This feature is only available to organizations on the Enterprise plan.
Organization admins can control whether members are allowed to add guests to spaces and threads, and limit which domains guests can be added from.
Please note that this will not remove any guests who have already been added as guests in the organization. Admins can view and remove any guests in the organization from the Guests section of the Members tab.
To manage how members are able to add guests to spaces and threads:
- Go to organization Settings
- Go to the General settings tab
- Manage your preferences under Inviting new members and adding guests
