Export your emails according to these steps
How to Export Copy of Mailbox from Outlook.com
(extra step is required since this was written - when you go into the settings wheel/cog, you need to click View all settings (at the bottom of the settings window) to get the General > Privacy and Data option)
(Note the Export process is long and painful. The note from Microsoft says " ... up to 4 days to complete"!!!!
Assuming it's downloaded (exported) as a .pst file, download and install eMClient (freeware), import the .pst file and then export the emails as individual .eml files.
Alternatively, you could just setup Thunderbird or eMClient with your outlook.com account (IMAP settings for inwards mail), emails will be populated and you can export as .eml files.
