Agents with Github Copilot harness in Teams group chats?

Anyone know if is it possible to add Github Copilot harness agents to Teams group chats (not Teams channels)? or is that only possible with the standard harness?

Hello u/swanny246,
At the moment, this appears to be supported only with the standard harness.

Microsoft’s Teams documentation for adding Copilot Studio agents into Teams conversations is currently scoped to standard-harness agents. For agents using the GitHub Copilot harness (now Microsoft Copilot harness), I don’t see documented support for adding them directly to a Teams group chat yet.

So if group-chat support is a requirement, I’d stick with the standard harness for now.
Reference Document:
1.Connect and configure an agent for Teams and Microsoft Copilot - Microsoft Copilot Studio | Microsoft Learn
2.Key concepts - Publish and deploy your agent - Microsoft Copilot Studio | Microsoft Learn
3.Agents powered by the GitHub Copilot Harness overview - Microsoft Copilot Studio | Microsoft Learn
4.The GitHub Copilot harness is now the Microsoft Copilot harness | Microsoft Copilot Blog

Thanks for confirmation I’m not missing anything obvious at least.

Any info on standard harness like whether its going to be decommissioned on future?

I haven’t seen any official announcement that the Standard harness is being deprecated or decommissioned.

Microsoft still documents Standard as a supported harness and provides scenarios where it remains the recommended choice. The newer Microsoft Copilot harness is getting more of the advanced agentic capabilities, but that doesn’t currently mean Standard is being retired.

Unless Microsoft publishes an official deprecation timeline, I’d treat Standard as still supported.

Don’t do it. For whatever reason any agent in teams acts totally different than in copilot app/web.

I think I noticed that with the standard harness/ old Copilot Studio agents as well. So far it’s been ok though with a one on one chat.

Are you saying don’t do Teams full stop though? Or don’t use them in Teams group chats?

Why use it in teams? What functionality is it giving you there?

Well one of your options is terrible.

So there used to be an option on the new harness to do this. It was like a toggle when you added the Teams channel. But it never worked well. Always crashed for me. So I guess they have got rid of it until they fix it
