是用C#开发的邮件发送功能总是出现如下错误“The request failed. 远程服务器返回错误: (401) 未经授权”
代码如下：

public class ExchangeEmail
{
public ExchangeService service;
public ExchangeEmail()
{
service = new ExchangeService(ExchangeVersion.Exchange2010);
service.Credentials = new WebCredentials("mailAddress", "PWD", "Domain");
service.Url = new Uri("https://domain/ews/exchange.asmx");
service.TraceEnabled = true;
service.TraceFlags = TraceFlags.All;
}
Logger log = new Logger();
public bool SendEmail(string SendTo, string EmailSubject, string EmailBody, string CCTo = "", string AttachmentName = "", byte[] AttachStream = null)
{
EmailMessage email = new EmailMessage(service);
try
{
if (SendTo.IndexOf(";") > 0)
{
string[] EmailArray = SendTo.Split(';');
foreach (string item in EmailArray)
{
email.ToRecipients.Add(item.TrimEnd().TrimStart());
}
}
else
{
email.ToRecipients.Add(SendTo.TrimEnd().TrimStart());
}
if (CCTo != "")
{
if (CCTo.IndexOf(";") > 0)
{
string[] EmailArray = CCTo.Split(';');
foreach (string item in EmailArray)
{
email.ToRecipients.Add(item.TrimEnd().TrimStart());
}
}
else
{
email.CcRecipients.Add(CCTo.TrimEnd().TrimStart());
}
log.Log("Add CC Recipient " + CCTo + " Successfully");
}
if (AttachmentName != "" && AttachStream != null)
{
email.Attachments.AddFileAttachment(AttachmentName, AttachStream);
}
email.Subject = EmailSubject;
email.Body = new MessageBody(EmailBody);
email.Body.BodyType = BodyType.HTML;
email.Send();
return true;
}
catch (Exception)
{
return false;
}
finally
{
email.ToRecipients.Clear();
email.CcRecipients.Clear();
email.BccRecipients.Clear();
}
}
}
