    Please find below steps to create a customize GAL in your environment.

     

    Create New Address Book Policy

    Before Creating a policy, we have to create:
    AddressList
    GlobalAddressList
    OfflineAddressBook
    RoomList

     

    New-GlobalAddressList -Name “GAL IT” -IncludedRecipients MailboxUsers -ConditionalDepartment IT

     

    NEW-ADDRESSLIST -NAME “IT” -RECIPIENTFILTER {((RECIPIENTTYPE -EQ ‘USERMAILBOX’))} -RECIPIENTCONTAINER IT

     

    NEW-OFFLINEADDRESSBOOK -NAME “IT OAB” -ADDRESSLISTS “IT”

     

    New-AddressBookPolicy -Name “IT Team” -AddressLists “IT” -OfflineAddressBook “IT OAB” -GlobalAddressList “GAL IT” -RoomList “IT_confRoomList”

     

    Set-Mailbox -Identity "Test1" -AddressBookPolicy ‘IT Team’

     

    Regards,

    MD

ABPs are assigned to users indeed, so you will have to expand the membership of the group and assign the ABP to each user. Rinse and repeat when users are added/removed from the group as needed.
