Secure email is a must in Windows 10.

A decade ago, Microsoft included S/MIME support in Outlook Express and Outlook. Today it's built into many email apps, but difficult for consumers to use outside of the consumer space. The Mail preview app for Windows 10 doesn't even indicate whether or not an email has been properly digitally signed or not - let alone supporting encryption.

Considering the fact that the US Government is spying on Microsoft customers, it'd be nice if MS helped consumers to protect their information against such intrusion - for example, by making it easier to prevent tampering by allowing users to digitally sign emails and increasing security by making it easy for users to encrypt messages as well.

I remember a day when browsers didn't even support SSL encryption - but, in order to facilitate online commerce, technologists made so much noise that even laypeople knew it was unsafe to use a browser without security features - and now all browsers support SSL encryption.

Unfortunately with web-based email and other services, people confuse this padlock icon with end-to-end encryption that will protect them against invasions of privacy or warrantless searches.

The Insider program has over 3.7 million members around the world... it's a shame that there are only about ten posts complaining about lack of email security features in the Windows 10 feedback app.

To protect it's customers, MS should commit to helping customers to encrypt their email across devices - and to have this capability on all devices.

I'd like to ask you all to provide feedback on the mail app and ask for encrypted email support today... before it's too late.
