We have two domain in our organization.
valley.com
int.valley.com
There are 120 mailboxes and users under int.valley.com. I have setup an account to manage only the mailboxes (int.valley.com\users) in this child domain. But when I logged in to the ECP of Exchange 2013 I can see all the other mailboxes as well. I want to the child domain admin to see only the child domain mailboxes.
Please help.
