This is a very interesting setting. In my environment I have a lot of users with shared folders in their Outlook mailboxes. Their assistants, secretaries, etc. do a lot of deletions for them. When this happens, the delete does not appear in the mail owner's Deleted Items so it never syncs the new message state with the handheld.
Additionally, we can profile email messages from clients into our document management system. When this happens, the .msg file is copied from the mailbox and onto the static document repository volume. The original then undergoes a hard delete. Thus the same problem occurs.
How much more load should I expect by enabling this feature for my 150 users? Any idea?
Think it would fix the two above-mentioned issues wih status tracking to the handheld?
I would love to put this issue to rest.
