People that use Outlook also tend to have more... valuable conversations in their inbox and demand more in terms of security and privacy from their mail providers. I hope that as part of courting this group of users to outlook.com, Microsoft has invested in things like S/MIME, PGP, 2FA, and other security enhancements. I haven't signed up, but can someone who has give an outline of what security features they are advertising?
