ConnectorRequestFailure error when Copilot Agent is published to Teams

Hey Team,

I’ve created a Copilot agent in Copilot Studio that connects to Dynamics 365 Finance and Operations to create customer master records. When I test the agent inside Copilot Studio (Test your agent), everything works perfectly.

However, once I publish the agent to Microsoft Teams and try to create a customer master record, I receive this error message:

An error has occurred. Error code: ConnectorRequestFailure Conversation Id: [ID] (UTC: [timestamp])

It seems like the connector is timing out or failing to connect when the agent runs through Teams, even though it works fine in the Copilot studio test environment (Test your agent)

I’ve already tried:

Reconnecting the D365 connection

Republishing the agent

Verifying that the same environment is used

Checking that the connector timeout isn’t exceeded

But the issue still persists.

Could anyone help me understand:

Why the connector might be failing only when accessed from Teams?

Whether there are different timeout limits or authentication paths when an agent is run from Teams?

Any recommended steps to resolve the ConnectorRequestFailure error in this scenario?

Thanks in advance for your help!
