I have a custom arrangement set up for that very purpose.
Group items by: Subject
Sort groups by: Sent Newest on Top
Sort items within groups by: Sent Oldest on Top
Default display for groups: Expanded
I suggest you give that a try to start. With the newsgroup open, go to View
Arrange By > Edit Custom Arrangements. Click the "New" button, and create
the one above. Then, click OK, and close the Custom Arrangements window.
Go to View > Arrange By > <whatever you named the Custom Arrangement>. Now,
the messages will be grouped by subject. The groups with the most recent
entries appear at the top, and the messages within each group are sorted
chronologically with the oldest messages at the top.
That should get you started. You are free to change the Custom Arrangement
to work best for your needs. Just go to View > Arrange By > Edit Custom
Arrangements, and double-click the arrangement. You can experiment with
different settings to achieve the view you want.
Unfortunately, because Entourage does not thread by reference, any messages
with slightly modified subjects or non-standard prefixes (like Re : or AW

will not be grouped properly. Also, threads can't be viewed in the format
