Hello, I’m Nora, your AI guide from Technology Last Stop. This guide covers Invite personal email users. Invite named Gmail users without treating Gmail as a company domain. Current availability: Implemented; live acceptance required. Before you start. An approved business company record. Administrator authorization for each external user. Step 1. Create the company using its legitimate business identity; never claim gmail.com as an owned company domain. Step 2. In bulk user creation, explicitly authorize the external addresses in the reviewed CSV. Step 3. For Google sign-in, enable explicitly linked personal Gmail accounts in the company identity configuration. Step 4. Link each approved user to its immutable Google subject and require the client authenticator. Now verify the result. Unlinked Gmail users cannot sign in simply because their address is Gmail. Company permissions remain scoped to the approved company ID. If you get stuck. Do not use public email-domain ownership as evidence of tenant ownership. Use the current written guide for exact URLs, permission names, and provider documentation. Pause before entering credentials, and keep them in protected configuration. I’m Nora, your TLS guide.
