EWS(Exchange Web服务)获取未授权错误

Question

我在尝试发送或阅读电子邮件时出现未授权(401(错误

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.TraceEnabled = true;
service.TraceFlags = TraceFlags.All;
service.Credentials = new WebCredentials("[e-mail]", "XXXXXXXX");
service.AutodiscoverUrl("[e-mail]", RedirectionUrlValidationCallback);
EmailMessage email = new EmailMessage(service);
email.ToRecipients.Add("[e-mail]");
email.Subject = "Testing from C#";
email.Body = new MessageBody("This is the first email I've sent by using the EWS Managed API");
email.Send();

Answer 1

问题很可能是您为WebCredentials传递了什么凭据取决于Exchange/Active Directory的配置方式。

尝试传入用户名、密码和域的格式：

service.Credentials = new WebCredentials("username", "password", "domain");
