I used to have an application years ago that would allow messenger to
write a new Journal each time which included all the message and the
time the chat took. Many years ago they stopped selling it as I think
it did not work with Outlook XP or 2003, I now have Outlook 2007.

I keep a lot of stuff in Outlook 2007 and would love to be able to do
this again so I can easily search chats.
