Analyze Outlook Data with Power Pivot

The ODBC protocol is used by a wide variety of Business Intelligence (BI) and reporting tools to get access to different databases. The CData ODBC Driver for Outlook brings the same power and ease of use to Outlook data. This article uses the driver to import Outlook data into Power Pivot.

Connect to Outlook as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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;

Connect from Power Pivot

Follow the steps below to connect to the DSN in Power Pivot.

1. In Excel, click the Power Pivot Window icon on the Power Pivot tab to open Power Pivot.
2. Launch the Table Import Wizard: Click the Get External Data from Other Data Sources button.
3. Select the OLEDB/ODBC source option.
4. Click Build to open the Data Link Properties dialog.
5. In the Provider tab, select the Microsoft OLEDB Provider for ODBC Drivers option.
6. In the Connection tab, select the Use Data Source Name option and then select the Outlook DSN in the menu.

Select and Filter Tables and Views

Follow the steps below to use the wizard to import Outlook tables. As you use the wizard to select, filter, and sort columns of Outlook tables, Power Pivot generates the query to be executed.

1. After selecting the DSN in the Table Import Wizard, select the option to select from a list of tables.

2. Click Preview & Filter to select specific columns, sort data, and visually build filters. To include or exclude columns, select and clear the option next to the column name.

   To filter based on column values, click the down arrow button next to the column name. In the resulting dialog, select or clear the column values you want to filter. Alternatively, click Number Filters or Text Filters and then select a comparison operator. In the resulting dialog, build the filter criteria.

3. Return to the Select Tables and Views page of the wizard. You can access filters by clicking the Applied Filters link in the Filter Details column.

Import and Filter with SQL

You can also import with an SQL query. The driver supports the standard SQL, allowing Excel to communicate with Outlook APIs.

1. After selecting the DSN in the Table Import Wizard, select the option to write a query.

2. In the SQL Statement box, enter the query. Click Validate to check that the syntax of the query is valid. Click Design to preview the results and adjust the query before import.

   
3. Finish the wizard to import the data for your chosen query.
