Under "file", there is a tab called data file management, under
data files, all your email regardless archived or not are stored in
that personal folder under a file called outlook.pst.
To access that file, you have to make sure outlook is not
running, go to that folder, copy it and put it into your desired
folder of your desired computer. To access the emails, your other
computer needs outlook, and under the same options above, select to
add that database. Its tedious, and sometimes you might screw
up.
