Data Protection: Sending Encrypted Email

Office 365's Office Message Encryption (OME) provides you the ability to customize the level of protection for any specific email you choose to encrypt. You can choose to just encrypt the email, which ensures it is received by your intended recipient exclusively or to limit their ability to forward the email to others. For messages that require the greatest amount of security, you can choose to allow the email to only be viewed by or forwarded to other Villanova Connect users, or even limit the Villanova recipient to view the email and be unable to copy, print, forward or otherwise interact with the message. These different options will be described in some detail later on.

You can utilize these functions by clicking on the “Protect” button at the top of your email, which will appear next to the “Send” and “Attach” buttons in the Outlook Web App.

In the Outlook 2019 application, which can be installed locally on your computer for more robust email management, you can find the option with the “Encrypt” button when you select “Options.”

In the Outlook Web App, once you click “Protect” you will notice a banner on the top of your email, which says “Do Not Forward: Recipients can read this message, but they can’t forward, print, or copy content.” It will also include options to change the permission level or remove the protection altogether.

From Outlook 2019, once you click “Encrypt” you will see a message stating “Encrypt Only – This message is encrypted.” You can change the permission level by clicking the small arrow to the right of the “Encrypt” button.

 

If you select the option to change the permission level, you will be presented with four different options.

 

Here is what they are and how they function:

Encrypt

If you choose “Encrypt,” the contents of the message will be encrypted. At a very basic level, you can imagine this as your message being converted into a secret code, with only authorized users (your intended message recipient) having the key to decrypt that encoded text back into your original message.

When you choose “Encrypt,” once the recipient gets the message they are free to do what they want with it. They can copy text from the message, print it, save it to their computer, reply to it or forward it to other users. Encryption adds a layer of security that ensures your intended recipient is the only one who can receive your message – but it does not control what they can do with it once they have.

Do Not Forward

If you want a little bit more control over the message you are sending, you can choose the “Do Not Forward” option. This option encrypts the message as described above, but also prevents the user from copying, printing or forwarding the message contents.
