How to set security level in outlook

Question

Hi I am developing a functionality that sends emails to outlook accounts under company domain. I am using javax.mail:

        MimeMessage msg = new MimeMessage(session);
        msg.setRecipients("to", InternetAddress.parse(to));
        msg.setFrom(new InternetAddress(from));
        msg.setSubject(subject);
        msg.setSentDate(new Date());
        msg.setContent(content);
        Transport.send(msg);

I want my messages to be titled in Outlook like this:

Is it possible to do? Is it possible to indicate C4 level of security somehow from java code?

Were you able to find the solution, we are also stuck here ? — Ankit Wasankar

Looks like you are interested in setting up MIP sensitivity label on the email. See C# - Add MIP specific headers to MailMessage for more information.

I'd recommend exploring the Outlook internals with labels set using MFCMAPI or OutlookSpy, so you could find what exactly should be set up for the message on the sender side.

Hi, please pay attention to tags, I did not mention C#, actually I think C# is the worst programming language in the world, it is slow and good for nothing :)

Ha-ha... Well, the syntax looks like C#, that is why I mentioned it in my response. I'd suggest exploring message internals (especially headers) to understand what is expected from your Java code.
