Look Up Outlook Contacts with Claude on Windows — No Azure AD
Connect Claude, Cursor, VS Code or ChatGPT to your Outlook address book on Windows. Search by name, pull emails and phone numbers, and resolve people before sending an email or booking a meeting. No Azure AD, no Graph API.
LMCP executes local tools on your device. Cloud AI providers and connected services can receive requested data; their terms apply.
What You Can Do
- List contacts — pull the full address book from your Outlook profile
- Search contacts — find people by name, email fragment, or company
- Get a contact’s details — look up one person’s emails, phone numbers, job title and company
These read the same address book Outlook itself shows you — local contacts and any directory entries your profile has cached, not a separate database.
How to Install
Download LMCP for Windows and install it:
- Run the downloaded
LMCP-Setup.exefrom your Downloads folder - Follow the installer — no admin rights needed, it installs to your user folder
- LMCP starts automatically and appears in your system tray
Takes about 30 seconds. Your AI clients are configured automatically.
Make sure classic desktop Outlook is installed, has a mail profile configured, and has been opened at least once.
Then restart your AI client:
- Claude Desktop — quit completely and reopen
- Cursor — restart the editor
- VS Code — reload the window (Ctrl+Shift+P → “Reload Window”)
- ChatGPT / Windsurf — restart the application
Example Prompts
- “Find Sarah’s email at Northwind Traders” — searches by name and company
- “What’s Mike Chen’s phone number?” — pulls the full contact card
- “List everyone at Contoso in my contacts” — searches by company fragment
- “Look up Priya’s email and draft a reply to her last message” — resolves the person, then hands off to Outlook mail
Why This Skips Azure AD and Graph API
The official way to read a Microsoft 365 directory is the Graph API — an app registration in Microsoft Entra ID, OAuth scopes, and usually tenant admin approval before anything can query People or Contacts. LMCP talks to Outlook through COM automation instead, the same interface Outlook add-ins use. If Outlook shows you the contact, your AI can look it up the same way — no tenant, no consent screen.
Real-World Workflows
Resolve a name before sending
Look up Priya Sharma’s email in my contacts, then draft a reply to her last message about the vendor contract.
Your AI resolves the name to a real address before it touches Outlook mail — no copying an email by hand.
Meeting invite from a name
Find the contact card for James at Fabrikam, then check my calendar and schedule a 30-minute call with him next Tuesday afternoon.
Contacts feeds straight into your Outlook calendar — the AI resolves who “James at Fabrikam” is before it books anything.
LMCP also connects your AI assistant to Outlook email, Outlook Calendar, Microsoft Teams and OneDrive on Windows. See the full list of guides or learn more at local-mcp.com.
Limitations
- Requires classic desktop Outlook — the new Outlook app (Microsoft.OutlookForWindows) does not register the COM interface LMCP uses.
- Reads what Outlook itself shows — if a contact is not in your Outlook address book, LMCP cannot see it either.
- One mailbox profile at a time — if you use multiple Outlook profiles, LMCP works with the one currently open.
Frequently Asked Questions
Can Claude search my Outlook contacts without Azure AD or Graph API?
Yes. LMCP talks to classic desktop Outlook directly through COM automation — no Azure AD app registration, no OAuth tokens, no Graph API key.
Does this include contacts from my company directory, or just personal contacts?
It reads whatever Outlook itself has — personal contacts and any directory entries your profile has already cached (for example, people you have emailed before). It is not a live query against your organization’s full directory.
Does it work with the new Outlook app?
No — the new Outlook app (Microsoft.OutlookForWindows) does not expose the COM interface LMCP relies on. You need classic desktop Outlook.
Do I need a Microsoft 365 subscription or API keys?
No. LMCP uses the Outlook already installed and signed in on your PC — no subscription-gated API, no keys, no admin approval.
