我在 Item_Write 事件处理程序中为会议请求设置取消检查，因为如果我在 Item_Send 中将取消设置为 true，会议窗口将关闭。我正在尝试做的是提示用户他们有通常会使用功能区中的自定义按钮进行处理的收件人（按钮详细信息对我的问题并不重要）。无论如何，当我尝试取消 Item_Write 事件时，无论如何都会发送会议通知。无论我尝试什么，即使我将 ref Cancel 设置为 true，我也无法阻止会议通知发出。如果我取消 Item_Send 然后窗口关闭，这不是用户想要的。此时我唯一能想到的可能就是 requestDetailsRegion.SaveRequestDetailsToLocalOutlookItemProperties()，它将自定义表单区域字段属性保存到 AppointmentItem 上定义的自定义属性，正在触发 Application_Item_Load 事件，这以某种方式提示 Outlook 发送会议邀请通知，就好像它处于待处理状态一样。我在 Outlook 2010 中运行它。提前谢谢你。

这是一些示例代码：

  void Item_Write(ref bool Cancel)        
 {    

            Cancel = CancelInvite(Cancel);                
 }

        private bool CancelInvite(bool Cancel)
        {

            Inspector activeInspector = Globals.ThisAddIn.Application.ActiveInspector();
            WindowFormRegionCollection formRegions = Globals.FormRegions[activeInspector];
            RequestDetailsFormRegion requestDetailsRegion = formRegions.RequestDetailsForm;


                // Add request form details to meeting item.
                requestDetailsRegion.SaveRequestDetailsToLocalOutlookItemProperties();

                // Checking if there's an incomplete form request pending submission
                if (requestDetailsRegion.txtFileName_Hidden.TextLength == 0 &&
                    appointmentItem != null && appointmentItem.MeetingStatus != OlMeetingStatus.olMeetingCanceled)
                {
                    Persons meetingRecipients = new Persons();



                    foreach (Outlook.Recipient recipient in appointmentItem.Recipients)
                        if (recipient.Address != activeInspector.Session.CurrentUser.Address)
                            meetingRecipients.Add(new MeetingRecipient(recipient));

                    if (meetingRecipients.ContainsSpecialRecipients)
                    {                           
                        CustomDialog customDialog = new CustomDialog();
                        customDialog.OkButtonText = messageBoxTextStatusOK;
                        customDialog.CancelButtonText = messageBoxTextStatusCancel;

                        DialogResult dialogResult = customDialog.ShowDialog();

                        if (dialogResult == DialogResult.Cancel)
                        {
                            Cancel = true;
                        }
                        else
                        {
                            Cancel = false;
                        }    

                        customDialog.Close();
                    }
                }                

            return Cancel;
        }

   public void SaveRequestDetailsToLocalOutlookItemProperties()
        {
            if (this.OutlookItem is Outlook.AppointmentItem)
            {
                Outlook.AppointmentItem appointmentItem = (Outlook.AppointmentItem)this.OutlookItem;

                // Checking if organizer already cancelled meeting. If so, then no need to update apppointment item properties.
                if (appointmentItem.MeetingStatus != Outlook.OlMeetingStatus.olMeetingCanceled)
                {

                    appointmentItem.ItemProperties[RequestSubmitted].Value = chkSubmitted.Checked; // Hidden 
                    appointmentItem.ItemProperties[Filename].Value = txtFileName_Hidden.Text; // Hidden

                    appointmentItem.ItemProperties[ReasonForVisit].Value = txtReason.Text;

   // SPARING SIMILAR LINES OF CODE

    ...
                    chkSaved.Checked = true;
                }
            }

您从未将 (ref) Cancel 参数设置为 true

void Item_Write(ref bool Cancel)        
 {    

            this.cancelInviteResult = CancelInvite(Cancel);
            Cancel = this.cancelInviteResult; 
 }
