Microsoft discontinued Outlook Express beginning with Windows Vista. It was superseded by Windows Mail in subsequent Windows releases. At that time, all of an Outlook Express user's emails were located in a folder named "Outlook Express." If you still have that folder and can locate it on your Windows computer, you can import the Outlook Express mail into Mozilla's Thunderbird email client.
