c++ - Finding child window fails on empty pane

Question

My app is recursively enumerating child windows of certain other process to get handle to a certain button. Traversing windows is done using FindWindowEx and EnumChildWindows functions. This works fine but until my code encounters a pane control as shown in picture. That pane window can not be accessed using FindWindowEx with "Meeting Tools" parent window or using EnumChildWindows. FindWindowEx returns NULL and EnumChildWindows does not enter callback at all. Attached picture is captured using "Inspect" application provided by Microsoft, so it's certainly possible to traverse window tree beyond pane control. But how can this be done?

Edit: Microsoft Spy++ also fails to display any child windows under "Meeting Tools".
