How to encrypt emails using the Outlook client app
To encrypt an email using Outlook it MUST be on the actual Microsoft client app , not the web app nor the native mobile app. Although both the sender and receiver can be using an email that is not specific to Microsoft, i.e. @gmail.com or @yahoo.com will work, to view and send the message the Outlook client app on your computer or mobile device must be used. If the receiver attempts to open the encrypted message via any other email client they will get the following message:
"This message is protected with Microsoft Information Protection. You can open it using Microsoft Outlook, which is available for iOS, Android, Windows, and Mac OS. Get Outlook for your device here: https://aka.ms/protectedmessage.
Microsoft Information Protection allows you to ensure your emails can't be copied or forwarded without your permission. Learn more at https://microsoft.com/rms."
An example is shown below:
For instructions on how to encrypt emails using the Outlook client app, follow the steps below:
- Open the Outlook Client App
- In the upper right hand corner click "New Email" and create a new email and fill out the message body and/or add attachments like normal
- In the tabs above click "Option" then select "Encryption-Only".(Note: if you don't see the option to encrypt click "Connect to RMS to retrieve templates" and from there re-click "Option", "Encrypt", then "Encryption-Only") If you select "Encryption-Only", the message will be encrypted and will be unable to copy, if you select "Do Not Forward" the message will have all the features of "Encryption-Only" with the addition security measure of being non-forwardable to other recipients.
- After your message is filled out. Press SEND and your message is successfully encrypted. (Note: Once again, know that if you encrypt your email the encrypted email will only show within the Outlook client application. For example, if recipient has a Gmail account then they would have to sign onto their XXX@gmail.com account within Outlook Client , then the encrypted message will be accessible.)
