If verified-domain access is required, people can join only with an address from one of the approved domains. The rule controls admission to the organization; it does not change access to users’ private conversations or profiles.

  1. Open Admin and manage the relevant organization.
  2. Choose “Domain” in the left menu.
  3. Add, verify or remove an allowed domain using the available controls.
  4. Confirm the organization’s domain requirement before inviting users.
