C# 无法使用SMTP服务器和AJAX发送邮件

我是asp.NETMVC新手。我正在尝试在asp.NETMVC中使用SMTP服务器和AJAX发送带有附件的邮件。邮件无法发送

HomeController.cs

public JsonResult SendMailToUser()
    {
        bool result = false;
        result = SendEmail("Receiver_mail", "Test", "<p>Hi abc,<br/>This message is for testing purpose. So don't be upset.<br/>Kind Regards,<br/>abc</p>");
        return Json(result, JsonRequestBehavior.AllowGet);
    }
    public bool SendEmail(string toEmail, string subject, string emailBody)
    {
        try
        {
            string senderEmail = System.Configuration.ConfigurationManager.AppSettings["Sender_Mail.com"].ToString();
            string senderPassword = System.Configuration.ConfigurationManager.AppSettings["Outlook@123"].ToString();

            SmtpClient client = new SmtpClient("smtp-mail.outlook.com", 587);
            client.EnableSsl = false;
            client.Timeout = 100000;
            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            client.Credentials = new NetworkCredential(senderEmail, senderPassword);

            MailMessage mailMessage = new MailMessage(senderEmail, toEmail, subject, emailBody);
            mailMessage.IsBodyHtml = true;
            mailMessage.BodyEncoding = UTF8Encoding.UTF8;

            client.Send(mailMessage);

            return true;
        }
        catch (Exception ex)
        {
            return false;
        }

    }

                mail.Recipients.Add(user.PrimarySmtpAddress);
                mail.Recipients.ResolveAll();

            }
        }
        catch (Exception ex)
        {

        }
    }

在Outlook 2007设置中是否需要执行任何操作？outlook 2007在Exchange server上运行

谢谢你的建议！我找到了以下解决方案。它在localhost中工作得很好，但在发布后失败！请建议一条出路

您的问题是什么？有什么例外吗？哪一个？哪一行代码？您是否调查Exchange日志文件？是否存在任何错误/警告？他们有任何代码或其他东西，我们可以用谷歌搜索吗？我在点击按钮后在网页上收到了一条警告信息，称为“成功”，但收件人端没有收到邮件。

alert（“Success”）。您的控制器操作
SendMailToUser
始终返回状态代码200，如我所见。再说一遍：你的问题是什么？有什么例外吗？哪一个？哪一行代码？您是否调查Exchange日志文件？是否存在任何错误/警告？他们有任何代码或其他东西，我们可以用谷歌搜索吗？@Nelson Kingsley，你是否尝试将邮件发送到其他电子邮件地址而不是outlook？只需检查你的发送邮件代码是否正常
