Encrypting an Email

Outlook Client 

Compose a new message and then choose the Options tab at the top, and select Encrypt>Encrypt-Only, then hit Send. This will encrypt the email and any attachments to that email.

Outlook Web Access (OWA)/ New Outlook

Compose a new message and then choose the Options tab at the top, the select Encrypt>Encrypt and hit Send. This will encrypt the email and any attachments to that email.

The recipient (Gmail in this case), receives a message similar to the below. Click ‘Read the message’ and they will be taken to a website. NOTE: THIS ONLY OCCURS FOR EMAILS OUTSIDE OF MICROSOFT 365. OUTLOOK USERS ALREADY AUTHENTICATED TO O365 WILL AUTOMATICALLY BE ABLE TO READ THE MESSAGE.

The website will then ask them to sign in to view the encrypted message. They can sign in with an existing identity based on their email system or receive a one time passcode via email.

The message is then displayed in the portal and the user can reply from there.
