OWA Exchange MCP Server
Connects to any Microsoft Exchange or OWA deployment and exposes 30 tools across email, calendar, directory, folders, availability, and meeting analytics. You can read and send mail, create and respond to meetings, search Active Directory, find common free time slots across attendees, and pull meeting statistics. Handles browser-based 2FA login with headless automation, then encrypts session cookies at rest with AES-256. Works with on-premise or hosted Exchange servers. Reach for this when you need an LLM agent to interact with corporate Exchange infrastructure, especially in environments that still run their own mail servers instead of Office 365.
