title: EWS Managed API find items with ItemID
body: <p>I am trying to find items from deleted items folder given the items unique id</p>
  
  <pre><code>ItemId id = new ItemId("zTK6edxaI9sb6AAAQKqWHAAA");
  SearchFilter.IsEqualTo filter = new SearchFilter.IsEqualTo(ItemSchema.Id, id);
  ItemView view = new ItemView(10);
  view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties, EmailMessageSchema.Subject);
  FindItemsResults&lt;Item&gt; results = _ExchangeService.FindItems(WellKnownFolderName.DeletedItems, filter, view);
  Console.WriteLine(results.TotalCount);
  </code></pre>
  
  <p>This code returns an exception saying: </p>
  
  <pre><code>Validation failed.
  Parameter name: searchFilter
  </code></pre>
  
  <p>The same code works if I search for a message with Subject.</p>
