What upgrade? OL 2007 is the latest version and is a component of certain
Office 2007 versions

If you have lost your Office 2007 cd/dvd you are basically stuffed as I
would guess you dont have proof of purchase either

I just purchased the upgrade for Outlook 2007 for my pc and I want to
install
it. All other windows programs (Office)are complete but I need to
update
Outlook. Can I do that without having the registration number I had in
the
beginning when I installed Office 2007? This was years ago and I no
longer
have the program. Help!
