This has an option to convert the body to html like the example below:
import java.io.IOException;
import com.auxilii.msgparser.Message;
import com.auxilii.msgparser.MsgParser;
public class ParseMsg {
public static void main(String[] args) throws UnsupportedOperationException, IOException {
MsgParser msgp = new MsgParser();
Message msg = msgp.parseMsg("mail.msg");
System.out.println(msg.getConvertedBodyHTML());
}
}
Did some tests with a couple of mails. The outcome is quite good for simple mails. More complex mails with images and tables etc. do not return correctly as html. But it depends on your needs, so this might be a valid option. It uses POI under the hood.
