Grouping with Outlook 2003; Conversation ordering, dates

[moogphp]

We're (just now) moving to Outlook 2003 at my business and thus I can
no longer use Thunderbird that I've been using for quite a while.

Outlook's grouping features seem convenient for the most part, but I
can't seem to duplicate the threaded message behavior that Thunderbird
has.

I can group Outlook messages by Conversation, but only in
ascending/decending order, and unfortunately this is in alphabetical
order.

I want to keep my messages in conversation grouping, but want the most
recently updated conversation at the top of my list. The way I have it
figured out so far, if a new message comes in that has the subject of
"Zebras" it will always be at the bottom of the list even it is newer
than the "Apples" conversation that was last updated 2 weeks ago.

I want message grouped by conversation, but ordered in descending order
by date of last message within the conversation.



Without this sort of ability, the conversation grouping seems to have a
very limited benefit.

If anyone has any thoughts on how to achieve the behavior I'm trying to
figure out, please post - it is greatly appreciated.

Thanks!
