Exchange 2013 standard is installed in our environment. Created an Ou with the name Chicago. Around 50 users are in this OU.
I want users in this Ou should send & receive mail to each others only. They can't send to other users in different OU.
Also in the address list they should only see their address that is there in their OU only.they can't view other mail ids.
Exchange is configured for internally only
How can I configure.
