Setup Guide

Requirements

✓Microsoft 365 Business/Enterprise subscription or Exchange Online
✓Azure AD app registration (admin consent required for org-wide features)
✓OpenClaw running on a server or Mac
✓IT admin approval for app registration (enterprise environments)

Register an Azure AD application

In Azure Portal, go to Azure Active Directory > App registrations > New registration. Name it 'OpenClaw Assistant' and set the redirect URI to http://localhost:8080/callback for desktop apps.

Configure API permissions

Add Microsoft Graph permissions: Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, User.Read. For org-wide features, request admin consent.

Create client credentials

Under Certificates & secrets, create a new client secret. Save the Application (client) ID and secret value securely.

Configure OpenClaw

Add the Microsoft configuration to your OpenClaw config with clientId, clientSecret, and tenantId.

Authenticate

Run the OAuth flow to sign in with your Microsoft 365 account. This grants OpenClaw access to your mailbox and calendar.

Test the connection

Ask your assistant 'What meetings do I have today?' or 'Summarize my unread emails' to verify access.

Configuration Example

microsoft:
  clientId: \"your-azure-app-client-id\"
  clientSecret: \"your-client-secret\"
  tenantId: \"your-tenant-id-or-common\"
  scopes:
    - Mail.ReadWrite
    - Mail.Send
    - Calendars.ReadWrite

Frequently Asked Questions

Do I need IT admin approval?

For personal Microsoft accounts, no. For enterprise Microsoft 365, your IT admin may need to approve the app registration and grant admin consent for organization-wide permissions.

Is this compliant with enterprise security policies?

OpenClaw runs on infrastructure you control. Data doesn't pass through third-party cloud services. The integration uses standard Microsoft Graph API with OAuth 2.0, compatible with most security policies.

Can it access shared mailboxes and calendars?

Yes, with appropriate permissions. Your IT admin can configure delegated access to shared resources through Azure AD.

Does it work with on-premises Exchange?

This integration is optimized for Exchange Online (Microsoft 365). On-premises Exchange requires EWS configuration, which may need additional setup.

Can it send emails on my behalf?

Yes, with Mail.Send permission. You can configure approval requirements for sends or limit to drafts only for review before sending.

What about data residency requirements?

OpenClaw processes data locally on your infrastructure. Your Microsoft 365 data remains in your tenant's configured data residency region.

Can multiple users share one app registration?

Yes, a single Azure AD app registration can authenticate multiple users in your organization. Each user authorizes with their own credentials.

How do I revoke access?

Users can revoke access in their Microsoft account settings under 'Apps and services'. Admins can revoke organization-wide through Azure AD.
