Posted on by CU29041309-1

Hello, dear community.

I want to have Agent in teams, that can send notifications in group chat.

For example, as part of flow:

1. Trigger - When a new email arrives

2. Action - Microsoft Teams → Post message in chat

Here found info it's possible to notify in group chat (Power Automate Documentation)
https://learn.microsoft.com/en-us/power-automate/teams/send-a-message-in-teams
Here - only in personal chat (Copilot Studio Documentation)
https://learn.microsoft.com/en-us/microsoft-copilot-studio/advanced-proactive-message

But Copilot Studio use Power Automate flows.

I'm confused.

Could you clarify please.

Thanks in advance.

Hello CU29041309-1,
The two documents outline different approaches:

Power Automate "Post message in a chat or channel" (Teams connector): This method allows posting to personal chats, group chats, or channels, either as the Flow bot or as yourself.

Copilot Studio proactive message: Here, the agent sends messages using its own bot identity. Currently, this is limited to personal chats only because it requires a per-user conversation reference.

Your choice depends on your needs:
– To have an agent proactively DM a user: Use Copilot Studio proactive message.
– To notify a group chat or channel about an event: Use a Power Automate flow with the Teams connector.
– Having an agent post as itself in a group chat is not supported at this time.

For your use case (new email triggers message in group chat): use Power Automate alone.

Set the trigger to When a new email arrives (V3).

Add the action Post message in a chat or channel using the Flow bot, choose Group chat, select the chat, and compose your message.

Consider adding a Copilot Studio agent only if you want users to interact with it in the chat. The agent can call the same flow internally, but posting messages will always be handled through the Teams connector, not the agent's proactive API.

Hi,

Yeah, this confusion is pretty common when you start mixing agents with flows across Power Automate, Microsoft Teams, and Microsoft Copilot Studio.

What’s happening is that both approaches use Power Automate, but they operate under different capabilities.

If you’re using Power Automate directly, then yes, you can post messages to:

Channel

Group chat

Individual chat

For example:

Trigger: When a new email arrives Action: Microsoft Teams → Post message in a chat or channel

This works fine for group chats as long as:

You specify the chat ID or participants

The flow has permission to post

But when you bring Copilot Studio (Agents/Bots) into the picture, things change a bit.

Copilot Studio supports proactive messaging, but:

It is mainly designed for 1:1 conversations (personal chat)

It does not natively support sending proactive messages to group chats

So even though Copilot Studio uses Power Automate behind the scenes, it still follows bot framework limitations.

That’s why you’re seeing:

Power Automate docs → group chat supported

Copilot Studio docs → only personal chat supported

Both are correct, just in different contexts.

If your requirement is:

Send notification to a group chat → use Power Automate directly

Send message from an Agent → limited to personal chat

If you really want to combine both:

Use Copilot Studio for interaction

Trigger a Power Automate flow

Let the flow post to Teams group chat

But the message will be posted by the flow/connection, not truly “as the agent in the group chat”.

So basically, agents can talk like a person in 1:1 chats, but for group chat notifications, Power Automate is still the reliable way.
