I just upgraded to a Windows 8.1 PC. I was able to retain Windows Mail even though Windows 8.1 says you cannot use POP3 email service. For those having the same issue, go to Windows to download and install Windows Essentials. Now that I have done that, I want to migrate my local email folders to my new PC. Does anyone know how to do this? Where I can find the folders where emails are located on my old PC hard drive? Thanks.
