Network administration - Exchange's address list is a series of addresses that can be browsed by various types of Exchange recipients to retrieve information from someone. The address list in Exchange 2007 is the Global Address List, the custom Address List or the Offline Address Book. In Part 1 of this series, we will introduce you to Global Address Lists. In the following sections of the series, we will introduce you to custom Address Lists and how to create and manage them. In the final section, we will introduce Offline Address Books details.

Global Address Lists

When installing Exchange 2007, you will have a Global Address List (GAL), called Default Global Address List, which is a collection of all users, contacts, distribution groups, public folders and System mailbox in your Exchange organization as shown in Figure 1.

Create a Global Address Lists using New-GlobalAddressList

If you're looking for additional Global Address Lists (GALs), here are some things to keep in mind:

One reason to create multiple GALs is if your Exchange organization supports multiple companies, where you want to ensure users can only see recipients in the same company.

To create a new GAL, you need to use the Exchange Management Shell command with the New-GlobalAddressList command, and define a name for the GAL using the Name parameter. Any of the following parameters can be added to define who will appear as a member of the GAL

In Figure 2 you can see how to use the Exchange Management Shell to create two new Global Address Lists, the first Global Address List called "Community Day Attendees" is based on the CustomAttribute3 value and the Title attribute value. The second Global Address List called "Community Day Organizers" is only based on CustomAttribute3 values .

The newly created GAL will appear in the Exchange Management Console, as shown in Figure 3.

When creating a new GAL, it will not be settled until you upgrade the GAL with Exchange Management Shell with the Update-GlobalAddressList command.

Update-GlobalAddressList

You need to upgrade the GAL with Exchange Management Shell with the Update-GlobalAddressList command to:

In the given example, we created a new GAL called " Community Day Organizers ". Using Exchange Management Shell is quite easy for you to get a list of recipients who are members of that GAL. Before updating the GAL, you can see in Figure 4 that the GAL is still empty. After upgrading the GAL, you may see that the GAL has been settled.

Figure 4: Update-GlobalAddressList

When running Update-GlobalAddressList, Exchange will update all recipients in Active Directory to reflect the fact that it is a member of that GAL by upgrading the property named showInAddressBook . In Figure 5 you can see that User A will only appear in the custom Address List named All Users and the default GAL. After updating the GAL Community Day Attendees, as shown in Figure 6, the properties are upgraded to the GAL Community Day Attendees group , as shown in Figure 7.

Table 1: Terms of GAL

You can use AdsiEdit to retrieve terms from the Community Day Attendance Team to open the GAL's default address list and public day organizer. Open AdsiEdit and connect Configuration Partition, find Configuration, Services, Microsoft Exchange, Name of your organization , Address Lists Containers, All Global Address Lists. Right-click on the required GAL and change the permissions as shown in Figure 8.

Figure 8: Refuse to open the address list clause

Using the Exchange Management Shell to prevent you from opening the GAL, you need to use Exchange Management Shell with the Set-ADPermission command. In Figure 9, you can see that the shell can be used to deny the right to open the GAL named Community Day Organizer to a universal security group named community day attendees.

Figure 9: Add-ADPermission

When user A signs in to the domain and opens Microsoft Office Outlook, this user will see the GAL named Community day attendee as shown in Figure 10. Here, members of the Community Day Organizers will see GAL called Community Day Organizers and users who are not in one or this group will receive the default GAL. The name of the GAL is not listed here!

Figure 11: GAL in OWA

You can view all address lists in Active Directory using Outlook Web Access via a Microsoft article without the permissions set on the address list. To avoid users being able to see and browse all the GALs created in your Exchange organization, you can change the value of the msExchQueryBaseDN attribute on user properties with AdsiEdit from the default value to. A distinguished name of the custom GAL that you want users to see in OWA, as shown in Figure 12.
