选择启动Outlook时显示的配置文件提示

Question

我想使用c＃脚本获取Outlook，但始终显示“选择配置文件”提示。在控制面板>>邮件>> Pofile中，将我的“ Outlook”配置文件设置为默认配置。如果我启动Outlook，则代码可以正常运行。如果我启动Outlook并关闭它，有时会出现提示。如果我启动Outlook并将其终止，则在运行代码时会显示提示。

我不知道如何以编程方式避免出现这种提示。请在下面查看我的代码：

public static void SendMail(string ToStr, string CCStr, string BCCStr, string Subject, string Body, string AttachmentStr, string AccountUserName = "")

        OL.MAPIFolder MFold = null;
        OL.MailItem MI = null;
        OL.Recipients oReci = null;

        bool StillRunning = false;
        bool FoundAccount = false;
        string[] To = ToStr.Split(';');
        string[] CC = CCStr.Split(';');
        string[] BCC = BCCStr.Split(';');
        string[] Attachment = AttachmentStr.Split(';');
