You could pretty easily use Microsoft IRM to do that if you wanted to have your Exchange server(s) on-premise. A number of other solutions as well. However, the state of CA uses Office 365, including their HIPAA regulated content. It's encrypted "at rest" which is the requirement for most all types of data. Hit me offline if you want to chat more. I did the email design for John Muir, Kaiser, Blue Shield Hawaii and have written a few books on the topic. Happy to help out
