Connect AI agents to Microsoft 365

Scalekit connector
Open markdown

The Microsoft 365 connector lets your AI agent act in each user's Microsoft 365 account. Each user signs in to Microsoft 365 once, and Scalekit stores and refreshes their tokens, so your agent never handles credentials. It comes with 317 tools.

What you can do

  • Read and send email: list, search, send, reply to, forward, and move Outlook messages, including shared mailboxes
  • Manage calendars: create, update, and respond to Outlook events, check free/busy time, and find meeting times
  • Work in Teams: send channel and chat messages, reply to threads, create teams and channels, and schedule online meetings

  • Update Excel workbooks: read and write ranges, manage tables and worksheets, and create charts
  • Manage tasks, contacts, and notes: create and update To Do tasks and Outlook contacts, and create OneNote pages

Setup

  1. Install the SDK

    Terminal window
    npm install @scalekit-sdk/node dotenv

  2. Set your credentials

    Add your Scalekit credentials to your .env file. Find values in app.scalekit.com > Developers > API Credentials.

    .env
    SCALEKIT_ENVIRONMENT_URL=<your-environment-url>
    SCALEKIT_CLIENT_ID=<your-client-id>
    SCALEKIT_CLIENT_SECRET=<your-client-secret>

  3. Create the Microsoft 365 connection

    In AgentKit > Connections, create a Microsoft 365 connection. The name you give it is the connection_name your code passes. See Configure connections.

    Scalekit credentials are available for Microsoft 365, so you don't need to register an OAuth app. To show your own app on the consent screen, use your own credentials instead.

    Use your own OAuth app

    Register your Scalekit environment with the Microsoft 365 connector so Scalekit handles the authentication flow and token lifecycle for you. The connection name you create will be used to identify and invoke the connection programmatically. Then complete the configuration in your application as follows:

    1. Create the Microsoft 365 connection in Scalekit

      • In Scalekit dashboard, go to AgentKit > Connections > Create Connection. Search for Microsoft 365 and click Create.

      • In the Configure Microsoft 365 Connection dialog, copy the Redirect URI. You will need this when registering your app in Azure.

    2. Register an application in Azure

      • Sign into portal.azure.com and go to Microsoft Entra ID → App registrations.

      • Click New registration. Enter a name for your app (for example, “Scalekit Microsoft 365 Connector”).

      • Under Supported account types, select Accounts in any organizational directory (Any Microsoft Entra ID tenant - Multitenant) and personal Microsoft accounts.

      • Under Redirect URI, select Web and paste the redirect URI you copied from the Scalekit dashboard. Click Register.

    3. Get your client credentials

      • From the app’s Overview page, copy the Application (client) ID.

      • Go to Certificates & secrets in the left sidebar, then click + New client secret.

      • Enter a description (for example, “Secret for Scalekit Agent Actions”), set an expiry period, and click Add. Copy the secret Value immediately — it is only shown once.

    4. Add credentials in Scalekit

      • In Scalekit dashboard, go to AgentKit > Connections and open the Microsoft 365 connection you created.

      • Enter your credentials:

        • Client ID — the Application (client) ID from the Azure app overview
        • Client Secret — the secret value from Certificates & secrets
        • Scopes — select the permissions your app needs (for example, Calendars.Read, Calendars.ReadWrite, Mail.Read, Mail.ReadWrite, Mail.Send, Contacts.Read, Contacts.ReadWrite, User.Read, offline_access). See Microsoft Graph permissions reference for the full list.

      • Click Save.

  4. Authorize a user and make your first call

    quickstart.mts
    import { ScalekitClient } from '@scalekit-sdk/node'
    import 'dotenv/config'
    import { createInterface } from 'node:readline/promises'
    

    const scalekit = new ScalekitClient(
      process.env.SCALEKIT_ENVIRONMENT_URL,
      process.env.SCALEKIT_CLIENT_ID,
      process.env.SCALEKIT_CLIENT_SECRET,
    )
    const actions = scalekit.actions
    

    const connector = 'microsoft365'
    const identifier = 'user_123'
    

    // Generate an authorization link for the user
    const { link } = await actions.getAuthorizationLink({ connectionName: connector, identifier })
    console.log('Authorize Microsoft 365:', link)
    const rl = createInterface({ input: process.stdin, output: process.stdout })
    await rl.question('Press Enter after authorizing...')
    rl.close()
    

    // Make your first call
    const result = await actions.executeTool({
      connector,
      identifier,
      toolName: 'microsoft365_onedrive_get_drive',
      toolInput: {},
    })
    console.log(result)
    Terminal window
    npx tsx quickstart.mts

    Each user signs in once. See Authorize a user for the full flow and statuses.
