What is Microsoft 365 Copilot Connector Checker?

Copilot Connector Checker is a lightweight, self-service validation tool designed to help IT teams and administrators quickly verify that all prerequisites for Copilot connectors are correctly set up before configuring a connector for production. Think of it as a pre-flight check for your connector deployment. 

Copilot connectors allow external business systems—such as ServiceNow, Confluence, and other third-party platforms—to be indexed into Microsoft Graph so that Microsoft 365 Copilot and related intelligent experiences can discover and reason over line-of-business data. 

Why You Need Copilot Connector Checker 

Deploying a Copilot connector often requires configuring: 

• Authentication type (Basic or OAuth) 
• API access permissions 
• Connectivity settings 
• Table-level permissions 

If even one setting is incorrect, the connector may fail to function without clear warning, or result in the copilot not being able to retrieve all external data. 

Copilot Connector Checker reduces guesswork by automatically testing these requirements, allowing problems to be identified early on. 

Key Benefits 

💡 Fast, guided validation – Check connectivity and setup in minutes. 
🔍 Clear diagnostics – Get actionable results without digging through logs. 
⚙️ Simple UI – No deep technical knowledge required to run the tests. 
📈 Immediate feedback – See where issues exist and recommended next steps. 

How Copilot Connector Checker Works 

Using the tool is straightforward: 

1. Open the Copilot Connector Checker web interface. 
2. Select the authentication type (Basic or OAuth, which is recommended). 
3. Enter the required connection parameters (e.g., endpoint URL and credentials). 
4. Click “Perform Test”. 

Once executed, the tool will: 

• Validate connectivity 
• Verify credentials 
• Check table-level permissions 
• Provide diagnostic summaries 
• Recommend next steps if issues are found 

This workflow helps administrators identify setup issues before committing to a full connector deployment. 

Supported Connectors and Roadmap 

At launch, Copilot Connector Checker supports testing the ServiceNow Knowledge Base (KB) connector, with specific instructions for that service.

Microsoft states that it will support more connectors in the future, making this tool more comprehensive across the enterprise ecosystem. 

Who should use the Copilot Connector Checker? 

This tool is especially helpful for: 

• Microsoft 365 administrators preparing to deploy Copilot connectors 
• IT professionals validating access and permissions 
• Organizations integrating external systems into Microsoft Graph 
• Teams planning large-scale Copilot rollouts 

By reducing setup errors early, Copilot Connector Checker accelerates deployment and increases confidence that your connectors are ready for production use. 

Conclusion 

The Copilot Connector Checker is a key component that strengthens the Microsoft 365 Copilot ecosystem by simplifying and systematically verifying potentially complex installation processes

With its fast and clear automated analysis system, this tool enables the team to: 

✔ Verify identity and connection. 
✔ Analyze configuration issues from the early stages. 
✔ Create a stable and reliable AI experience when working with external data. 

As more connectors are supported in the future, Copilot Connector Checker will become an essential tool for any organization that wants to efficiently and reliably centralize enterprise-level knowledge through Microsoft 365 Copilot in a production environment.
