Hi,

If your Copilot Studio agent is working correctly from the Copilot menu but not responding in Microsoft Teams chat, there are a few common causes and configuration checks you can perform to resolve the issue:

1. **Check Personal Chat Scope Configuration**
In Copilot Studio, navigate to **Settings > Channels > Microsoft Teams** and ensure that the **Personal scope** is enabled. If this scope is not active, the agent may not respond in 1:1 Teams chats even though it works in the Copilot tab[1](https://learn.microsoft.com/en-us/answers/questions/2265391/copilot-agent-does-not-respond-in-teams-chat-but-d).

2. **Install the Agent as a Personal App in Teams**
Go to **Apps** in Microsoft Teams, search for your agent, and install it as a **personal app**. Installing it only as a tab or in a team channel may not be sufficient for chat functionality[1](https://learn.microsoft.com/en-us/answers/questions/2265391/copilot-agent-does-not-respond-in-teams-chat-but-d).

3. **Review Teams Admin Policies**
Your organization’s Teams admin settings might be blocking custom apps. In the **Teams Admin Center**, check:
- **Teams apps > Org-wide app settings**: Ensure “Let users interact with custom apps” is set to **Allow**.
- **Teams apps > Setup policies**: Under the policy applied to your users (e.g., Global), make sure “Upload custom apps” is turned **on**[2](https://www.thewindowsclub.com/copilot-not-working-in-teams-fix).

4. **Enable Authentication for Teams Channel**
In Copilot Studio, go to **Settings > Security > Authentication** and ensure that authentication is properly configured (typically via Azure AD). Then, under **Settings > Channels**, select **Microsoft Teams** and enable “Use when a user is signed in.” This ensures the agent can access necessary resources with the correct permissions[2](https://www.thewindowsclub.com/copilot-not-working-in-teams-fix).

5. **Republish and Update the Agent**
After making changes, republish the agent in Copilot Studio and update the app in Teams (under “Built for your org”) to ensure the latest configuration is applied[1](https://learn.microsoft.com/en-us/answers/questions/2265391/copilot-agent-does-not-respond-in-teams-chat-but-d).

6. **Check for Usage Limits or Connection Issues**
Some users have reported inconsistent behavior due to agent usage limits or connector authentication issues. If your agent connects to external systems (e.g., SharePoint, Confluence), verify that all users have valid connections and permissions[3](https://learn.microsoft.com/en-us/answers/questions/5573696/copilot-studio-agent-not-responding-consistently-i).

7. **Clear Teams Cache or Try Web Version**
If the issue persists, try accessing the agent via the **Teams web app** or clear the Teams cache on the desktop client. This can resolve local client-side issues[4](https://thegeekpage.com/copilot-is-not-working-in-microsoft-teams-how-to-fix/).

For further guidance, you can also refer to the official Microsoft documentation on [Copilot Studio agent deployment in Teams](https://learn.microsoft.com/en-us/answers/questions/2265391/copilot-agent-does-not-respond-in-teams-chat-but-d)[1](https://learn.microsoft.com/en-us/answers/questions/2265391/copilot-agent-does-not-respond-in-teams-chat-but-d).

Thanks and best regards,
Daniele
