Question

我的办公室里有一个交换在线服务365，
我想使用不同的方法将电子邮件发送到其他人邮箱

然后我找到了Exchange Web Services，所以我试着做一个基本的例子：

class Program
{
    static void Main(string[] args)
    {
        //note that there no option for exchange server 2016 (my exchange online use exchange server 2016), so i use the default option  
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);   

        service.Credentials = new WebCredentials("user@domain.com", "myPassword");
        service.UseDefaultCredentials = false;

        //for log purpose
        service.TraceEnabled = true; 
        service.TraceFlags = TraceFlags.All;

        service.AutodiscoverUrl("user@domain.com", RedirectionUrlValidationCallback);

        EmailMessage email = new EmailMessage(service);
        email.ToRecipients.Add("user2@domain.com");
        email.Subject = "HelloWorld";
        email.Body = new MessageBody("This is the first email I've sent by using the EWS Managed API.");
        email.Send();

    }

    private static bool RedirectionUrlValidationCallback(string redirectionUrl)
    {
        // The default for the validation callback is to reject the URL.
        bool result = false;

        Uri redirectionUri = new Uri(redirectionUrl);

        // Validate the contents of the redirection URL. In this simple validation
        // callback, the redirection URL is considered valid if it is using HTTPS
        // to encrypt the authentication credentials. 
        if (redirectionUri.Scheme == "https")
        {
            result = true;
        }
        return result;
    }
}

并且AutodiscoverUrl中存在异常，如下所示：

Microsoft.Exchange.WebServices.Data.ServiceXmlDeserializationException: 'The 
expected XML node type was XmlDeclaration, but the actual type is Element.'

在我搜索了一段时间之后，它说交换机无法找到我的域名，我的交换机在线设置很好，我可以发送电子邮件，通过Outlook web访问我的邮箱中的其他人添加预约

我已经将我的名字服务器更改为
ns1.bdm.microsoftonline.com
ns2.bdm.microsoftonline.com

但仍无法解决我的问题..

是否有一些我失踪的设置？ THX ..

Answer 1

而不是使用

 service.AutodiscoverUrl("user@domain.com", RedirectionUrlValidationCallback);

试

 service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");

我建议你设置

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

到Office365的最高枚举，而不是最低，除非您尝试支持Exchange 2007。

Exchange Web服务无法连接
