Generating An Empty Global Address List By Default
Hi CSU_Scott
I think that, for what you're trying to do, the only way is with empty recipientfilters, ( or filter combination with no matches ), in PS. Didn't tested it, but should work. For your reference working with recipient filters: Customizing Address Lists and Address Book Policies in Office 365 | Andrew Morris, MCSE (wordpress.com)
Hope this helps or that finally you achieve your goal.
Have a good day.
We have gone down that path, but what we need is all users to be automatically without any address book without assigning an address book policy. We need to make an empty address book the default policy so we don't have to assign it via a PowerShell script post launch.
Best regards,
Scott
Hi CSU_Scott,
In that case, I guess the only solution for your scenarion are the Information barrier policies.
"If your organization is in single or multi-segment mode, information barriers is no longer based on Exchange Online Address Book Policies (ABPs). Organizations using ABPs will not have any impact to the existing ABPs when enabling information barriers. If there's no ABP defined for users with associated IB segments and policies, an ABP is automatically created with empty address lists for these users. You can change these ABPs as needed. We recommend that your ABPs are consistent with the segments you configure in information barriers. You should try to avoid user visibility differences between your existing ABPs and your new information barriers configuration."

- I like this too. As I read through it, I don't think I can do that. The goal is to not publish the data in the Address Lists by default. They should be allowed to communicate with each other if the users are aware of each other. We want to minimize the publishing of their information while allowing them to communicate as needed.
What about setting all of the existing address lists to Null? Anyone aware of ramifications of doing this?Hi CSU_Scott,
Unfortunately that's something that I never tested.
Let's see if someone else in the Community had to deal with such scenarios. If I can get some time next week I'll test it in a development tenant.
