We have a multiple domain one forest model. One Exchnage 2007 server is in each domain (roughly). There islocal IT staff for each domain and they can setup users etc fine in that domain only. My problem is this how do I limit admin staff to adding mailboxes to one Exchange 2007 server only. When they ar put into the Exchange Recipient Admins group they can setup mailboxes on any Exchange 2007 server. I want them to be restricted to just their local server (and even only view there local mailboxes on that server). I know you can do something similar with account and specific OU but I can't limit it down on the Exchange server side??

Hi, This should help you to configure split permissions. Split Permissions Model Reference
