Copilot Studio agent hits usage limit after 1 request in new environment

Posted on by 遥佐-28110409-0

I am creating an FAQ bot using Copilot Studio.

I created a new environment and imported a solution that had been exported from the previously used environment.

When I send a question to the chat in the new environment, the first question is answered normally. However, if I send an additional question immediately afterward, the message “This agent is currently unavailable. The usage limit has been reached. Please try again later.” is displayed. If I wait about three minutes and then send another question, a normal response is returned.

Please let me know the cause of this issue and how to resolve it.

Is it possible that by creating a new environment, the pay-as-you-go plan that was used in the original environment is no longer available?

Hello 遥佐-28110409-0 ,

Thanks for sharing the details this is a common gotcha when moving Copilot Studio solutions to new environments. The "This agent is currently unavailable. The usage limit has been reached" error after just one request (with a ~3-minute cooldown) is almost always due to rate limiting on generative AI messages in low-capacity environments like trial/sandbox. Your new environment likely started as a trial/developer one without pay-as-you-go (PAYG) enabled, which caps GenAI at 10 RPM / 200 RPH plenty for the first message but throttles the immediate second one. PAYG from the original env does not carry over; it's configured per-environment and only works on production/sandbox types.

Quick Fix: Enable PAYG Capacity

Go to Power Platform admin center (admin.powerplatform.microsoft.com) > Environments > select your new env > Capacity tab.

Under Billing, click Add billing plan > Link your Azure subscription (ensure PAYG is active there—no spending limits).

This unlocks 100+ RPM and pay-per-message (~$0.01/msg) for overages.

Refresh and test—should handle back-to-back requests fine.

Verify & Monitor

Check current quotas/usage in the Capacity tab or Copilot Studio > Analytics > Capacity.

If still hitting limits post-PAYG, your FAQ bot might be credit-heavy (e.g., multiple generative nodes); simplify topics (<1,000) or use analytics to spot hogs.

For production, consider prepaid capacity packs (1 pack = 25k messages/mo) via Azure Marketplace.

Trial envs are great for dev but throttle fast—switch to sandbox/production for real testing. If issues persist after PAYG setup, share your env type/capacity screenshot or open an Azure support ticket (free for Power Platform). Hope this gets your bot chatting smoothly! Accept if helpful. 😊

Best regards,
Jerald Felix

Hi @遥佐-28110409-0,

This issue occurs because the agent in the new environment is hitting Copilot Studio usage quotas / throttling limits.
You can review and manage the limits from the Power Platform admin center:
Licensing → Copilot Studio → Summary → Manage agents → Select the agent → Set limits

For more details on quotas and how to request a limit increase, please refer to the following articles:

I hope this information helps! If it does, please consider giving a 👍.
If this solved your issue, please mark it as ✅ Verified Answer
