OpenClaw Outlook Add-in Connects Local Agent to Email Sidebar

Direct Integration with Local OpenClaw Agent

A developer has released an Outlook add-in that connects directly to your local OpenClaw Gateway via WebSocket. Unlike basic AI email helpers, this tool provides access to your entire OpenClaw agent with all configured tools, skills, and automations from within Outlook's sidebar.

Core Functionality

The add-in reads the currently selected email's subject, sender, and body content, passing this as context to your OpenClaw agent. You can then chat with your agent in the sidebar interface, maintaining the same capabilities and tools you normally use.

Key Features from Source

• One-click draft reply generation that opens Outlook's native compose window for review
• Per-email chat sessions that persist when switching between emails
• Light/dark mode auto-detection based on Outlook's theme
• Pinned sidebar option and automatic WebSocket reconnection
• Works with Outlook Desktop (Classic), Outlook Web (OWA), and Microsoft 365

Practical Applications

Since the add-in connects to your full OpenClaw agent, you can perform any actions your agent is configured for directly from Outlook. The source mentions examples including creating calendar events, querying a Redmine tracker, looking up contacts, and triggering automations.

Technical Implementation

The add-in is built with Office.js and vanilla JavaScript, using a webpack development server with a WebSocket Secure (WSS) proxy to the local OpenClaw Gateway. The architecture keeps everything local—no cloud services or third-party dependencies are required, with all communication running through localhost.
