Hello I wished to know if it is possible between two Exchange 2010 in two different areas but in the same forest to hide the contacts of an OU specific to some user does not see addresses (address book) of some other users by example. And this from OWA & Outlook from the client ... Thank you

Hi, Can u more elaborate what u need? I think you want to segregate address lists for your users. I also think that you are non-english speaker so I m having difficulties in understanding what u r trying to ask.
