In November of last year, Microsoft unveiled plans to release Office 365 Message Encryption, a new service allowing you to send encrypted emails to anyone outside your company. Today, the service has become generally available.
The message encryption service means that no matter the end destination of your email being sent via Office 365, Microsoft is adding another level of protection against unauthorized access. This would come in useful for sensitive communications, such as a bank sending credit card statements to their customers or a mortgage broker asking clients for financial information.
To start using the service, you have to purchase a subscription for Windows Azure Rights Management, which already includes Office 365 Enterprise E3 and E4. Users who already have an existing subscription to Office 365 E3, Office 365 E4 or Windows Azure Rights Management will begin to see the message encryption service light up.
