Domain administrators can actively manage the GAL by adding or removing users as needed. As mentioned, it may be worthwhile for a domain administrator to limit GAL entries to actual employees or users on the domain, excluding things like aliases or generic mailboxes that are used for departments, such as Billing or HR departments.
To change a user's GAL setting, you'll first want to be logged in as a domain administrator. From there, do the following:
- Go to the Domain Settings.
- Select Accounts from the navigation menu and ensure that the Users tab is highlighted.
- Click on the user to edit their settings.
- On the User card, enable or disable the Show in Global Address List setting as needed.
- Be sure to save the changes.
