Below is the code snippet i am trying 

 Properties props = new Properties();
                Session session = Session.getDefaultInstance(props, null);
                try {
                    MimeMessage mimeMessage = new MimeMessage(session, mailFileInputStream);
                    Object content=mimeMessage.getContent();
                    BodyPart messagePart = null;
                    int count = ((Multipart) content).getCount();
                    //count is always =2
                    messagePart = ((Multipart) content).getBodyPart(0);

I tried with messagePart = ((Multipart)content).getBodyPart(1); as well because count is 2 but not able to get attachement

  • I need more detail. What exactly does "not able to get" mean? What happens? What do you expect to happen? Have you read the JavaMail FAQ? In particular, [this entry about reading attachments](https://javaee.github.io/javamail/FAQ#readattach)? If you're using Office365, why are you reading the message content from a file? – Bill Shannon Nov 06 '17 at 07:02

The message you're dealing with has a more complex structure than you're expecting. See the msgshow.java sample program for an example of how to iterate over all the message parts and extract the "attachments".
