I've just recently installed Office 2K7 on a friend's machine, and
want to set up two user accounts on the same machine to share
contacts and emails.

Different Windows users? See this:

Where does Outlook 2007 store this information, or is there any easy
procedure to get two user accounts pointing at the same mail store?

Outlook 2007 keeps the data in the same place as prior versions of Outlook,
but its location depends on the version of Windows. Windows XP, for
example, uses a different location than Vista.
