# Reply all

> Reply to all recipients selected by Outlook.

`replyAll` immediately replies using Outlook's reply-all recipient rules.

```ts automations/reply-all-outlook.automation.ts theme={null}
import { automation } from "automate.ax"
import { replyAll } from "automate.ax/outlook"

export default automation("Reply all in Outlook", () => {
  replyAll({
    messageId: "AAMkAGI2...",
    bodyType: "html",
    body: "<p>Confirmed for everyone.</p>",
  })
})
```

Required `messageId` and `body` identify the source and content. `bodyType`
defaults to `text`; optional `account` selects the binding. Returns
`Signal<void>`. This can send to every recipient selected by Outlook, so use
`reply` when only the sender should receive the response.
