Open existing PST in write mode

The following example shows you how to open an existing PST file in read/write mode, add folders and items, and save the changes back to the same file. New items are built from a com.independentsoft.msg.Message and wrapped in a com.independentsoft.pst.Item.

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import com.independentsoft.msg.Message;
import com.independentsoft.msg.Recipient;
import com.independentsoft.msg.RecipientType;
import com.independentsoft.pst.Folder;
import com.independentsoft.pst.Item;
import com.independentsoft.pst.PstAccess;
import com.independentsoft.pst.PstFile;

    public static void main(String[] args)
    {
        try
        {
            PstFile file = new PstFile("c:\\testfolder\\Outlook.pst", PstAccess.READ_WRITE);

            try
            {
                Folder startFolder = file.getMailboxRoot();

                startFolder.addFolder(new Folder("Projects"));

                Folder projectsFolder = file.getMailboxRoot().getFolder("Projects");

                Message message1 = new Message();
                message1.setMessageClass("IPM.Note");
                message1.setSubject("Project kickoff");
                message1.setBody("First meeting notes.");

                Recipient recipient1 = new Recipient();
                recipient1.setDisplayName("Jane Doe");
                recipient1.setEmailAddress("jane.doe@example.com");
                recipient1.setRecipientType(RecipientType.TO);
                message1.getRecipients().add(recipient1);

                Message message2 = new Message();
                message2.setMessageClass("IPM.Note");
                message2.setSubject("Project update");
                message2.setBody("Status update for the project.");

                Recipient recipient2 = new Recipient();
                recipient2.setDisplayName("John Smith");
                recipient2.setEmailAddress("john.smith@example.com");
                recipient2.setRecipientType(RecipientType.TO);
                message2.getRecipients().add(recipient2);

                List<Item> items = new ArrayList<Item>();
                items.add(new Item(message1));
                items.add(new Item(message2));

                projectsFolder.addItems(items);

                projectsFolder.addFolder(new Folder("Archive"));

                file.save();
            }
            finally
            {
                if (file != null)
                {
                    file.close();
                }
            }

            System.out.println("Done.");
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}
