Microsoft is giving regular users the ability to revoke encrypted email messages sent using Office 365 Message Encryption (OME), as part of an effort to prevent data and corporate data theft. Until now, this ability was only available to administrators. OME is based on Microsoft Azure Rights Management (Azure RMS) and combines rights management with encryption . It also allows Office 365 users to send and receive encrypted messages using Outlook.com, Yahoo!, Gmail, and many other services with support for encryption, authorization, and identity policies.
Microsoft has announced that it will be expanding the ability to recall emails to end users, noting that previously, you had to be an administrator to be able to recall a message that had already been sent. This new feature will only be available to users with Office 365 subscriptions with advanced message encryption support, such as Microsoft 365 Enterprise E5, Office 365 E5, Microsoft 365 E5, Office 365 Enterprise E5, and Office 365 Education A5. While Microsoft did not specify what exactly will happen to the recalled encrypted messages, according to the company's official website, when administrators recall such emails, recipients will receive a notification "The message has been recalled by the sender" when trying to access the encrypted messages through the Office 365 Message Encryption portal.
The Microsoft Exchange team plans to roll out this new expansion in Q4 2020, making it available globally. As part of its efforts to stop enterprise, Microsoft also plans to remove the ability to forward Office 365 emails to external recipients by default, starting in Q4 2020. The company is also in the process of adding improved external email forwarding controls, which will allow Office 365 administrators to enable the feature for as many employees in their organization as they want. Microsoft is also working to improve how emails sent through the OME service are identified by mail servers, so that they are less likely to be sent to the trash after being marked as spam.
