c# 以编程方式从 Exchange 服务器读取电子邮件

当您在网络上搜索时，您会找到“如何以编程方式阅读电子邮件”的非常简单的答案......所有网站都解释了大部分与此页面相同的内容。http://omegacoder.com/?p=454

// depends from Exchange server version      
        service.Credentials = new NetworkCredential("MDR", "password", "zzz");
        service.AutodiscoverUrl("[email protected]");
        object o = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        foreach (Item item in findResults.Items)
        {
            Console.WriteLine(item.Subject);
        }

当执行 autodiscoverURL 行时它会失败。该错误显示“无法找到自动发现服务。”

所以我进一步谷歌搜索并找到了来自微软的这个网站在这里您可以测试您的邮件服务器...... 当我传递参数时，出现以下错误......

但我还是不明白问题出在哪里？我需要向 DNS 添加记录吗？有人可以帮忙吗？

如果您已经知道 Exchange 服务器的地址，则不一定需要使用自动发现。请尝试以下操作（有关更多信息，请查看here:

service.Url = new Uri("https://hostname/EWS/Exchange.asmx");

将“主机名”替换为您的 Exchange 服务器的主机名。
