Why send encrypted email?
People sometimes use email to exchange sensitive information, such as financial data, legal contracts, confidential product information, sales reports and projections, or customer and employee information. With Microsoft 365 Message Encryption, encrypted email messages can be sent between people inside and outside of the university. Office 365 Message Encryption works with Outlook.com, Yahoo!, Gmail, and other email services. Email message encryption helps ensure that only intended recipients can view message content.
What is the tradeoff when sending encrypted email?
Encrypted email adds additional security to the message, but may also create additional steps for the recipient to view the message. Encrypted email messages can be read directly in Outlook on the web (OWA), in Outlook for iOS and Android, and Outlook for Windows versions 2019 and Microsoft 365. Other email clients will see a message with a link. That link will take Microsoft 365 users to OWA to read the message. Users with other email accounts will be prompted to obtain a one-time passcode and read the message in a browser window.
