How to Retrieve the Members of a Private Distribution List

The following piece of code demonstrates how to retrieve the members of Private Distribution List stored in a user's Contacts folder. For more information about any CDO object or method used below, please refer to the Microsoft CDO reference. Before running this code, please ensure that you have first configured CDO.

import com.intrinsyc.cdo.*;
import com.linar.jintegra.Cleaner;

public class RetrievePrivateDLMembers {

    public static void main(String[] args) {

        //TODO: Change the following parameters based on your setup and configuration
        // the logon parameters of the service account you used to configure CDO
        String domain           = "domain";
        String username         = "username";
        String password         = "password";

        // the DNS name or IP address of the machine where you installed CDO
        String CDOmachine       = "";

        // the DNS name or IP address of the Exchange Server
        String exchangeServer   = "";

        // the mailbox you wish to access (NOTE: this is the same as the user's login name
        // e.g., if the username is jsmith, mailbox would also be jsmith )
        String mailbox          = "mailbox";
	// field and propset ids
	String CdoPropSetID3 = "0420060000000000C000000000000046";
	String CdoContact_PrivateDLMemberIDs = "0x8054";

			AddressEntry addr = new AddressEntryProxy(session.getAddressEntry(ID));
			System.out.println(" ...... " + addr.getName().toString());

            // log off from the session

        } catch (Exception ex) {
        } finally {
            // clean up and release all references
