Claude Code How to use Microsoft Outlook Calendar with Claude Code
You want Microsoft Outlook Calendar inside Claude Code so it can coordinate meetings across calendars, keep event details up to date, triage incoming invitations, and cancel or reschedule a meeting safely — without you copy-pasting between tabs. Here is the whole setup, once.
Create your Microsoft Outlook Calendar gateway
The gateway is the thing Claude Code connects to, and it is where you decide which Microsoft Outlook Calendar tools an agent may use. You create it once and every client reuses it.
-
Create an Arcade account
Sign up and open the dashboard. The free tier is enough to follow this through.
-
Create an MCP Gateway and select your Microsoft Outlook Calendar tools
In the dashboard, create a gateway and pick the Microsoft Outlook Calendar tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.
-
Copy your gateway URL
Every client below needs it.
https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>
