Before you begin, confirm that your Azure admin has granted org-wide Microsoft Graph API access and permissions. See [App ID for Microsoft Graph Authentication](https://help.salesforce.com/s/articleView?id=sales.activity_capture_graph_api.htm&release=264.0.0&type=5). The admin setting up the connection from Microsoft is required to be assigned the DirectoryRole of a Global Admin, Cloud Application Admin, or Application Admin.

1. From Setup, in the Quick Find box, enter Einstein Activity Capture, and then select **Settings**. If it’s your first time setting up Einstein Activity Capture, the setup flow guides you through the steps. If you already set up Einstein Activity Capture and want to change the authentication method, reset Einstein Activity Capture.
2. Select **Microsoft 365** as the email and calendar app.
3. Select **Application-Level OAuth 2.0** as the authentication method.
4. Review the server URL that we’ll redirect you to when you log in to your Microsoft Office 365 account.
5. Click **Log In** and enter your company’s Microsoft Office 365 account credentials. Then, accept Salesforce access to Microsoft Office 365.
    
    When you’re done, you return to the Einstein Activity Capture setup flow and Salesforce auto-populates the tenant ID field.
6. Optionally, test the connection between Salesforce and Microsoft Office 365.
7. Follow the remaining steps in Einstein Activity Capture setup, which includes [creating a configuration and adding users to it](https://help.salesforce.com/s/articleView?id=sales.aac_setup_create_configuration.htm&release=264.0.0&type=5 "Configurations determine which data gets captured and how it flows between Salesforce and your connected account. You create one configuration during the initial setup and you can add more to customize data capture and sync behavior for specific users or profiles. By default, Einstein Activity Capture syncs events and contacts bi-directionally, though you can edit these settings at any time.").
    
    After setup is complete, Einstein Activity Capture automatically syncs data for the configured users.
