发送后如何保存MailItem

Question

i'am创建mailItem：

    Application outlook = new Application();
    _mailItem = outlook.CreateItem(OIItemType.olMailItem);                
    Inspector inspector = _mailItem .GetInspector;
    inspector.Activate();     

设置收件人，身体等...订阅发送事件：

    ((ItemEvents_10_Event)_mailItem).Send += MailItemSendHandler;
    void MailItemSendHandler(ref bool isSended) {
        _mailItem.SaveAs(filePath);
    }

用户发送电子邮件时，我将其保存。但是我的电子邮件保存在 Compose 模式下。如果我要在Outlook中打开它，我可以更改所有信息并可以重新发送。

如果我订阅了MailItem Inspector关闭事件：

 ((InsPectorsEvents_10_Event)inspector).Close += CloseEventHandler;

和在CloseEventHandler中保存MailItem，我有一个错误：

"项目已移动或删除"。

将其发送并在"发送" Outlook文件夹中发送并移动后，我该如何保存邮件？（保存在读取模式中）

编辑

我使用items.additem事件保存我的已发送_mailitem。获取文件夹：

_sentFolderItems = _mailItem.SaveSentMessageFolder;

在_addeventhandler中订阅一些逻辑：

_sentFolderItems.Items.ItemAdd += _addEventHandler;

好：

1. Outlook主窗口正在运行。
2. Outlook过程显示在任务管理器中。
3. I'AM生成MailItem，向用户展示它。用户愿意，请按下发送按钮。
   4。items.itemadd被触发并执行_addeventhandler。
4. Outlook Mail窗口仍在运行，并且在任务管理器中显示Outlook过程。

坏：

Outlook主窗口未运行，任务管理器中没有进程。 我正在生成MailItem，向用户显示它。只有向用户显示的电子邮件发送的窗口。Outlook过程显示在任务管理器中。用户如果愿意进行一些更改，然后按发送按钮。发送邮件，任务管理器确实没有Outlook流程。 items.itemadd未被解雇，_addeventhandler未执行。但是corse send项目位于已发送文件夹中。

在发送项目文件夹上使用Items.ItemAdd事件。
