Protected messages allow the sender to set specific permissions on a message, such as Do Not Forward or Do Not Print. If you receive a protected email message sent to the work or school account you use with Microsoft 365 in Outlook or Outlook on the web, the message should open like any other message. You'll see a banner at the top of the message that informs you of any restrictions on the message.

If you're using a different email account or email program, you may receive a notification that you've received a protected message and need to take additional action.  

You can read encrypted messaged on your desktop or mobile phone.
