MS Exchange Web-Services: How to get items with 'Flag' set? - exchangewebservices

Question

Does anyone know how to get all the items that are flagged inside the Inbox using Microsoft Exchange Web-Services?
Apparently they are neither inside Tasks folder (even though they appear there in Outlook), nor do they have IsReminderSet set to true.
Following attempts either return only appointments or true tasks only, but not flagged messages:
var msgsView = new ItemView(100);
var msgsFilter = new SearchFilter.IsEqualTo(ItemSchema.IsReminderSet, true);
var flagged = exSvc.FindItems(WellKnownFolderName.Inbox, msgsFilter, msgsView);
or
var taskView = new ItemView(100);
var tasks = exSvc.FindItems(WellKnownFolderName.Tasks, taskView);
neither work.

I know this question is old, but I just found list sample code which looks like it might do the trick (I haven't tested it myself yet)
source: http://independentsoft.de/exchangewebservices/tutorial/findmessageswithflag.html
IsEqualTo restriction1 = new IsEqualTo(MessagePropertyPath.FlagStatus, "1"); //FlagStatus.Complete
IsEqualTo restriction2 = new IsEqualTo(MessagePropertyPath.FlagStatus, "2"); //FlagStatus.Marked
Or restriction3 = new Or(restriction1, restriction2);
FindItemResponse response = service.FindItem(StandardFolder.Inbox
, MessagePropertyPath.AllPropertyPaths, restriction3);
for (int i = 0; i < response.Items.Count; i++)
{
if (response.Items[i] is Message)
{
Message message = (Message)response.Items[i];
Console.WriteLine("Subject = " + message.Subject);
Console.WriteLine("FlagStatus = " + message.FlagStatus);
Console.WriteLine("FlagIcon = " + message.FlagIcon);
Console.WriteLine("FlagCompleteTime = " + message.FlagCompleteTime);
Console.WriteLine("FlagRequest = " + message.FlagRequest);
Console.WriteLine("-----------------------------------------------");
}
}
