# Send an Outlook.com email

Automatically send an Outlook.com email on outlook.live.com. Send an email from Outlook.com (outlook.live.com) to a recipient, with a subject and body. Confirms the message actually left by finding it in Sent Items, rather than assuming the Send click worked.

## Run it

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

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

## Input

- `to` (string, required): Recipient email address, e.g. someone@example.com
- `body` (string, optional): Plain text body of the message. Give a subject, a body, or both — a message with neither cannot be identified in Sent Items afterwards, so the send could not be confirmed.
- `subject` (string, optional): Subject line. Give a subject, a body, or both — a message with neither cannot be identified in Sent Items afterwards, so the send could not be confirmed.
- `sentFolder` (string, optional): Name of the sent-mail folder as shown in your folder list, used to confirm the message left. Override this if your mailbox is not in English.

## Output

- `to` (string, required)
- `sent` (boolean, required): True only when the message was found in Sent Items afterwards. Never inferred from the Send click.
- `subject` (string | null, required)
- `body` (string | null, optional)
- `sentId` (string | null, optional): Row id of the message in Sent Items.
- `composed` (object | null, optional): What the composer held just before sending. Separates a fill failure from a send failure.
- `unsentReason` (string | null, optional)
- `confirmationDialog` (boolean, optional): Whether Outlook asked for confirmation before sending, which it does when the message has no subject. It is confirmed automatically; the message is sent either way.
