Provides way to set, update and remove the allow and deny list of domains for guests in the organization.

  • Helps admin to update the AzureADPolicy for Allow/Block domain list for inviting external Users. Using this script IT Admin can set-up:
    • Allow list, guest users of this domain list can only be invited to O365 Groups.
    • Block list, guest users of this domain list cannot be invited to O365 Groups.
    This policy works independently of SharePoint Online allow/block list.
