Build ETL pipelines based on Outlook data in the Pentaho Data Integration tool.

The CData API Driver for JDBC enables access to live data from data pipelines. Pentaho Data Integration is an Extraction, Transformation, and Loading (ETL) engine that data, cleanses the data, and stores data using a uniform format that is accessible.This article shows how to connect to Outlook data as a JDBC data source and build jobs and transformations based on Outlook data in Pentaho Data Integration.

Configure to Outlook Connectivity

Using OAuth Authentication

Microsoft Graph API uses OAuth 2.0 for authentication. You must register an application in the Microsoft Azure Portal to obtain OAuth credentials (Client ID and Client Secret).

Obtaining OAuth Credentials

  1. Log in to the Azure Portal.
  2. Navigate to Azure Active Directory > App registrations.
  3. Click New registration to create a new application.
  4. Enter an application name and select the appropriate account types.
  5. Set the Redirect URI to your application's callback URL (e.g., http://localhost:33333 for desktop apps).
  6. Click Register to create the application.
  7. On the application overview page, copy the Application (client) ID - this is your OAuthClientId.
  8. Navigate to Certificates & secrets and create a new client secret.
  9. Copy the client secret value - this is your OAuthClientSecret.
  10. Navigate to API permissions and add the required Microsoft Graph API permissions:
    • Mail.Read - For accessing email messages
    • Contacts.Read - For accessing contacts
    • Calendars.Read - For accessing calendar events
    • Tasks.Read - For accessing To Do tasks
    • offline_access - For obtaining refresh tokens
  11. Click Grant admin consent to grant these permissions.

Connecting with OAuth

After setting the following connection properties, you are ready to connect:

  • AuthScheme: Set this to OAuth.
  • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Outlook will automatically walk through the OAuth process in order to obtain the access token.
  • OAuthClientId: Set this to the Application (client) ID from Azure Portal.
  • OAuthClientSecret: Set this to the client secret value from Azure Portal.
  • TenantId: Set this to your Azure AD tenant identifier (GUID or domain name like 'contoso.onmicrosoft.com').
  • CallbackURL: Set this to the Redirect URI you specified in your app registration (e.g., http://localhost:33333 for desktop apps).

Example connection string

Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Outlook JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.api.jar

Fill in the connection properties and copy the connection string to the clipboard.

When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Below is a typical JDBC URL:

jdbc:api:Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;

Save your connection string for use in Pentaho Data Integration.

Connect to Outlook from Pentaho DI

Open Pentaho Data Integration and select "Database Connection" to configure a connection to the CData API Driver for JDBC

  1. Click "General"
  2. Set Connection name (e.g. Outlook Connection)
  3. Set Connection type to "Generic database"
  4. Set Access to "Native (JDBC)"
  5. Set Custom connection URL to your Outlook connection string (e.g.
    jdbc:api:Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;
  6. Set Custom driver class name to "cdata.jdbc.api.APIDriver"
  7. Test the connection and click "OK" to save.

Create a Data Pipeline for Outlook

Once the connection to Outlook is configured using the CData JDBC Driver, you are ready to create a new transformation or job.

  1. Click "File" >> "New" >> "Transformation/job"
  2. Drag a "Table input" object into the workflow panel and select your Outlook connection.
  3. Click "Get SQL select statement" and use the Database Explorer to view the available tables and views.
  4. Select a table and optionally preview the data for verification.

At this point, you can continue your transformation or jb by selecting a suitable destination and adding any transformations to modify, filter, or otherwise alter the data during replication.
