Question

Orchestrate the copilot to send email after receiving a new email

john john Pter 1,570

I have created an new agent with this description:-

User's image

where i define it to trigger when an email get received:-

User's image

and as per the instruction i define it to send an email after receiving the email and answer the user input.

But currently the flow is been triggered but the "Send an email" is not been triggered, any advice?

Thanks

Hi john, the reason your flow is not sending the email is that the “Send an email (V2)” action is not properly connected to the Copilot agent’s output. After the trigger “When a new email arrives (V3)” runs, you need to pass the agent’s response as dynamic content to the email step. In the “Send an email” action, set the subject and body fields to use the agent’s response. Also, make sure the email connector is authenticated with the correct account and has permission to send emails. If the response contains blocked content, Responsible AI filtering may prevent the email from being sent, so start by testing with simple, neutral text like “Summarize this email in one sentence.” Finally, check the run history in Power Automate or Application Insights to confirm whether the email step was skipped due to filtering or configuration issues.

@Karan Shewale i have email connector authenticated correctly, and i allowed the agent to dynamically pick the email subject and the email body.. the Receive workflow is working well, the problem with the Send email, it never get triggered as per the instructions i provided

Hi john, the platform does not auto-send emails just because you wrote that instruction in the agent description. The incoming email does not create a “send email” intent, so Copilot skips that action.

To fix it, add a Send an email (V2) step directly in your Power Automate flow after the Copilot step, and map To, Subject, and Body. If you want it to run every time, make the step unconditional.

Copilot will not trigger outbound mail unless you design the flow to do it. instructions inside the agent description to invoke the action.

If you want this to run automatically for every incoming email, remove dependency on user intent and just call the action unconditionally. You must model the automation path. Copilot does not implicitly send outbound mail based on internal narrative text.

@Karan Shewale who told you this info:-

the platform does not auto-send emails just because you wrote that instruction in the agent description.

As with Orchestration been enabled, this is not the case any more, the agent should work based on the instruction we provide, and it will choose the best tool and topic based on the instructions

Hi John, this isn’t personal input. It’s how Copilot Studio works. The agent description guides intent, but actions like Send Email still need to be explicitly added and configured in the flow. Even with Orchestration ON, Copilot won’t auto-send emails unless that action exists and is wired.

Hi John. Referencing the action in the instruction does not auto-bind or auto-execute it. The instruction only informs the agent that the tool exists. For the orchestration engine to invoke “Send an email (V2)”, the action must be present in the flow and the required fields must be mapped or inferable. Orchestration will not create or execute a tool that is not configured as a callable step.Once the action is added with the To, Subject, and Body parameters defined or dynamically mapped, the agent can select and run it based on the instruction.

@Karan Shewale the action is added with the To ,Subject and Body and i am referencing it inside the instruction not sure, what else i am missing?

Hi John,

Even if the tool is referenced in the instruction, that only makes the action available for orchestration. It does not force execution.

Copilot may still skip the action in cases such as:

Required parameters (To, Subject, Body) cannot be confidently resolved

No clear “send email” intent is detected at runtime

Orchestration safety rules flag ambiguity or compliance risk

To ensure the email is actually sent, the Send an email (V2) action must be fully configured with deterministic values or defaults. This removes ambiguity and enables orchestration to execute the action automatically.

Hi John, did you find a fix? I'm stuck with exactly the same setup. Thanks
