This behavior is expected in most cases and is usually caused by how “Bring Your Own Machine” (BYOM) is scoped and registered in Power Automate vs Copilot Studio.
Even if your machine is visible in the Power Automate Machines list, it will not automatically appear in Copilot Studio unless a few key conditions are met.
Here are the most common causes and how to fix them:
1. Machine is not part of a Machine Group
Copilot Studio does not list individual machines. It surfaces only machines that are part of a Machine Group.
Fix:
- Go to Power Automate → Machines
- Create a Machine Group
- Add your machine to that group
2. Environment mismatch
Machines are environment-specific. If your machine is created in a different environment than your Copilot Studio agent, it will not be visible.
Fix:
- Verify that:
- The machine (or machine group)
- The Copilot Studio agent
are in the same Power Platform environment
3. Missing permissions
Even if the machine exists, you must have the correct permissions on the machine group.
Fix:
- Ensure you are:
- Owner or User of the machine group
- With proper access to use desktop flows
4. Machine not properly registered or offline
The machine must:
- Have Power Automate Machine Runtime running
- Be online and connected
Fix:
- Open the machine runtime and verify it is connected
- Check status in Power Automate → Machines
5. BYOM support limitations
In Copilot Studio, the “Bring Your Own Machine” option is still evolving. In some cases:
- Only specific configurations (like machine groups) are supported
- Standalone machines are not selectable
What your screenshot shows:
- The dropdown correctly exposes "Bring-your-own machine"
- But no machine is listed because nothing eligible (i.e., no valid machine group in the same environment) is available
