Question

我正在sharepoint中开发一个Provider托管应用程序，用于调用EWS服务。我正在使用托管api。

下面是我的代码，

ClientCredential cc = new ClientCredential("********-****-****-****-********e042", "b/2i******n07QKJ********0uhVVvv*****BUs=");
AuthenticationContext authenticationContext = new AuthenticationContext("https://login.windows.net/mydomain.onmicrosoft.com/");
AuthenticationResult result = authenticationContext.AcquireToken("https://outlook.office365.com/", cc);
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);
service.Credentials = new OAuthCredentials(result.AccessToken);

service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
CalendarView calView = new CalendarView(DateTime.Today, DateTime.Today.AddHours(24));

Mailbox m = new Mailbox("xxxx@xxxxxxxx.onmicrosoft.com");

FolderId CalendarFolderId = new FolderId(WellKnownFolderName.Calendar, m);

FindItemsResults<Appointment> master = service.FindAppointments(CalendarFolderId, calView);

我得到的错误是401未经授权.. 以下是堆栈跟踪，

远程服务器返回错误：（401）未经授权。

描述：执行期间发生了未处理的异常   当前的网络请求。请查看堆栈跟踪了解更多信息   有关错误的信息以及它在代码中的起源。

使用Oauth（ADAL azure活动目录库）401 Unauthorized通过Managed API调用EWS服务
