HiWe currently have 3 Admin groups in our Exchange 2003 organisation, which reflects the geography of our company. Each location has rights over its own Exchange Admin group, and junior Helpdesk staff have view-only rights over their Exchange Admin group.We are shortly moving to Exchange 2007, and need to give Senior Helpdesk staff rights to create/modify mailboxes, and junior Helpdesk staff view only access. However, from what I've seen, Recipient Administrators and View-Only Administrators are rights you can have across the whole org only, you cannot break this down into servers.Can someone confirm?
