C# 如何在 Outlook 中更改发件人字段

Question

当我在 Outlook 中创建新邮件（或回复）时，如何将表单更改为“to”？ mailItem.Sender 和 SendUsingAccount 不起作用。

命名空间 OutlookAddIn7 { 公共部分类 ThisAddIn { Outlook.Inspectors 检查员；

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {

        inspectors = this.Application.Inspectors;
        inspectors.NewInspector +=
        new Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(SendUsingAccountExample);

    }
    void SendUsingAccountExample(Microsoft.Office.Interop.Outlook.Inspector Inspector)
    {
        Outlook.MailItem mailItem = Inspector.CurrentItem as Outlook.MailItem;
        Outlook.NameSpace session = mailItem.Session;
        Outlook.Accounts accounts = session.Accounts;
        mailItem.SendUsingAccount = Application.Session.Accounts[1];
            //mailItem.Sender = accounts[1].CurrentUser.AddressEntry;
            //Microsoft.Office.Interop.Outlook.Recipient recipient = Application.Session.CreateRecipient(accounts[1].CurrentUser.AddressEntry.Address);
    }

如果您使用的是 Exchange，请设置SentOnBehalfOfName属性。
