MCP server for Outlook email, calendar, and contacts
Outlook Assistant
MCP server for Outlook email, calendar, and contacts — let your AI assistant manage your inbox directly from the conversation.
Outlook Assistant connects AI assistants to your Microsoft Outlook account through the Model Context Protocol. Ask your AI assistant to search your inbox, send emails, schedule meetings, manage contacts, and configure mailbox settings — without leaving the conversation. Works with Claude, Cursor, Windsurf, and any MCP-compatible client.
Works with personal Outlook.com and work/school Microsoft 365 accounts.
Search inbox → read & summarise → draft a reply — all from the conversation
What you can do
- 📨 Search and read emails — find messages by sender, subject, date, or keywords; read full threads with conversation grouping; batch flag, move, export, or categorise multiple emails at once
- 🛡️ Send emails with safety controls — dry-run preview, pre-send mail tips (out-of-office, mailbox full, delivery restrictions), session rate limiting, and recipient allowlist to prevent mistakes
- 📅 Manage your calendar — view upcoming events, schedule meetings with attendees, decline or cancel invitations
- 📦 Export emails — save to Markdown, EML, MBOX, JSON, or HTML for archiving, analysis, or migration; export search results or entire threads in one call
- 🔍 Investigate email headers — check DKIM, SPF, and DMARC authentication; trace delivery chains; analyse spam scores — useful for phishing investigation and compliance
- 🗂️ Organise your inbox — create folders, set up inbox rules, colour-code with categories, manage Focused Inbox — all work together for complete inbox automation
- 🔄 Track inbox changes — delta sync detects new, modified, and deleted emails since your last check, with tokens for incremental polling
- 👥 Manage contacts — search your contact book and organisational directory, create and update contact records
- ⚙️ Configure settings — set out-of-office auto-replies, working hours, and time zone
- 📬 Access shared mailboxes — read team inboxes and service accounts (Microsoft 365)
- 🏢 Find meeting rooms — search by building, floor, capacity, AV equipment, and wheelchair accessibility (Microsoft 365)
