Office 365 Message Encryption is packaged and sold as part of Windows Azure Rights Management, giving customers a complete solution that includes Information Rights Management (to help safeguard digital information from unauthorized use) and Office 365 Message Encryption (to encrypt and send secure email messages to anyone). With the upgrade, your organization will receive and benefit from both capabilities. For more information, see Active Directory Rights Management Services Overview.
Information Rights Management (IRM): Functionality that helps safeguard digital information from unauthorized use by applying various IRM options to your email messages. IRM improves the security of your SharePoint libraries by setting up appropriate permissions. Files are protected both online and offline, whether they are viewed by using Office Online or downloaded to a local device.
Office 365 Message Encryption: A policy-based service that lets email users to send encrypted email messages to anyone. You can set policy by defining encryption rules and you have the option of customizing encrypted email messages with your brand. Office 365 Message Encryption complements IRM by helping to secure information that is sent to external recipients.
After the upgrade from Exchange Hosted Encryption (EHE) to Office 365 Message Encryption, the licensing section of the Office 365 admin center will show a Windows Azure Rights Management upgrade subscription with a price of $0. This subscription will expire together with your current EHE subscription and you will be offered the ability to use the new Office 365 Message Encryption service as part of Windows Azure Rights Management. The price is set at $0 to prevent you from being charged for the new encryption service while your EHE agreement is still active.
When your EHE subscription expires, your initial Office 365 Message Encryption subscription will also expire. At that time you will have to purchase a Windows Azure Rights Management subscription to continue to use the new Office 365 Message Encryption service. You can make this purchase through the Microsoft Office 365 portal or through an authorized Microsoft reseller partner.
