Publishing a CoPilot Agent

You don’t need to reinstall the Copilot in Teams every time you make changes in Copilot Studio. Once you make modifications and click "Publish", the changes are automatically reflected for end users, as long as:

The bot is already installed in Teams.

You haven’t changed the app ID or environment.

No new permissions are required that users would need to manually accept.

However, there are a few exceptions where additional action might be needed:

If you change the app’s permissions (e.g., access to Microsoft Graph), users may need to re-consent.

If you modify the Teams channel configuration (like the bot’s manifest), you might need to manually update the app in Teams.

If you're using development versions or different environments, make sure you're publishing in the correct environment and that the bot is installed from there.
