# Microsoft Teams

> Read teams and chats, send messages, and react to Microsoft Teams events.

Import Teams actions and triggers from `automate.ax/teams`. They use the shared
Microsoft account connection. Names are convenient configuration values, while
the returned `teamId`, `channelId`, `chatId`, and `messageId` values are stable
references for follow-up work. Action inputs accept plain values or compatible
signals; trigger options are static.

```ts theme={null}
import { automation } from "automate.ax"
import {
  onChannelMessagePosted,
  replyToChannelMessage,
} from "automate.ax/teams"

export default automation("Answer Teams channel posts", () => {
  const message = onChannelMessagePosted({
    team: "Engineering",
    channel: "Help",
  })
  replyToChannelMessage({
    team: message.teamId,
    channel: message.channelId,
    messageId: message.messageId,
    body: "Thanks — we’ll take a look.",
  })
})
```

## Accounts

Leave `account` unset to use the default Microsoft binding, or pass a binding
created with `microsoftAccount`. See [Integration accounts](/concepts/integration-accounts).
Microsoft Teams team APIs require a work or school Microsoft 365 account; some
are unavailable to personal Microsoft accounts.
