What is Outlook CLI?
The Outlook CLI skill provides a comprehensive bridge between your AI agent and the Microsoft 365 ecosystem. By utilizing the Microsoft Graph API, this tool allows for seamless management of Outlook, Live.com, and Hotmail accounts. It is designed to be a core component of your Openclaw Skills library, enabling developers to build sophisticated automation workflows that involve reading, sending, and searching emails, as well as managing complex calendar schedules.
This skill is built with security in mind, employing OAuth 2.0 device code flows and local token encryption. Whether you are running an agent on a local machine or a headless server, this skill provides the necessary interface to interact with Microsoft communications without requiring a GUI.
Outlook CLI Use Cases
- Automated inbox monitoring for specific triggers like invoices or project updates.
- Seamless scheduling of team meetings and project reviews directly through the agent.
- Sending multi-recipient emails with CC support and file-based message bodies.
- Headless email management on remote servers where browser access is restricted.
- Advanced searching of historical email data using specific Microsoft Graph operators.
How Outlook CLI Works
- Configuration: The user provides Azure AD application credentials to establish a verified connection with Microsoft services.
- Authentication: The skill uses the OAuth 2.0 device code flow to obtain secure access tokens, allowing for authentication on machines without a browser.
- Token Persistence: Tokens are stored locally with restrictive file permissions to ensure security while enabling automatic refreshes for long-term use.
- API Execution: Agent commands are converted into authenticated HTTPS requests to the Microsoft Graph API endpoints.
- Output Processing: The API results are parsed and presented in a clean, developer-friendly format for the agent to interpret or display.
Outlook CLI Setup
To integrate this into your collection of Openclaw Skills, follow these steps:
- Register an app in the Azure Portal (portal.azure.com) under App registrations.
- Set the platform to Public client/native and enable http://localhost:8080/callback as a redirect URI.
- Grant the following API permissions: Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, and offline_access.
- Ensure Python 3 and the requests library are installed on your system.
- Run the configuration command:
outlook configure
- Perform the initial authentication using the device code flow:
outlook auth --device-code
- Secure your credential storage immediately:
chmod 600 ~/.config/outlook-cli/token.json
