使用Exchange Web服务阅读电子邮件 [英] read email using exchange web services

问题描述

这是我的情况：我必须阅读来自Exchange 2010 sp2帐户的电子邮件。我必须使用Exchange Web服务，POP3和IMAP被阻止。我必须在人们只能通过Intranet通过Web浏览器访问其帐户的环境中测试我的应用程序。我无法直接将应用调试到此Intranet。我有以下代码段可访问帐户：

This is my scenario: I have to read email from exchange 2010 sp2 accounts. I have to use Exchange Web Services, POP3 and IMAP are blocked. I have to test my app in an environment where people can access their accounts through a web browser only in the intranet. I can't debug my app directly to this intranet. I have this snippet to access an account:

private void Dowork()
{
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);

    string dominio = "domain";
    string usuario = "user";
    string password = "password";

    service.Credentials = new NetworkCredential(usuario, password, dominio);

    string url = usuario + "@" + dominio + ".com";

    service.AutodiscoverUrl(url, RedirectionUrlValidationCallback);
    //service.AutodiscoverUrl(url);

    FindItemsResults<Item> findResults = service.FindItems(
       WellKnownFolderName.Inbox,
       new ItemView(10));

    string content = string.Empty;

    foreach (Item item in findResults.Items)
    {
        EmailMessage email = EmailMessage.Bind(service, item.Id);
        email.Load();

        content += item.Subject + "\n";
        content += email.From.Address + "\n";
        content += email.Body + "\n\n";

        //Console.WriteLine(item.Subject);
        //Console.WriteLine(email.From.Address);
        //Console.WriteLine(email.Body);
    }

    string result = content;
}

// Create the callback to validate the redirection URL.
static bool RedirectionUrlValidationCallback(String redirectionUrl)
{
    // Perform validation.
    return (redirectionUrl == "https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml");
}

如果我使用此行：

service.AutodiscoverUrl(url);

我收到此错误：

自动发现阻止了可能不安全的重定向到 https://autodiscover.colpatria.com/autodiscover/autodiscover。 xml 。要允许自动发现遵循重定向，请使用AutodiscoverUrl（string，AutodiscoverRedirectionUrlValidationCallback）重载。

"Autodiscover blocked a potentially insecure redirection to https://autodiscover.colpatria.com/autodiscover/autodiscover.xml. To allow Autodiscover to follow the redirection, use the AutodiscoverUrl(string, AutodiscoverRedirectionUrlValidationCallback) overload."

因此方法 RedirectionUrlValidationCallback 已实现，我不确定该URL是否正确。事实是我收到此错误：

So the method RedirectionUrlValidationCallback was implemented, I'm not sure if the url is right. The fact is I'm getting this error:

找不到自动发现服务。

"The Autodiscover service couldn't be located".

是否可能没有正确配置自动发现？我不是交易所管理员，我怎么知道自动发现是否有效？我需要参数来告诉交易所管理员必须配置此功能。谢谢您的帮助。

Is possible that Autodiscover is not configured properly?? I'm not the exchange administrator, how can I know if autodiscover works?? I need arguments to tell exchange administrators this feature must be configured. Thanks for any help.

推荐答案

这是一篇旧文章，我认为我应该针对报告的错误提供完整的示例解决方案。只需将 service.AutodiscoverUrl（ [e-mail]）; 替换为 System.Uri（ https://mail.somedomain.org/ews/Exchange.asmx ）；

This is a old post I thought I'd put in a full example solution for the error reported. Simply replace service.AutodiscoverUrl("[e-mail]"); with System.Uri("https://mail.somedomain.org/ews/Exchange.asmx");

完整的代码块

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
                service.Credentials = new WebCredentials("someuser", "somepassword");
                //service.AutodiscoverUrl("[e-mail]");
                service.Url = new System.Uri("https://mail.somedomain.org/ews/Exchange.asmx");
