Working with Office 365 and Microsoft 365 Email Encryption

Encrypted Office 365 and Microsoft 365 Email support requires that you have the necessary Office 365 and Microsoft 365 or Exchange Online subscription level from Microsoft and a Cloud App Security Advanced license from SonicWall. Verify that your Microsoft subscription type and any Microsoft add-on packages you have purchased include Microsoft encryption services.

Office 365 and Microsoft 365 Email Encryption encrypts email messages regardless of their destination email addresses (Gmail, Yahoo Mail, Outlook.com, etc.) using Right Management templates. Instead of an email message, a link to the email message is sent to the recipient. The encrypted email messages can be viewed after the recipient provides proper authentication.

Cloud App Security Data Leak Protection (DLP) policies for Office 365 and Microsoft 365 Email (Exchange Online) include an automated workflow that allows email messages that violate an enabled Cloud App Security DLP policy to be encrypted before being sent using the existing Office 365 and Microsoft 365 Encryption services.

Cloud App Security integrated with Office 365 and Microsoft 365 Email Encryption by:

• allowing you to create workflow rules when you create DLP email message policies to automatically encrypt Office 365 and Microsoft 365 email messages (refer to Creating Data Leak Protection Policy Rules for more information about creating DLP policies)
• intercepting email messages in Protect (inline) mode and evaluating them against your DLP policy rules
• encrypting email messages that match the DLP policy rules using the “Email is allowed. Encrypted by Microsoft” workflow
