I'm trying to see whats required to get email encryption setup in Outlook. We have a client who is a home health agency and needs to encrypt all emails coming from their Exchange 2003 server containing confidential information in order to meet HIPAA compliance and send emails to companies. We actually did get some pretty strong encryption setup through Barracuda, but this company that the client is sending emails to apparently lacks the mental capacity to log into a web portal and retrieve emails. So now I'm trying to get outlook to encrypt emails so that they don't have to think much more past "click, open email". The thing I'm not understanding is how these digital ID's work, I was reading an article online but it didn't tell me everything that's required for Outlook to encrypt emails. The things I'm wondering are:
Does the recipient also need to purchase a digital ID to encrypt the message? (if the answer to this question is yes then solution isn't viable anyways)
Does each computer thats going to send encrypted emails have to have their seperate digital ID?
Does each recipient have to add the digital ID for each person into their contents to decrypt messages? For example, if ten people are sending encrypted emails from my client to 20 agents on the other side, does each one of the 20 agents have to go in and add all 10 digital ID's
Also does having exchange affect things at all.
The client is running SBS 2003 with Exchange 2003
Any help is greatly appreciated, any other suggestions are welcome, and if I left anything out let me know. Thanks.
