## Quick Start

**IMPORTANT: Choose the right action!**
- User says "draft" or "prepare" → Use `OUTLOOK_CREATE_DRAFT` (saves to Drafts folder)
- User says "send" → Use `OUTLOOK_SEND_EMAIL` (sends immediately)

```bash
# SEND EMAIL (sends immediately - always include agent tag)
curl -s "https://backend.composio.dev/api/v3/tools/execute/OUTLOOK_SEND_EMAIL" \
