I've read in this forum there is a format change between Outlook 2002 and
Outlook 2007.  I also uderstand that you can configure Outlook 2007 to use
the Outlook 2002 format.

My main system runs Outlook 2002.  When I travel, I move several pst files
to my laptop adn then move them back when I return.  The new laptop will have
Outlook 2007.  Can I configure Outlook 2007 such that it will always see and
write the 2002 format, or will I have to manipulate the laptop before moving
back to the desktop.

Also, what about my contacts?  Any special things I should know there about
moving them?
