Install Windows Live Mail 2012. Setup the Hotmail/Outlook.com account.
Once setup it will sync down all messages and folders including
subfolders that are present on the Hotmail/Outlook.com web UI. Do not
interrupt the sync process ( a large volume of message will take time to
sync - i.e. this is walk away and do something else time)
Once complete, use Windows Live Mail's included option to export the
entire account's content (folders, subfolders, messages). Do not choose
the 'Selective option' when exporting/backing up. You will be required
to use a blank folder as the destination for the backup/export. Again -
do not interrupt [walk away time]
Once done the destination folder will have the entire contents in
identical folders as viewed in Windows Live Mail or the
Hotmail/Outlook.com web UI.
- each message in the destination folder/subfolder will be saved as a
single file with the *.eml extension. To view the title or subject of
the messages in Windows Explorer ensure Explorer is configured to show
the column - Title or Subject.
