Overview
Users can create tenants via the Manage tenant section of the Azure AD and Entra management site. The Audit log records the formation of a tenant under the categories Directory Management and Create Company. Anyone who creates a tenant also becomes the tenant's Global Administrator. There are no settings or options that the newly established tenant inherits.
