Original title: WinXP Outlook conversion to Win10 Windows Live Mail

How do I or sadly can I EXPORT my Contacts (600) and Messages (2000) from WinXP Outlook 2003 and IMPORT into them into my new Win10 Windows Live Mail 2012. It seems Windows Live does not recognize .cvs and .pst formatted packets as typical for so many years. I did under much stress use the comma-delimited Excel option for the contacts. But there is nothing (except for 3 useless formats choices) for messages. Please help me.
