Outlook on the web

  1. Go to the top of the message and select more options extended menu > Message options.

  2. Select or deselect Encrypt this message (S/MIME).

If you encrypt an outgoing message and Outlook on the web can’t verify that all recipients can decrypt the message, you’ll see a notice warning you which recipients might not be able to read the encrypted message. You can then send the message anyway, remove those recipients, or retry to check again.

Outlook on the web requires a Windows desktop device to support S/MIME. S/MIME isn't available in Outlook on the web on Mac, iOS, Android, or other non-Windows devices.

Internet Explorer 11 or one of the three most recent versions of Edge or Chrome is required to send and receive encrypted messages, digitally sign messages that you send, and to verify digital signatures on messages that you receive.
