Limit visibility of group messages
As a G Suite administrator, you can control who sees messages sent to a group in your domain. You can set visibility options so only members of a group can:
- See members of the group
- Join the group
- Post to the group
- Read and search the message archive
You can set the visibility level when you create groups using the Admin console, Google Groups, or APIs. You can also audit existing groups to find groups that let non-members view messages and change their visibility level.
Set visibility of groups in Admin console
As a G Suite administrator, you can set the visibility level when you create a group in the Google Admin console:
- Create a group in the Admin console.
- From the Access Level drop-down list, choose the visibility level.
Set visibility in Google Groups
As a G Suite administrator, you can set the visibility options for existing groups in Google Groups:
From the Admin console Home page, go to Groups.
To see Groups, you might have to click More controls at the bottom.
- Point to a group, and click Edit settings.
- At the bottom of the page, click advanced settings. You’re taken to the group's permissions page in your Groups for Business service.
- Select the settings you want to change under Basic permissions and Access permissions in the menu on the left.
Set visibility with APIs
When you create a group using the Directory API, the default for the View Topics option is set to All members of the group.
Sample scripts are available on GitHub that you can customize for your own use.
