When I use this Windows 8.1 machine and log in using any of my live.com accounts all attempts to send mail are sent to the Drafts folder. When I go into the Drafts folder I observe all mail continues to display text for a subject but all body text and who the mail was being sent to has been stripped out of the message.

I am able to send and receive using the same live.com accounts when logged in from a Windows 7 machine.
