Request-based chat - Start and import chat as guest user from classic view
You can start a Microsoft Teams chat with an external organization user and import chat after you are invited to their chat.
The following configuration must be complete for a guest user from an allowed-domain to initiate or import chat.
- Enable chat access to a guest user
- Configure external collaboration for a guest user
- Add a guest user to the Microsoft Entra ID
For more information, see Enable chat access for guest users for self-configured app, Enable chat access for a guest user for pre-published app, and Guest access in Microsoft Teams.
As a guest user, you can import chat only if you are present in the allowed-domain but you can initiate a chat. A tag with the label External appears by your name to indicate that you are a guest user and not present in the allowed-domain. For more information, see Add or invite people outside your Teams org to a chat.
