Hi,@Steven Paredes
Thanks for posting your question in the Microsoft Q&A forum.
It sounds like you're working with Microsoft Exchange and want to configure Address Book Policies (ABPs) to control which users see which Global Address List (GAL).
I checked the official documentation and found that you can only create, modify, delete, and update a GAL using Exchange Online PowerShell.
According to the documentation, you can only use Exchange Online PowerShell to create ABP, so your requirement cannot be met.
If my answer is helpful to you, please mark it as the answer so that other users can refer to it. Thank you for your support and understanding.
