How do I encrypt an email using Outlook online? Go to the following weblink https://outlook.office.com/ (The above link can also be located on the Intranet page under Tools, labelled "MKUH Office 365") Once you have signed in with your mkuh.nhs.uk email address, click on New Message and select the Encrypt option (if this does not appear at first, please click on the ellipses button and select the Encrypt option as shown below). Depending on the email provider the recipient may be asked to open the email and then sign in using a onetime code or the email may be visible to the recipient but will have a box detailing that it is encrypted. When you click on Encrypt you may notice that the following option appears at the top of the email box: ENCRYPT: This option encrypts the email. The recipient will need to follow the instructions in the email to be able to read it. DO NOT FORWARD: If you choose this option it will Encrypt the email but it will also block the recipients from forwarding the email to anybody else.
