Automatically apply Addressbook policy

Is there a way to automatically apply a specific Exchange Online Addressbook policy (ABP) when new mailboxes are created? (Without running scheduled powershell)

    Hi shnlnryn​ ,

    No, Exchange Online does not currently support automatically applying a specific Address Book Policy (ABP) at mailbox creation natively.
    You must use automation (PowerShell, Graph API, provisioning workflow, etc.) Microsoft 365 does not have a built-in policy assignment trigger.

    You can use Graph API and Dynamic Group Membership, but honestly, scheduled PowerShell script is easier to manage and to create.

    shnlnryn Sadly there doesnt seem to be a way to change the default Address book policy. 
    My best recommendendation would be too set up a powershell script that automatically changes the Address Book policy of the users on a schedule
