Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-outlook-calendar list my events for tomorrow"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

API Permissions → Add Calendars.ReadWrite and Tasks.ReadWrite (both delegated)
Copy the Application (client) ID

# Edit .env: paste your OUTLOOK_CLIENT_ID
pip install -e .python3 src/server.pyOn first run, the server prints a device code URL and code to stderr.
Open the URL, enter the code, sign in with your Microsoft account.
The token is cached at ~/.cache/mcp-outlook-calendar/token_cache.bin and auto-refreshes.
