Claude Code How to use Microsoft Outlook Mail with Claude Code
You want Microsoft Outlook Mail inside Claude Code so it can clear a backlogged inbox, draft replies across personal and shared mailboxes, find messages waiting on other people, and send approved follow-up email — without you copy-pasting between tabs. Here is the whole setup, once.
Create your Microsoft Outlook Mail gateway
The gateway is the thing Claude Code connects to, and it is where you decide which Microsoft Outlook Mail 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 Mail tools
In the dashboard, create a gateway and pick the Microsoft Outlook Mail 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>
Connect the gateway to Claude Code
-
Add the gateway as a remote HTTP MCP server
claude mcp add arcade --transport http "<YOUR_ARCADE_GATEWAY_URL>"
-
Verify it was added

Try these Outlook prompts
Claude Code can now act on your Microsoft Outlook Mail account. Click a prompt to copy it.
Control whether an agent can read, draft, send, or move mail, and limit access to a user's or shared mailbox. Pair it with Contextual Access policies so sending messages or moving a selection of emails can require approval.
