What is the Microsoft Outlook Mail MCP Server?

The Microsoft Outlook Mail MCP server gives AI agents structured, permission-aware access to Microsoft Outlook Mail through the Model Context Protocol. With 20 pre-built actions, agents can read, create, and update Microsoft Outlook Mail data on behalf of authorized users.

Willow ships the Microsoft Outlook Mail MCP server as part of an enterprise control plane. Every call runs behind SSO (Okta, Azure AD), enforces RBAC and least-privilege at runtime, writes to a full audit trail, and integrates with Splunk and Loki for SIEM visibility. Connect from Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code, n8n, or any custom agent. Install once, distribute org-wide, and see exactly how Microsoft Outlook Mail is being used by every AI agent in your stack.

Enterprise Governance for Microsoft Outlook Mail

Willow adds the layer Microsoft Outlook Mail and every other SaaS doesn't ship out of the box: every call runs behind SSO (Okta, Azure AD), enforces RBAC and least-privilege at runtime, writes to full audit logs, and detects shadow AI usage across your stack. One MCP gateway. Any agent. Every tool.

Microsoft Outlook Mail MCP Server FAQ

What is the Microsoft Outlook Mail MCP server?

The Microsoft Outlook Mail MCP server is a Model Context Protocol implementation that lets AI agents like Claude, Cursor, and ChatGPT read and write Microsoft Outlook Mail data through a standardized interface. Willow hosts and governs this server so enterprises can roll it out without a security review backlog.

How is Willow's Microsoft Outlook Mail MCP server different from the official one?

The official Microsoft Outlook Mail MCP server is scoped to a single user's account and does not include enterprise governance. Willow's version adds SSO, RBAC, audit logging, shadow AI detection, and centralized control over which actions agents can take across the entire org.

Which AI clients work with the Microsoft Outlook Mail MCP server?

Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code with MCP support, n8n, and any custom agent built with OpenAI Agents SDK, LangChain, Vercel AI SDK, or Anthropic SDK.

Is the Microsoft Outlook Mail MCP server secure? How does Willow handle authentication?

Every call runs behind your existing SSO (Okta, Azure AD). Per-user OAuth scopes the agent to exactly what that user can do in Microsoft Outlook Mail, nothing more. No credentials reach the LLM. Every action writes to an audit trail.

Can I limit which Microsoft Outlook Mail actions agents can take?

Yes. Willow lets you scope agents to specific actions, specific projects, or specific environments. Toggle actions on or off in the dashboard, or enforce policy via infrastructure-as-code through GitHub.

How do I detect shadow Microsoft Outlook Mail MCP servers in my org?

Willow's browser extension and discovery service surface unmanaged MCP servers, skills, and AI agents across the org. If a developer installed an unapproved Microsoft Outlook Mail MCP locally, you'll see it.

What does the Microsoft Outlook Mail MCP server cost?

Pricing depends on org size and deployment model (SaaS, dedicated cloud, self-host). See withwillow.ai/pricing or contact sales for a quote.

How do I install the Microsoft Outlook Mail MCP server with Willow?

Install via the Willow Connect Panel in one click, or paste the JSON snippet above into your Claude Desktop, Cursor, or Claude Code config. SSO and RBAC inherit from your existing Willow setup.
