On the subject line, type [Encrypt]: insert subject for e-mail. Type the body of the e-mail and the external recipient's e-mail address. When the external recipient receives your e-mail, it will provide them with instructions on how to open the encrypted message.
How do you encrypt an email in the subject line?

How do you send a secure email subject line?
If you are sending a message using a desktop client such as Outlook or Apple Mail, verify that your client is configured correctly. Put Secure: anywhere in the subject line of the message and then continue typing your subject line. Compose your message and send it as you would normally.
Does put secure in subject line encrypt email?
Writing the word Secure in the subject line of the email can be a method to encrypt a specific email. The recipient of the email enters a passcode provided separately in order to open the email. Using a business solution can simplify the process for receiving encrypted emails.
Are Outlook emails encrypted?
Currently, Outlook.com uses opportunistic Transport Layer Security (TLS) to encrypt the connection with a recipient's email provider. However, with TLS, the message might not stay encrypted after the message reaches the recipient's email provider. In other words, TLS encrypts the connection, not the message.
