Connect Claude to Microsoft Outlook
Give your AI assistant full access to Outlook — emails, calendar, contacts. All local, no API keys, no Graph API.
Platform: Windows 10+
Requirements: Microsoft Outlook desktop app installed, LMCP installed
What You Can Do
Once LMCP is installed, your AI assistant can:
- List emails — "Show my last 10 emails" or "List emails in my Sent Items"
- Read full email — "Read that email from John about the proposal"
- Search — "Find emails about the Q1 budget"
- Send — "Send an email to [email protected] with the meeting notes"
- Reply / Reply All — "Reply to that email saying I'll be there"
- Forward — "Forward that to my manager"
- Move — "Move all newsletters to the Archive folder"
- Flag — "Flag that email as important"
- Save attachments — "Save the PDF attachment to my Downloads"
Calendar
- List events — "What meetings do I have this week?"
- Create events — "Schedule a call with the team tomorrow at 3pm"
- Delete events — "Cancel the meeting on Friday"
- List calendars — "What calendar folders do I have?"
Contacts
- List contacts — "Show my contacts"
- Search — "Find contact info for John Smith"
- Get details — "What's Sarah's phone number?"
How It Works
LMCP connects to Outlook using COM automation — the same technology that macros and scripts use. This means:
- No Microsoft Graph API setup
- No OAuth tokens or app registrations
- No data sent to the cloud
- Works with any Outlook account (Exchange, Microsoft 365, IMAP, POP3)
The AI sends a command to LMCP, LMCP talks to Outlook via COM, and returns the result. Everything happens on your PC.
Setup
If you haven't installed LMCP yet, follow the Windows setup guide.
Outlook tools work automatically once LMCP is installed — no extra configuration needed. Just make sure Outlook is installed and has at least one account configured.
Tips
- Outlook must be installed — the web version (outlook.com) is not supported. You need the desktop app.
- First launch — the first Outlook tool call may take a few seconds as COM initializes. Subsequent calls are fast.
- Multiple accounts — LMCP accesses the default Outlook profile. If you have multiple accounts, they're all accessible.
