我想使用EWS Managed API 2.2和从Office javascript api 1.1 中的Office.context.mailbox.getCallbackTokenAsync()方法 获得的身份验证令牌 发送邮件。我也使用 asp.net web api 项目来调用 ews 函数。执行 messge.Send()方法时发生 execption 。这是代码示例和错误

public class HomeController : ApiController
        {
            string EwsUrl = "https://outlook.office365.com/EWS/Exchange.asmx";
            string rawToken = "eyJ0eXAiOiJKV1QiLCJhbGciO……WER";

            public void GetSendMailResponse()
            {
                ExchangeService service = new ExchangeService();
                service.Credentials = new OAuthCredentials(rawToken);
                service.Url = new Uri(EwsUrl);

                // Create an email message and identify the Exchange service.
                EmailMessage message = new EmailMessage(service);

                // Add properties to the email message.
                message.Subject = "Interesting";
                message.Body = "The merger is finalized.";
                message.ToRecipients.Add("aaa@aaa.com");
                message.Send();
            }
        }

完全例外

您从邮件应用程序中的 getCallbackTokenAsync 获得的令牌不能用于发送邮件。您只能检索当前项目或当前项目上的附件。请参阅http://msdn.microsoft.com/en-us/library/office/jj984589(v=office.1501401).aspx上的备注。
