Need to send a an Outlook attachment with an Email

Question

Hello everyone ,
I have a requirement in which I need to send an attachment in a mail as an Outlook attachment. I have used the following code and i am wondering what I would need to change so that the Outlook attachment works fine -
public static void sendMessageWithAttachments(EmailPoller emailPoller,String body,String toAddresses,String ccAddresses,String subject, BlobDomain associatedEmail)
throws MessagingException,Exception {
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
// Fill in header of the email
message.setSubject(subject);
message.setContent(message, "text/plain");
if ((toAddresses != null) && (toAddresses.trim().length() > 0)) {
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(toAddresses));
if ((ccAddresses != null) && (ccAddresses.trim().length() > 0)) {
message.addRecipient(Message.RecipientType.CC,
new InternetAddress(ccAddresses));
// Create a multi-part to combine the Mime Body parts
Multipart multipart = new MimeMultipart();
// Create your new message part to set text inside email & add it to teh multipart
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(body);
multipart.addBodyPart(messageBodyPart);
// Create and fill MimeBodyPart for the attached content& add to multi part
messageBodyPart = new MimeBodyPart();
DataSource source = new ByteArrayDataSource(associatedEmail.toByteArray(),"text/plain");
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName("associatedEmail.txt");
multipart.addBodyPart(messageBodyPart);
// Associate the multi-part with message content
message.setContent(multipart,"text/html");
emailPoller.forwardMessage(message);//send email with attachments
}What I tried was to set the MIME-type for the datasource @
DataSource source = new ByteArrayDataSource(associatedEmail.toByteArray(),"text/plain");to application/vnd.ms-outlook but it does create an Outlook message as an atatchment but refuses to open it and shows an Error.
Anyone who know how to make it work please ?

Thanks a lot ... worked perfectly fine.
DataSource source = new ByteArrayDataSource(<BlobHavingEmailDetails>.toByteArray(),"message/rfc822");
messageBodyPart.setDataHandler(new DataHandler(source));
//etc ... attach MimeBodyPart to MimeMultiPart to send the message with Body & attachment.Yes I wanted to attach another complete message to another one.
