Pull Subscription for Room Calendar

Question

Hi,
  I am using windows service to poll the conference from Exchange Room Calendar. To my client request, we have to move for the "PULL SUBSCRIPTION". our existing work flow is completely based on Room not by the user. I tried the Pull subscription
for user it returns the events which is created in user calendar. Is it possible to authenticate  user account (who is having impersonate access) and access Room Calendar's events.
    If it is possible please reply with some example.
Please Advise

Answer 1

As long as you have rights to the Resources calendar folder you should be able to just use Delegate Access
http://msdn.microsoft.com/en-us/library/office/gg274408(v=exchg.80).aspx to do the Pull subscription eg
FolderId RoomCalendarId = new FolderId(WellKnownFolderName.Calendar,"[email protected]");
List<FolderId> fldIds = new List<FolderId>();
fldIds.Add(RoomCalendarId);
Folder Deletions = Folder.Bind(service,WellKnownFolderName.RecoverableItemsDeletions);
EventType[] evEvents = new EventType[] { EventType.Copied, EventType.Created, EventType.Deleted, EventType.Modified, EventType.Moved, EventType.NewMail };
PullSubscription pullsub = service.SubscribeToPullNotifications(fldIds, 30, null, evEvents);
GetEventsResults gEvents = pullsub.GetEvents();
foreach (ItemEvent itmEvent in gEvents.ItemEvents) {
Console.WriteLine(itmEvent.EventType);
Cheers
