I need to get the reading pane window handle, when it is created after the
user clicks the menu as "view -reading Pane - right".
I am able to get the handle of it, if this option is already set as "right"
or "bottom"
But if the preview pane option is "off", when the outlook initially opened,
on the clcik of the option, I am not getting the window handle.
I am getting it, if I close the reading pane and open it again.

First time, when the reading pane or to-do-bar is created with menu click, I
am not getting the window handle.

Can anyone please help me in this direction? How to get the handle at the
first time?
Thanks
