Default Address Book Policy for new users in Exchange Online

Question

Hello everyone,

I have a question about the AdressBookPolicy in Exchange Online:
Is it now possible to specify an ABP for all new users in the Tenant or in a MailboxPlan?
In a post from Nov 2018 the statement was that it is not possible.

Per Powershell I saw that in the MailboxPlan there is the field "AddressBookPolicy", but how to populate it and is it meant for that?

Greetings
David

Answer 1

Still need to assign per mailbox:

That mailbox plan switch may be used one day? There is alot they dont seem to use.
But the ones you can modify are listed here:

Hi @David Jacobs

Agree with Andy, the Address Book Policy determines what address lists a user sees in their Outlook or OWA. When a new mailbox is created, the “AddressBookPolicy” attribute is empty. So we still need to assign the policy for newly created users.

And AddressBookPolicy parameter is not supported in MailboxPlan currently.

Thank you very much for your answers.

I hoped that Microsoft had become active here. Well, maybe something will happen here in the future.
