Question : Exchange 2003 - Restrict modification of distribution groups in the Global Address List from Outlook

I run Exchange 2003 and I am finding that Outlook users can add or remove members of a distribution group in the global address list (GAL). For example, I have a group called "sales" ([email protected]) that distributes to a specific group of people. Well, if Jennifer Receptionist opens her address book in Outlook and picks the Global Address List from the drop down, she can see the "sales" group and can add or remove members. Not a good thing. How do I restrict access to the modification of those groups in the GAL?

Check the security permission: Open Exchange System Manager>>Recipients>>All Global Address Lists, then check the security under properties and make sure that everyone permission is not R/W!
