Outlook my email and contacts files

I have installed a new hard drive and re-installed the
operating system. Next I copied specific files from a
backup onto the new hard drive. The PST files that I had
previously setup for 3 different email accounts were
restored in two places: 1.) Documents &
Settings\John\Microsoft\Outlook\Personal, Business,
General folders. 2.) Documents & Settings\Local
Settings\Application Data\Microsoft\Outlook\several email
storage folders. So far, I have not been able to get
Outlook to recognize any of my folders except the
original defaults.

Can you suggest a method for adding those other existing
folders to my email and contacts lists?
