ok this is what i remember about outlook (2000 and prior)...
you can look for it's data files manually and back those files up and restore them to the same path, or....
open outlook and export. during the export process, u will have the option to select what u want to keep (ie - calendar, emails, addressbook, etc).
i don't work with outlook a lot, but i know i have done so in the past. i dont know how accurate my recollections are, so u might want to wait for someone else to confirm or dismiss my info.
