Configure an integration application in Microsoft Entra ID (Azure AD) for the Splunk Add-on for Microsoft Office 365

In order to gather data from the Office 365 Management Activity API and the Office 365 Service Communication API using this add-on, you must first create an integration application in Microsoft Entra ID. This application securely authenticates the Splunk Add-on for Microsoft Office via the OAuth2 protocol, so that it can access and gather the data according to the services and permission levels that you specify.

In order to create an integration application, you need the following prerequisites:

  • A Microsoft Azure account with administrator permissions to delegate roles to the application user. Your Microsoft Azure subscription must be linked with your Office 365 subscription by using the same login id.
  • A security token for the Microsoft Cloud Application Security Portal. See the Managing API tokens topic in the Microsoft documentation.

Create an Application in Microsoft Entra ID

  1. Follow the instructions in the Create a Microsoft Entra ID application topic in the Microsoft documentation to create an integration application.

  2. When creating your application, make a note of the following parameters. They will be needed to Configure a Tenant in the Splunk Add-on for Microsoft Office 365.

    • Directory ID (Tenant ID)
    • Application ID (Client ID)

  3. Set the Application permissions in the API Permissions > Add a permission pane of the Azure Active Directory Office 365 Management API configuration. These permissions are required for the Splunk Add-on for Microsoft Office 365.
