Re: microsoft outlook 2007
Even when you uninstall MS Office, it should retain the .pst files on the drive which is really the only thing you need for the email. However, backing up on the external is always a safer idea.
I'm not sure about installing over Access and Publisher 03, it might recognize those products as the MS office suite and it might not as they're individual products and not the entire package. They may need to purchase another license for Office 07 and not just the upgrade version.
However, they installed it previously so it might just work.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
