# Microsoft Teams

- DMs and channel `@mentions` create chats in Studio with a **TEAMS** badge, and replies route back to Teams without extra wiring.
- Setup: provision an Azure Bot resource (the F0 tier is free), capture the Microsoft App ID, client secret, and tenant ID.
- Assemble a Teams app package with a manifest and icons; Friday's tunnel supplies the messaging endpoint Azure points at (`<tunnel>/platform/teams`).
- Studio's Communicators card stores credentials securely.
- Watch out: the `SingleTenant` vs `MultiTenant` setting must match between Azure and Studio, or outbound replies will fail to authorize.
