Hi, thank you.
My problem is I have a large Outlook .pst file given to me and I want to import it. I don't want to touch Windows mail because I'm scared of what could happen. I thought if I could also install O.E., I could import the .pst file to O.E. and if O.E. croaks, well that's life. At least Windows mail would stay okay. I brought down Mozilla's thunderbird, but it imports nothing that I could find.
