Get started: Create a simple mailing list
(Optional) Turn off Google Groups in additional Google services
The Google Groups additional service is separate from the Groups for Business core service.
Whereas the Groups for Business core service controls groups in your organization, the Groups additional service controls access to groups outside your organization. You can turn this additional service ON or OFF in the Admin console. By default, the service is ON:
ON—Users in your organization can access groups outside your organization from their organization accounts (groups.google.com/forum).
OFF—Users in your organization can’t access external groups from their organization accounts.
To turn off the Google Groups additional service:
From the Admin console Home page, go to AppsAdditional Google services.
- Scroll down to Google Groups and click the service name to open its settings page.
Under ON for everyone, select OFF for everyone, then click Save.
