It looks like Entourage 2004 has very, very poor Exchange support.
First, it attempts to synchronize all of the folders underneath Inbox and
there appears to be no way to select which folders are synchronized and
which are not. For anyone who has tens of thousands of emails filed in
subfolders of Inbox, this is a real problem. I tried to categorize certain
folders but it looks like limiting which items are synchronized by category
only works with Calendar and Contacts. I also tried to opt to have just
headers downloaded but this doesn't seem to work at all.
Second, Tasks and Notes are not synchronized at all. Why Microsoft doesn't
implement synchronization of these two folders I just don't know.
It just seems ridiculous that Microsoft would ship a product with such poor
support for another one of its products.
