问题描述

Hi Guys,

我使用下面的代码来检索5个用户的日历事件;但最终会出现以下错误

I am using below code to retrieve calendar events of 5 users; but end up with error as below

// Exchange连接
ExchangeService服务=新的ExchangeService（ExchangeVersion.Exchange2010）;
//替换为正确的用户名和密码
service.Credentials = new WebCredentials（""，""）;
service.Url = new Uri（" https://outlook.office365.com/ews/exchange.asmx"）; // Office 365 Exchange API URL（如果您使用的是本地Exchange安装，则将其替换为本地服务器URL）

//本周
DateTime startDate = DayPilot.Utils.Week.FirstDayOfWeek （）;
DateTime endDate = startDate.AddDays（7）;

// ExchangeService Service = null;
//加载默认日历
CalendarFolder calendar = CalendarFolder.Bind（service，WellKnownFolderName.Calendar，new PropertySet（））;

//加载事件
CalendarView cView = new CalendarView（startDate，endDate，50）;
cView.PropertySet = new PropertySet（AppointmentSchema.Subject，AppointmentSchema.Start，AppointmentSchema.End，AppointmentSchema.Id）;
FindItemsResults<约会> appointment = calendar.FindAppointments（cView）;

// Exchange connection ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010); // replace with proper username and password service.Credentials = new WebCredentials("", ""); service.Url = new Uri("https://outlook.office365.com/ews/exchange.asmx"); // Office 365 Exchange API URL (replace it with a local server URL if you are using a local Exchange installation) // this week DateTime startDate = DayPilot.Utils.Week.FirstDayOfWeek(); DateTime endDate = startDate.AddDays(7); //ExchangeService Service = null; // load the default calendar CalendarFolder calendar = CalendarFolder.Bind(service, WellKnownFolderName.Calendar, new PropertySet()); // load events CalendarView cView = new CalendarView(startDate, endDate, 50); cView.PropertySet = new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End, AppointmentSchema.Id); FindItemsResults<Appointment> appointments = calendar.FindAppointments(cView);

推荐答案

客户端程序提供的凭据无权访问资源，这是401错误的含义。 

The credentials presented by the client program does not have authority to access the resource is what the 401 error means.
