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.

C# example

using System;
using System.Collections.Generic;
using Independentsoft.Pst;

namespace Sample
{
    class Program
    {
        static void Main(string[] args)
        {
            PstFile file = new PstFile("c:\\testfolder\\Outlook.pst", PstAccess.ReadWrite);

            using (file)
            {
                Folder startFolder = file.MailboxRoot;

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

                Folder projectsFolder = file.MailboxRoot.GetFolder("Projects");

                Item item1 = new Item("IPM.Note");
                item1.Subject = "Project kickoff";
                item1.Body = "First meeting notes.";

                Recipient recipient1 = new Recipient();
                recipient1.DisplayName = "Jane Doe";
                recipient1.EmailAddress = "jane.doe@example.com";
                recipient1.RecipientType = RecipientType.To;
                item1.Recipients.Add(recipient1);

                Item item2 = new Item("IPM.Note");
                item2.Subject = "Project update";
                item2.Body = "Status update for the project.";

                Recipient recipient2 = new Recipient();
                recipient2.DisplayName = "John Smith";
                recipient2.EmailAddress = "john.smith@example.com";
                recipient2.RecipientType = RecipientType.To;
                item2.Recipients.Add(recipient2);

                IList<Item> items = new List<Item>();
                items.Add(item1);
                items.Add(item2);

                projectsFolder.AddItems(items);

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

                file.Save();
            }

            Console.WriteLine("Done.");
            Console.WriteLine("Press ENTER to exit.");
            Console.Read();
        }
    }
}
