Microsoft Outlook configuration

This page describes how to set up and configure a third-party configuration before creating the Outlook data store.

Set up authentication and permissions

You need to set up authentication and permissions in Microsoft Entra admin center. This is crucial for allowing the connector to access and synchronize data.

Register Entra app for Microsoft Outlook connector

Before creating the Microsoft Outlook connector in Gemini Enterprise, register a Microsoft Entra application to enable secure access.

To register Gemini Enterprise as an OAuth 2.0 application in Entra, do the following:

  1. Navigate to Microsoft Entra admin center.
  2. In the navigation menu, expand the Entra ID and select App registrations.
  3. On the App registrations page, click New registration.

      2. In the redirect URI field, enter https://vertexaisearch.cloud.google.com/console/oauth/default_oauth.html.
    4. Click Register. Microsoft Entra creates your app and displays the overview page of your app.

  5. In the app navigation menu, click Authentication.

  6. Click Add redirect URI.

Create an OAuth 2.0 configuration

To create a connection using the OAuth 2.0 authentication method, you need to obtain a client ID, client secret, and your Tenant ID from your Microsoft Entra application registration page.

Obtain client ID and client secret

  1. To obtain the client ID and secret for the app, do the following:

    1. On the app page, select Certificates & secrets from the app navigation menu.
    2. Click New client secret.
    3. In the client secret pane, do the following:
      1. In the Description field, enter a description for the secret.
      2. In the Expires list, select an expiry duration.
      3. Click Add.
    4. Copy the secret displayed in the Value column (Client Secret) and the identifier in the Secret ID column (Client ID), and securely store both for later use.

Obtain Tenant ID

Your tenant ID can be found in the Tenant ID box on the overview page in the Microsoft Entra admin center.

Configure Microsoft API permissions

To configure the required API permissions for the app, do the following:

  1. On the app page, select API permissions.

  2. Click Add permissions.

  3. In the Request API permissions page, select Microsoft Graph.
