在EWS中访问房间日历会返回“没有此类guid的邮箱”

Question

我正在尝试使用Microsoft Exchange（EWS）API从房间共享日历中获取会议列表，并且它返回此错误：没有带有此类guid的邮箱

var service = new ExchangeService();
service.Credentials = new NetworkCredential("username", "password");
service.Url = new Uri("exchangeUrl");

var startDate = DateTime.Today;
var endDate = DateTime.Today.AddDays(1);
var cv = new CalendarView(startDate, endDate);
var mailboxToAccess = "room_email_address@mycompany.com";
var calendarFolderId = new FolderId(WellKnownFolderName.Calendar, mailboxToAccess);
var appointments = service.FindAppointments(calendarFolderId, cv); // << Exception happens here

任何想法可能出错？

Answer 1

确保您使用的用户

service.Credentials = new NetworkCredential（＆＃34; username＆＃34;，＆＃34; password＆＃34;）;

具有自己邮箱的许可用户是否已被授予对相关共享邮箱的访问权限。

Answer 2

如果要从应用程序端访问Outlook邮箱，请使用此功能。
语言：C＃

service.Credentials = new NetworkCredential("username", "password");   
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
