How to allow Microsoft Copilot Studio Full Agent to access Teams Meeting transcriptions.

Dear Tian,

Good day, and thank you for the detailed explanation and screenshot. As a forum moderator, I genuinely wish I could directly inspect your Copilot Studio environment to diagnose and fix this for you. Unfortunately, my role here is limited to providing general guidance and solutions that can be applied by users. From your description and my research, there are likely two separate issues at play here.

1.The two agent types do not receive the same meeting context

An agent created through the Microsoft 365 Copilot ("lite") experience is a declarative agent. These run on Copilot's own orchestrator and foundation model, and are designed to operate within the context of Microsoft 365 apps. When launched from a Teams meeting recap, the Microsoft 365 Copilot host can therefore supply the current meeting context to that agent.

A full Copilot Studio agent is a custom agent with its own orchestration, knowledge, tools, and channels. Publishing it to Teams makes the agent available there, but it does not automatically pass the transcript of whichever meeting recap is currently open. Custom agents retrieve data through their configured knowledge sources and tools, and simply enabling the Teams connectors does not by itself provide the active meeting ID or transcript to the conversation.

This is why identical instructions do not produce identical behavior. Instructions tell the agent what to do with information that is available to it, but they do not grant access to the transcript or supply the meeting identifier needed to retrieve it.

It is also worth noting that the Work IQ Teams tool currently documents operations for chats, channels, teams, members, and messages. Meeting transcript retrieval is not listed among its supported operations, so that tool alone will not give your agent what it needs.

2.The ConnectorAuthorizationError points to a failing tool connection

Your screenshot indicates that the agent attempted to invoke a connector or tool but could not obtain or use the required authorization. Please check the following in Copilot Studio:

1. Open the full agent and select Settings.
2. Select Connection Settings.
3. Review every connection used by the Teams, Microsoft 365, Power Automate, or custom-connector tools.
4. Look for connections marked not connected, expired, stale, deactivated or connection error
5. Reauthenticate or replace the affected connection.
6. Save and republish the agent.
7. Start a new agent conversation in Teams and complete any connection or consent prompt.

Microsoft documents these connection states and requires an active, authenticated connection before an agent can use the associated tool.

If a tool uses the signed-in user's credentials, the agent should be set to Authenticate with Microsoft, and the tool configured for User authentication. One important detail: Microsoft explicitly states that if you have the Teams channel enabled, you must follow the Configure single sign-on with Microsoft Entra ID for agents in Teams instructions. Failing to configure Teams SSO correctly causes users to always fail authentication when using the Teams channel. Given the error you are seeing, this is worth verifying carefully. Please also note that authentication changes only take effect after the agent is republished.

Your tenant administrator may also need to:

• Approve the agent and connector
• Grant required Entra ID consent
• Verify that Power Platform data-loss-prevention policies permit the connector combination
• Confirm that the user is permitted to access the transcript

Given the complexity here, I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
