使用Exchange服务器在asp.net中发送邮件（smtp：outlook.office365.com） [英] Sending Mail in asp.net using Exchange server(smtp:outlook.office365.com)

问题描述

我们在asp.net的邮件系统中工作，我们的客户端使用的是Microsoft Exchange服务器outlook.office365。我们得到System.Net.Mail.SmtpException：操作超时错误。我谷歌所有来源，但没有为我工作。请帮助我们。提前致谢。





btn_click（）{

try {SmtpClient smtp = new SmtpClient（smtp .outlook.office365.com）;

smtp.Host =outlook.office365.com;

smtp.Port = System.Convert.ToInt32（443）;

System.Net.NetworkCredential cred = new System.Net.NetworkCredential（userid，mypwd）;

smtp.Credentials = cred;

smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

smtp.UseDefaultCredentials = false;

smtp.EnableSsl = true;

smtp.TargetName =STARTTLS / outlook.office365.com;

MailMessage msg = new MailMessage（）;

msg.From = new MailAddress（frommailid ，username）;

msg.To.Add（new MailAddress（[e-mail]））;

msg.Subject =测试;

msg.Body =测试邮件;

smtp.Timeout = 60000;

smtp.Send（msg）;

} catch（例外情况）

{

抛出ex;

}

}

解决方案

MailMessage msg = new MailMessage（）;

msg.To .Add（新邮件地址（[e-mail]，SomeOne））;

msg.From =新邮件地址（[e-mail]，你）;

msg.Subject =这是一个测试邮件;

msg.Body =这是使用Exchange OnLine的测试消息;

msg .IsBodyHtml = true;



SmtpClient客户端=新的SmtpClient（）;

client.UseDefaultCredentials = false;

client.Credentials = new System.Net.NetworkCredential（您的用户名，您的密码）;

client.Port = 587; //如果587被阻止你可以使用端口25（我的是！）

client.Host =smtp.office365.com;

client.DeliveryMethod = SmtpDeliveryMethod。网络;

client.EnableSsl = true;

尝试

{

client.Send（msg）;

lblText.Text =消息已成功发送;

}

catch（例外情况）

{

lblText.Text = ex.ToString（）;

}

System.Net.Mail.MailMessage message = new System.Net。 Mail.MailMessage（）;



//从注册表中读取电子邮件

string fromEmail = Registery.fromAddress;



//从注册表中读取密码

string fromPassword = Registery.password;



//读取地址来自registery

//从注册表中读取传出服务器的端口

int port = Convert.ToInt32（Registery.port）;



//读取来自registery的enableSSL是true还是false

bool enableSSL = Convert.ToBoolean（Registery.enableSSL）;



条消息.From = new MailAddress（fromEmail.ToString（））;

message.To.Add（toAddress.ToString（））;

message.Subject = ServiceName + + status.ToString（）;

message.Body =服务名称：+ ServiceName + Environment.NewLine +状态：+ status.ToString（）;

message.IsBodyHtml = true;

message.DeliveryNotificationOptions = DeliveryNotificatio nOptions.OnFailure;



/// smtp在注册表配置的服务器和端口

SmtpClient smtpClient = new SmtpClient（smtpServer，port）;



///启用安全连接需要ssl。对于gmail服务器必须为true，对其他服务器必须为false。

smtpClient。 EnableSsl = enableSSL;



smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;

smtpClient.UseDefaultCredentials = false;

smtpClient.Credentials = new NetworkCredential（fromEmail，fromPassword）;

smtpClient.Send（message）;
