If your message contains highly sensitive information meant for the recipient’s eyes only, you can encrypt it. When you encrypt a message, Outlook scrambles the text it contains; only recipients with the necessary “keys” can decipher the message.

To share the necessary keys with the recipient, you must exchange certificates. (A certificate is a digital ID.)
