Reterieve/download email attachments from MS Exchange Server

Question

Hi,
Is there a way to check for new emails and download any attachements from MS Exchange Server. I want to check for any new emails from some specific contact, then check if there are any attachments, if any attachments i.e. .txt,.doc,.zip etc. I then want to download and save them on a filesystem. Can someone please help me out how to proceed and small example will help. Thanks

javax.mail.AuthenticationFailedException: There is no such mailbox on this server
     at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:104)
     at javax.mail.Service.connect(Service.java:256)
     at javax.mail.Service.connect(Service.java:135)
     at javax.mail.Service.connect(Service.java:87)
     at mypackage.Fetch.main(Fetch.java:26)Here is the sample I am using:
package mypackage17;

    String host = "mail.some.com";
    // Get system properties
    Properties props = System.getProperties();
    props.put("mail.pop3.host", host);
    // Setup authentication, get session
    Authenticator auth = new PopupAuthenticator();
    Session session = Session.getDefaultInstance(props, auth);
    // Get the store
    Store store = session.getStore("pop3");
    store.connect();
    // Get folder
    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_WRITE);
    // Get directory
    Message message[] = folder.getMessages();
    for (int i=0, n=message.length; i<n; i++)
       System.out.println(i + ": " + message.getFrom()[0] + "\t" + message[i].getSubject());
try

/*On Mail system when you recive a mail with attachment the format of the message is a multipart/mixed*/
if (message[i].isMimeType("multipart/mixed"))
Multipart mp = (Multipart) o;
int cnt = mp.getCount();
for (int j = 0; j < cnt; j++)
Part part = mp.getBodyPart(j);
System.out.println("********** " + part.getFileName());
String disposition = part.getDisposition();
if ((disposition != null) && ((disposition.equals(Part.ATTACHMENT) || disposition.equals(Part.INLINE))))

while ((byteCount = is.read(bytes, 0, bytes.length)) > -1)

fos.write(bytes, 0, byteCount);
finally
try

package mypackage;
import javax.mail.*;

import java.util.*;
public class PopupAuthenticator
    extends Authenticator {
  public PasswordAuthentication
      getPasswordAuthentication() {
    String username, password;
    String result = JOptionPane.showInputDialog(

    StringTokenizer st =
      new StringTokenizer(result, ",");
    username = st.nextToken();

}Can someone help what is wrong that I am unable to connect. Thanks
