[英]This is the code I use to send an email using the service of Exchange Server
[英]Can not programmatically send email using web service of MS Exchange Server 2010 SP2
我有一個應用程序(C#),該應用程序使用MS Exchange Server 2010 SP2的Web服務發送電子郵件。 以前工作正常。 但是,就在2周前,我遇到了問題。 該代碼有時可以發送電子郵件,但有時不能。 我收到以下錯誤消息(最后顯示完整的錯誤消息)。
The request failed. Unable to connect to the remote server
我的代碼如下。
string ewsUrl = "https://xxxx.xxxx.com/ews/Exchange.asmx";
string userName = "xxxx";
string password = "xxxx";
string to = "xxxx@xxxx.com";
string cc = "xxxx@xxxx.com";
ExchangeService service = new ExchangeService();
service.Url = new Uri(ewsUrl);
service.UseDefaultCredentials = true;
service.Credentials = new WebCredentials(userName, password);
EmailMessage message = new EmailMessage(service);
message.Subject = subject;
message.Body = bodyHtml;
message.ToRecipients.Add(to);
message.CcRecipients.Add(cc);
message.SendAndSaveCopy();
我不知道出了什么問題。 我認為該網址是正確的,並且可以在某個時間而不是其他時間正常工作。 我在互聯網上進行搜索,但沒有找到任何解決方案。 這與服務器配置有關嗎? 我已經與我的IT部門進行了交談,但似乎他對Web服務一無所知。 請幫我。 完整的錯誤消息如下。

{ return true; };
我認為您需要在message.CcRecipients.Add(cc);
之間添加以上代碼message.CcRecipients.Add(cc);
和message.SendAndSaveCopy();
