Word Send To GW recipient

i am having trouble sending a doc to a gw recipient. error from Windows
Messaging : The Object could not be found. I found TID 10094741
that states this won't work in term server environment except in Word
pad, IE, maybe some others... But this TID is from back in 04. Does
anyone know if this is still valid, and I still can't send to a GW
recipient through Word and Excel, maybe PowerPoint?
