How to send, view and reply to encrypted email in Office 365



Outlook on the Web


Office 365 provides encryption features that are easy to use.  To send an email using encryption, compose the email to an external recipient and include one of the following options in the subject line:

  • Encrypt
  • Secure Message
  • Secure

The recipient will receive notification that an encrypted email message is available and can either sign into their Microsoft Account or use a one-time passcode to view the message.  Using a one time passcode will be the easiest option if they do not have a Microsoft / Office 365 account.

On the top ribbon, click the button that says 'Protect'

Click 'Change Permissions' and change the drop down menu to 'Encrypt'
