Microsoft has been rolling out an update to Office 365 tenants that adds Windows Azure Rights Management and Office 365 Message Encryption. The initial deployment of these technologies were targeted towards customers in the enterprise cloud; referred to as “E” tenants. Customers in our Government Community Cloud (GCC) environment have not had access to these capabilities until recently.
A co-worker has written up a great blog post that shows how to setup Office 365 Message Encryption in a GCC tenant. Check it out here.
