c# - 在 EWS 中访问房间日历返回 "No mailbox with such guid"

Question

我正在尝试使用 Microsoft Exchange (EWS) API 从房间共享日历中获取 session 列表，但它返回此错误:没有具有此类 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

任何想法可能是错误的？

Answer 1

确保您正在使用的用户

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

是拥有自己邮箱的许可用户，已被授予访问相关共享邮箱的权限。
