        tbxTo.BulkText = "[email protected]";

        Thread.Sleep(2000);
        window.Close();
    }

Answer 1

The "second window" is in the same process id, so with that you can't simply use the .GetWindow() method.

For MDI applications you should use MdiChild(), or if it is a modal window, use .ModalWindow() on the parent window, or go back to the application then use Window() to get the window.

I would add that getting the window by it's title is not recommended, since that will change as you type the new title of the e-mail.
