Hi,
From the screenshots you shared, it looks like the trigger “When a new email arrives (V3)” is working correctly and the flow is successfully calling the Copilot action. That means the flow itself is running as expected.
One important detail is that the action “Send a prompt to the specified copilot for processing” only sends the email content to the Copilot agent and returns a generated response. It does not automatically send that response back as an email.
Because of this, you usually need an additional Outlook step in the flow to send the reply.
A typical pattern for this scenario would be:
Trigger: When a new email arrives (V3)
Send the email content to Copilot: Send a prompt to the specified copilot for processing
Send the reply email: Add an Outlook action such as Reply to email (V3) or Send an email (V2) and use the response from the Copilot step as the email body.
For example:
To: From (sender address from the trigger)
Subject: Re: Subject from the trigger
Body: Response returned from the Copilot action
This allows the Copilot agent to generate the response using your knowledge base, and then the Outlook action sends that response back to the original sender.
If you'd like, you could also add a Compose step after the Copilot action to confirm that the response text is being generated before sending the email.
Hope this helps.
