Encrypted Email in Office365

Office365 allows you to send an encrypted email. Encrypted emails are secured in transit and cannot be read by anyone else other than your intended recipient. You may want to encrypt yout email in the following cases:

  • When sending a confidential or Personally Identifiable information
  • When required by a policy (HIPAA, FERPA, etc)
  • You want to ensure the email is encrypted in transit and is only read by your intended recipient
  • You want to ensure the email cannot be forwarded to anyone else


You can send an encrypted email to other CBC recipients (employees or students) or external recipients. CBC recipients or external recipients who are also on Office365 are able to seamlessly open encrypted emails without any additional steps. Recipients outside Office365 (e.g., Gmail, Yahoo, or other organizations not using Office365) will have to verify their email first before being able to decrypt the email.
