Publishing Copilot Studio Agent Assistance

Posted on by CU04022236-0

Hello,

I made a Copilot Studio agent and created an adaptive card on conversation start. I published the agent to M365. When I open M365, I see that the agent appears, but the adaptive card is not showing up and the flow is not executing. When I test the Copilot Studio agent, I am able to see the adaptive card appear, but when I publish the agent to M365, the adaptive card is not displaying. Are there any additional steps to follow to resolve this. Thanks!

Move Adaptive Card to First User Interaction:

Instead of sending the adaptive card on “conversation start,” trigger it after the user’s first message or greeting. This is more reliable across channels.
Republish and Re-add Agent:

After making changes, republish your agent.
Remove and re-add the agent in M365 if possible, to ensure the latest version is loaded.
Test in M365 Channel:

Always test in the actual M365 environment, as the test chat in Copilot Studio is more permissive.

Hi,

This behavior is expected in some cases because “conversation start” triggers do not always execute the same way across channels, especially in M365 Copilot.

In Copilot Studio test chat, the runtime is more permissive, but when the agent is published to M365, the conversation lifecycle is slightly different, and the initial system-triggered message may not invoke Adaptive Cards or flows reliably.

As per Microsoft guidance, it is recommended to trigger actions after the first user interaction instead of on conversation start, as not all channels guarantee execution of conversation start logic.

You could try the following:

Move the Adaptive Card to trigger after a user message (for example a greeting like “Hi”)

Ensure the topic is configured to trigger on user input instead of only system start

Republish the agent after changes

Remove and re-add the agent in M365 to refresh the latest version

Also, always validate behavior in the target channel (M365), since the Copilot Studio test environment may behave differently.

Hope this helps, if this response was helpful, you can mark "Was this reply helpful?" as Yes, and if it resolves your issue, please consider marking it as Verified.

Hi @CU04022236-0,

The display issue is caused by the Adaptive Card JSON version being too high. The test pane supports up to version 1.6, but live M365 Copilot channels cap at 1.5 — downgrading to 1.4 fixes it for most users.

1. In Copilot Studio, open the card JSON and change "version": "1.6" (or higher) to "version": "1.4"
2. Validate the card at adaptivecards.io/designer using the Teams host
3. Save and republish the agent to the M365 Copilot channel
4. Clear the M365 cache (%localappdata%\Microsoft\M365Copilot), refresh m365.cloud.microsoft, and start a new chat

Your JSON header should look like this:

{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.4",
"body": [...]
}

Best regards,

Valantis
