How do I open a protected message?

Protected messages are a secure form of communication provided by Office 365. When sensitive information needs to be communicated, you may receive a notification email with a link to “Read the message”. If you receive a protected email message sent to your Office 365 account in Outlook 2016 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.

  4. Enter the code in your browser, then select Continue to read your message.
