your
Sent Items folder is now empty.
Continue using Entourage normally for a while, allowing your newly sent
messages to begin populating your Sent Items folder.
Try comparing this folder with what you see either in Outlook or OWA on
a daily basis. As soon as you see the problem occur again, note the last
message synced and the next message that didn't get synced.
Anything unusual about that message? Did Entourage generate the message
or possibly Outlook or a mobile device?
By the way, I encourage folks to connect to their backend server
whenever possible. Can you tell me how you're connecting? I have details
here in this blog post:
