Summary

This guide details how to integrate Microsoft Copilot Studio with an existing Azure AI Search index to provide retrieval-grounded, enterprise-secure responses. The process enables business users to obtain reliable answers from enterprise documents without requiring additional data engineering or re-platforming knowledge stores. The integration assumes an Azure AI Search service is already deployed with an index containing vectorized content, including manuals, PDFs, policies, and FAQs, with ingestion, embeddings, and indexing already handled. The steps involve collecting Azure AI Search connection details (Endpoint URL and Admin Key), adding Azure AI Search as a knowledge source within Copilot Studio, and then testing the copilot to verify grounded responses and citations. This approach supports low-code agility while maintaining enterprise-grade security and governance within Azure.

Key takeaway

For AI Engineers or Solutions Architects building enterprise copilots, integrating Copilot Studio with an existing Azure AI Search index offers a rapid path to grounded, secure answers. This method avoids re-platforming or new data pipelines, allowing your team to quickly deliver business value by leveraging pre-existing knowledge stores. Ensure your Azure AI Search index is prepared with vectorized content and embeddings before starting the Copilot Studio connection.

Key insights

Integrate Copilot Studio with Azure AI Search for grounded, secure enterprise answers using existing knowledge bases.

Principles

• Reuse existing infrastructure for quick wins.
• Separate data ownership from copilot experience.
• Maintain enterprise security with low-code agility.

Method

Connect Copilot Studio to an existing Azure AI Search index by providing the endpoint URL and admin key, then select the index to enable retrieval-augmented generation from enterprise documents.

In practice
