Users can send encrypted message to recipients that have an encryption certificate.

Users can digitally sign a message, which provides the recipients with a way to verify the identity of the sender and that the message hasn't been tampered with. To read the messages, recipients must have a digital identification (ID), also known as a certificate. S/MIME enables users to encrypt outgoing messages and attachments so that only intended recipients can read them. Secure/Multipurpose Internet Mail Extensions (S/MIME) provides an added layer of security for email sent to and from an Exchange ActiveSync (EAS) account.
