# Reply to an Outlook.com email

Automatically reply to an Outlook.com email on outlook.live.com. Reply to one Outlook.com (outlook.live.com) message by its id (from list_emails), optionally replying to all recipients.

## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/outlook.live.com/reply_email`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/outlook.live.com/reply_email
```

## Input

- `id` (string, required): Message id from list_emails (the row's id attribute).
- `body` (string, required): Plain text body of the reply. Required: it is also what identifies the sent reply afterwards.
- `folder` (string, optional): Folder the message is in, as shown in your folder list.
- `replyAll` (boolean, optional): Reply to every recipient rather than just the sender.
- `sentFolder` (string, optional): Sent-mail folder name as shown in your folder list, used to confirm the reply left.

## Output

- `id` (string, required)
- `sent` (boolean, required): True only when the reply was found in the sent folder, with the folder switch itself verified first. Never inferred from the send keystroke.
- `body` (string, optional)
- `composed` (object | null, optional)
- `replyAll` (boolean, optional)
- `sentRowId` (string | null, optional): Row id of the reply in the sent folder. Outlook groups by CONVERSATION, so this is normally the same id as the message replied to — that is expected, not an error.
- `unsentReason` (string | null, optional)
