Azure Open Ai service

Question

Hello,

  I have a chatbot in copilot Studio. I connected the copilot to Azure Open AI. Firstly, the connection worked, but it disappeared twice in the last month.  The first time the connection appeared by itself, but now, the connection disappeared on 6 June and is still absent. I have the resource group located on West Europe, but the Azure Search and Azure Open AI are created on France Central because I have my work environment on France. Do I have to change the resource group to France?

If I create a new resource on France, it is possible for my connection to appear again?

Thank you!

Your issue is likely caused by a region mismatch between your Copilot Studio environment (resource group in West Europe) and your Azure OpenAI/Azure Search resources (in France Central). Microsoft Copilot Studio and Azure OpenAI connections are region-sensitive—the integration requires that all connected resources (Copilot Studio, Azure OpenAI, Azure Search) are in the same Azure region or in regions that are explicitly supported for cross-region connections (which is limited).

Why did the connection disappear?

• If your Copilot Studio environment is in West Europe, but your Azure OpenAI and Azure Search are in France Central, the connection may be unstable or unsupported, leading to it disappearing.
• Microsoft may have updated regional policies or backend enforcement, causing previously working cross-region connections to break.

What should you do?

• Best Practice: All resources (Copilot Studio environment, Azure OpenAI, Azure Search) should be in the same Azure region for reliable and supported integration.
• If your work environment and data residency requirements are in France, you should:
  1. Create a new Copilot Studio environment/resource group in France Central.
     1. Create or move your Azure OpenAI and Azure Search resources to France Central (if not already there).
        1. Reconnect your Copilot Studio agent to the Azure OpenAI and Azure Search resources in France Central.

Will creating a new resource in France fix it?

• Yes, if you create all required resources (Copilot Studio environment, Azure OpenAI, Azure Search) in France Central, your connection should appear and remain stable.

Thanks,
