Outlook 2003(old computer) to Windows Live Mail( new computer)

Santa was kind and brought me a new ,Win 7, computer. I'm in the process of transferring all my information to the new machine.File transfer Wizard has brought all the normal stuff over,and the .pst outlook back-up file. I've manged to move my contacts over using a memory stick(as a CSV file) but same trick won't work for saved e-mail. I also need to bring my Calender over.
All the info is in the  .pst file, but I gather that only Outlook can open this ; does anybody know how I can transfer the Calender and e-mails?
Thanks in hopeful anticipation,
Arthur
