Hide Global list from student accounts in Exchange

This article from Microsoft states that it is possible to control views of the Global Address List on a User by User basis. We could therefore block most of the GAL from student accounts ADED01 through ADED99; by using the Search Control Permission students would only see other student accounts.

When the Search Control permission is used to limit directory access, the global address list (GAL) can be displayed differently on a user-by-user basis. XADM: User's GAL Displayed Differently Based on Search Control

---------------------------------------

Other half truths I found on the web attemting Server side restricted access to Global Address List using Address book Views in Exchange:

If it is OWA ONLY then hiding the users from GAL will be fine.

If it is Outlook, then it will cause a problem.

If the user is hidden from the GAL then Outlook cannot create the profile. It has to be able to see the user.

Furthermore, you will be unable to restrict users from viewing the GAL as that stops Outlook from doing what it needs as well. Source: Stop users browsing Global Address List in Outlook 2003 - Petri.co.il forums by Daniel Petri

• Method 2:
  make a custom GAL that lists nobody... just set some null attributes and set it as the default to be shown... and set the permissions to read only... and they see nothing and can change nothing.
