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.

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
• ✏️ Draft emails for review — create, update, and send drafts; reply and forward as drafts; preview before saving with dry-run mode
• 📅 Manage your calendar — view upcoming events, schedule meetings with attendees, decline or cancel invitations
• 📦 Export emails — save individual messages to Markdown, EML, JSON, or CSV; export full conversation threads to MBOX or HTML; bulk-export search results in one call
• 🔍 Investigate email headers — full raw header access (DKIM, SPF, DMARC, delivery chain, X-Mailer, X-Originating-IP) for phishing investigation and compliance review
• 🗂️ Organise your inbox — create nested folders (addressable by path), 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)

Export Formats

Format support varies by target:

Format	Extension	target=message (single)	target=messages (batch)	target=conversation (thread)
mime / eml	.eml	✅	–	✅
mbox	.mbox	–	–	✅
markdown	.md	✅	✅	✅
json	.json	✅	✅	✅
html	.html	–	–	✅
csv	.csv	✅	✅	✅

Export individual emails, search results, or entire conversation threads — use target=messages with a search query (or the query shortcut) to batch-export without manually collecting IDs.

Account Compatibility

Outlook Assistant works with both personal and work/school Microsoft accounts, but some features behave differently:

Feature	Personal (Outlook.com)	Work/School (Microsoft 365)
Email read, send, search	Full support	Full support
Calendar events	Full support	Full support
Contacts CRUD	Full support	Full support
Inbox rules	Full support	Full support
Folders	Full support	Full support
Free-text query search	Limited — use subject, from, to filters instead	Full KQL support
Categories	Full support	Full support
Mailbox settings	Full support	Full support
Focused Inbox	API works (overrides stored) but mail routing not affected	Full support
Shared mailboxes	Not available	Requires Mail.Read.Shared
Meeting room search	Not available	Requires Place.Read.All + admin consent

Note: On personal accounts, Microsoft's $search API has limited support for free-text queries. Outlook Assistant handles this automatically with progressive search — if your query returns no results, it falls back through OData filters, boolean filters, and recent message listing to find your emails. For the most direct results on personal accounts, use the structured filter parameters (from, subject, to, receivedAfter).

What Makes This Different

• Progressive search — on accounts where Microsoft's $search API is limited, Outlook Assistant automatically falls back through up to 4 search strategies to find your emails. Most Graph API wrappers fail silently; this one adapts.
• Email forensics — raw header access for DKIM, SPF, DMARC, delivery chain, X-Mailer, X-Originating-IP, and spam scores. Returns the full data so you can investigate phishing, audit compliance, or trace delivery issues. (Auto-verdict is on the roadmap; today the data is surfaced and analysed in-conversation.)
• Delta sync — incremental inbox monitoring returns only what changed since your last check, with tokens for continuous polling. Designed for agent workflows that need to watch a mailbox.
• Batch operations — flag, move, export, or categorise multiple emails in a single call. Search-driven export lets you batch-export results without collecting IDs manually.
• Pre-send intelligence — check recipients for out-of-office, full mailbox, delivery restrictions, and moderation status before sending — no other Outlook MCP server offers this.
• Compound automation — rules, categories, folders, and Focused Inbox work together. Set up complete inbox management through your AI assistant in one conversation.
