Glass Shadows - Ray Tracing

hello ,

how can i let light in through the windows and see the interior shadows when i am looking from exterior ( glass material ) while the raytracing enabled ?

when i enable raytracing and looking from exterior it seems windows do not let light in ( picture 01 ).
when i disable raytracing and looking from exterior windows let the light in. ( picture 02 )
for both option we see the lights coming inside when we look from interior. (picture 03-04)

i use directional light and skylight for the scene.

thank you
