Answer 1

Here is a java file that connects to a users exchange account, reads all messages, and writes the attachment to the file system.
import java.io.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class TestNew {
public static void main (String args[]) throws Exception {
// Create empty properties
Properties props = new Properties();
// Get session
Session session = Session.getInstance(props, null);
// Get the store
Store store = session.getStore("imap");
// Connect to store
store.connect(host, username, password);
// Get folder
Folder topFolder = store.getDefaultFolder();
Folder folder = literature.getFolder("newFolder");
folder.open(Folder.READ_WRITE);
Message[] msg = folder.getMessages();
for(int i = 0; i < msg.length; i++){
Address[] from = msg.getFrom();
String subject = msg[i].getSubject();
Object o = msg[i].getContent();
if (o instanceof MimeMultipart) { //attachements available?
MimeMultipart mm = (MimeMultipart) o;
int mmCount = mm.getCount();
for (int m = 0; m < mmCount; m++) { // for each part
Part part = mm.getBodyPart(m);
String disposition = part.getDisposition();
if ((disposition != null) && ((disposition.equals(Part.ATTACHMENT) || disposition.equals(Part.INLINE)))) {
InputStream is = null;
File tempFile = new File("D:\\TEMP\\mailtest\\" + part.getFileName());
FileOutputStream fos = null;
try {
fos = new FileOutputStream(tempFile);
is = part.getInputStream();
int byteCount = 0;
byte[] bytes = new byte[128];
while ( (byteCount = is.read(bytes, 0, bytes.length)) > -1) { //use full read() method for GZIPInputStream to be treated correctly
fos.write(bytes, 0, byteCount);
finally {
try {
if (fos != null)
fos.close();
catch (IOException ioe) {}
try {
if (is != null)
is.close();
catch (IOException ioe) {}
System.out.println("Content: " + o);
System.out.println(from[0].toString());
System.out.println(subject);
