Office 365 Message Encryption is an easy-to-use service that lets email users send encrypted messages to people inside or outside their organization. Designated recipients can easily view their encrypted messages and return encrypted replies. Regardless of the destination email service—whether it’s Outlook.com, Yahoo, Gmail, or another service—email users can send confidential business communications with an added level of protection against unauthorized access.
Exchange Online and Exchange Online Protection (EOP) administrators set up Office 365 Message Encryption by defining encryption rules. As an administrator, you can also customize encrypted messages with your own text and logo, presenting a company brand that’s familiar to message recipients.
Office 365 Message Encryption is an online service that’s built on Microsoft Azure Rights Management. With Azure Rights Management set up for an organization, administrators can enable message encryption by defining transport rules that determine the conditions for encryption. A rule can require the encryption of all messages addressed to a specific recipient, for example.
When an Exchange Online user sends an email message that matches an encryption rule, the message is sent out with an HTML attachment. A recipient opens the HTML attachment in the email message, recognizes a familiar brand if that’s present, and follows the embedded instructions to sign in, open, and read the encrypted message on the Office 365 Message Encryption portal. The sign-in process helps ensure that only intended recipients can view encrypted messages.
The following diagram summarizes the passage of an email message through the encryption process.
