O365 delivers multiple encryption options to help us meet our needs for email security. This article describes how to encrypt email in Office 365.
IMPORTANT: In order to make use of the features in this article, your Outlook client must be at least version 16.0.11126.20188, which is the December 2018 build of the O365 Office client. To check which version you're running you can:
If you are using Windows 10 and your Outlook doesn't match the images above, you're likely using an older, unsupported version of Outlook, such as Outlook 2003. You can often find the Outlook product version by selecting Help > About.
If your version is not at least 16.0.11126.20188, contact your departmental IT staff for assistance in upgrading, or download the latest version from http://officedownload.uic.edu. You can also use the web client to access O365 regardless of the version of Outlook you have installed locally and take advantage of the latest technology by going to http://outlook.uic.edu. You will likely see a certificate warning if you follow the previously noted link. It is safe to proceed.
Microsoft released a feature update for Outlook In version 1812 (Build 1126.20188) that puts all your encryption options in one place. The encryption feature lets you share your confidential and personal information while ensuring that your email message stays encrypted and doesn’t leave Office 365
Outlook for O365 365 client (Windows) -- In a New Email message, choose Options, select Encrypt and pick the encryption that has the restrictions you want to enforce, such as Encrypt-Only or Do Not Forward.
Outlook for Mac -- In anew email message, choose Options, select Encrypt and pick the encryption that has the restrictions you want to enforce.
Outlook on the Web (Windows) -- in a New Message, select Encrypt, click on Change permissions to pick the encryption restriction you want to enforce.
When the encrypted message arrives in the external recipient's mailbox they will need to click on the "Read the message" button where it will redirect them to the secure portal.
The secure portal will give the recipient two options to view the encrypted message.
Once the user has authenticated with either their social ID (email provider) or a one-time passcode, they will have the ability to view the encrypted message and reply within the secure portal.
If the sender selected Do Not Forward when sending the encrypted message, the Forward and Print options will be grayed out.
Yes, to view the content they will always be redirected to the secure portal no matter what option they select.
Yes. In order to allow the new recipient of the forwarded message to successfully view the secure message, the forwarder needs to ensure the forward action is done inside of the secure portal where they can see the encrypted message. The forwarder will get a notification when performing this action.
*If the forwarder does not forward the message via the secure portal and decides to forward the encrypted notification, the forwarded recipient will not be able to view the encrypted message.
Office for Mac 2019 can be licensed in two ways, either with a perpetual/volume license, or by you signing into your UIC Office365 account when you first launch an Office app (though this is separate from signing into your Exchange account when you first launch Outlook). Microsoft separates some product features away from the volume license, among which is e-mail encryption.
Only University owned devices should be using the perpetual license.
