Microsoft: We're Advancing Our Encryption And Transparency Efforts

It would seem that Microsoft is stepping up its webmail security by activating Transport Layer Security encryption for its Outlook and Hotmail services.
First, Outlook.com is now further protected by Transport Layer Security, or TLS, encryption for both outbound and inbound email. This means that when you send an email to someone, your email is encrypted and thus better protected as it travels between Microsoft and other email providers. Of course, this requires their email service provider to also have TLS support.
