C# 创建新的Outlook应用商店

我正在Outlook中使用C#和Addin express创建pst文件

新的pst文件（“我的收件箱”）应包含收件箱、已发送邮件和发件箱

Outlook.Folders olFolders = olNamespace.Folders;
        foreach (Outlook.MAPIFolder olTmpFolder in (IEnumerable) olFolders)
        {

            if(olTmpFolder.Name == "My Inbox")
            {

                olTmpFolder.Folders.Add("Inbox", Outlook.OlDefaultFolders.olFolderInbox);
                olTmpFolder.Folders.Add("Sent", Outlook.OlDefaultFolders.olFolderSentMail);
                olTmpFolder.Folders.Add("Outbox", Outlook.OlDefaultFolders.olFolderOutbox);

            }

        }

但我只能看到收件箱文件夹

如果有更好的方法，请告诉我

谢谢

试试这个，告诉我它是否有效：

Outlook.Folders olFolders = olNamespace.Folders;
        foreach (Outlook.MAPIFolder olTmpFolder in (IEnumerable) olFolders)
        {
            if(olTmpFolder.Name == "My Inbox")
            {

                olTmpFolder.Folders.Add("Inbox", missing) as Outlook.Folder;
                olTmpFolder.Folders.Add("Sent", missing) as Outlook.Folder
                olTmpFolder.Folders.Add("Outbox", missing) as Outlook.Folder
            }
        }
