I have sorted emails that I want to save into folders on the Windows Mail App and am wanting to save only the emails in those folders to my HDD or a USB drive. I've read a couple of posts that say to hit Alt+F and select export but nothing comes up when using the app. I think I'm running Windows 8 or 8.1. I'd really like to avoid having to sort through thousands of emails again so any help is greatly appreciated. Thanks.
