Failed to Publish Copilot Studio Agent

Hi Woody​ 

We ran into this recently, too, and the error is basically telling you that your Copilot Studio agent is set up to use features that now require Dynamics 365 Contact Center — things like Telephony integration or the newer NLU+ (enhanced natural language understanding).

A few months ago, you could publish without that environment being provisioned. Microsoft has since tightened the rules, so now the publishing process checks for it.

What this means:

• If you actually need those voice/telephony or NLU+ features, your tenant admins will have to provision Dynamics 365 Contact Center in that environment. That’s a licensing and setup step at the tenant level.
• If you don’t need them, you can go into your agent’s settings in Copilot Studio, turn off the Telephony/NLU+ options, save, and then try publishing again.

How to fix without provisioning Contact Center

• Opening the agent in Copilot Studio.
• Go to Settings → Speech (or the equivalent “Voice”/“Telephony” settings).
• Turning off all Telephony/NLU+ options — especially “Optimize for voice” — and saving.
• Waiting a short while (some time, a few hours) before trying to publish again.

Please mark as resolved if this answers your question.
