EWS Search Appointments By Required Attendees

I am trying to search appointment by Required Attendees...but below code is not working. Any idea on how to implement this search. Thanks in advance

var Filter = new SearchFilter.SearchFilterCollection(LogicalOperator.Or)
        {
            new SearchFilter.ContainsSubstring(AppointmentSchema.RequiredAttendees, mailAddress),
            new SearchFilter.ContainsSubstring(AppointmentSchema.OptionalAttendees, mailAddress),
        };
            var view = new ItemView(1000)
            {
                PropertySet = new PropertySet(BasePropertySet.FirstClassProperties)
            };
FindItemsResults<Item> results = ews.FindItems(WellKnownFolderName.Calendar, Filter, view);

That isn't a supported filter because the Attendees (or really just the recipients) is a collection and SearchFilters can't be used on those type of structures. The closest thing you can do is use AQS and search on the participants

string queryString = "Participants:[email protected]";
FindItemsResults<Item> results = ews.FindItems(WellKnownFolderName.Calendar, queryString, view);

That will Participants includes optional attendees but you can just filter the excess appointments you get back at the client side.
