XP / Outlook 2003, PST files

I wondered if there is any shareware out there that will allow me to read the email files from Outlook outside the Microsoft environment? The second part of the question is can you save emails in Outlook to say a travel drive and past them back into Outlook on another machine to read them? Any help would be apprecaited.

 

answer to the second part of the question. you can export the email in pst format choose only the inbox out box ..ect then import them to another machine the same way. i set up 3 of my computers so i have the same email and contacts on three machines this way.
