Failed to Publish Copilot Studio Agent
Hello! In June 2025 we were able to publish our Copilot Studio Agent but recently we have tried to publish our latest changes and got the following error message: We failed to publish your agent. ...
Thanks pradejain​!
I had to rebuild from scratch the agent, all your suggestions were either greyed out or not available in the old agent settings.
With the new agent and same settings the agent has been published successfully.
Mistery unsolved!
The fix that worked for a colleague was to go to Channels > Telephony and turn it on and then off again, which is what Copilot suggested.
Edit: I've just come across this issue myself and and doing the above hasn't worked. Going to log a ticket with Microsoft.
