Microsoft is currently testing support for S/MIME encryption in Outlook for iOS.

S/MIME allows users to encrypt emails and digitally sign them. The feature is a widely accepted protocol for sending digitally signed and encrypted messages.

The feature is currently in Testflight and will be coming to Android soon.

Outlook for iOS can be found in the App Store here.
