Java mail outlook appointment issue

[Pedro Pinto]

Hi there to everyone!

I've been reseaching this topic. So far, the best efford for the
operation is:

Can send an e-mail with an outlook meeting request,
User receives e-mail with an attachment file, meeting.ics,
User can open and accept meeting and organizer receives read report
and acceptance,
User and Organizer cannot see the attendees of the meeting.

The issue, has described, is that the invitation is sent well but when
openning with Microsoft Outlook only the meeting organizer appears!
Does anyone knows how to solve this issue?

Thanks in advance.

Bellow goes the code.

public class Mail {

/** Creates a new instance of Mail */
public Mail() {
}


public static void main(String[] args){

try{


MimetypesFileTypeMap mimetypes =
(MimetypesFileTypeMap)MimetypesFileTypeMap.getDefaultFileTypeMap();
mimetypes.addMimeTypes("text/calendar ics ICS");

MailcapCommandMap mailcap =
(MailcapCommandMap)MailcapCommandMap.getDefaultCommandMap();
mailcap.addMailcap("text/calendar;; x-java-content-
handler=com.sun.mail.handlers.text_plain");

//Calendar calendar = builder.build(fin);

String host = "xxx"; //Outbound mail address
String from = "(e-mail address removed)";
String to = "(e-mail address removed)";

// Get system properties

// Setup mail server
props.put("mail.smtp.host", host);

// Get session

// Define message
