Microsoft.Exchange.WebServices.Data.ServiceResponseException:连接失败.稍后再试

问题描述

我有一封相当简单的电子邮件，需要使用Exchange服务器发送.这在本地有效，但是在发布到服务器时失败.这是我的代码，它建立了到交换服务器的链接:

I have a fairly simple email that I need to send using Exchange server. This works locally, but fails when I publish to the server. Here is my code establishing the link to the exchange server:

var服务=新的ExchangeService(ExchangeVersion.Exchange2010_SP2);service.UseDefaultCredentials = true;service.AutodiscoverUrl(Config.GetGroupMailbox()，RedirectionUrlValidationCallback);

var service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);service.UseDefaultCredentials = true;service.AutodiscoverUrl(Config.GetGroupMailbox(),RedirectionUrlValidationCallback);

设置完字段后，我只是简单地调用.Send().

After setting the fields I am simply calling .Send() with no success.

这是堆栈跟踪:

推荐答案

我找到了问题并解决了.问题出在与正在连接或尝试连接的用户有关.

I found the issue and resolved. The issue was with the user that was connecting, or attempting to connect.

我已将服务设置为使用默认设置:service.UseDefaultCredentials = true;意味着它将在用户运行进程时尝试连接.

I had set the service to use default setting:service.UseDefaultCredentials = true;meaning that it would try to connect as the user running the process.

当我用实际的用户名和密码替换所有内容时，一切正常:

When I replaced that with actual user id and password everything worked:

service.UseDefaultCredentials = false;
service.Credentials = new WebCredentials(Config.GetEmailConnectionUserID(),
                                         Config.GetEmailConnectionPassword());
