How to Send a Secure Email via Office 365

When you need to protect the privacy of an email message, encrypt it. Encrypting an email message in Office 365 Outlook means it's converted from readable plain text into scrambled cipher text. Only the recipient who has the private key that matches the public key used to encrypt the message can decipher the message for reading.
