That message means the environment (or the agent) hit its Copilot usage/credit limit — it can show even if this specific agent has “0 sessions” because limits are enforced at the Dataverse environment level (shared across agents) and/or via an agent monthly hard stop. Microsoft labels this as EnforcementMessageC2.
Where to fix it (admin):
Power Platform admin center → Licensing → Copilot Studio
Check the Environments view to see if the environment is within capacity / in overage and review consumption.
In the same area, go to Manage Agents (or agent management) and check whether the agent has a monthly limit set or is over limit/disabled. Increase/remove the limit and re-enable if needed.
If you use Pay-As-You-Go, confirm the environment is properly linked to PAYG and not blocked by billing/spend limits.

Hi @MC-20021819-0,
Just wanted to check in and see if everything is working now. If you still need any help, feel free to let me know.
Also, if the issue is resolved, it would be great if you could mark the answer as solved so others with the same question can find it easily.
Thanks and have a great day!
Hi,
The message “This agent is currently unavailable. It has reached its usage limit” usually indicates that the Copilot usage limit has been reached.
Even if the agent itself shows 0 sessions, Copilot limits are enforced at the Dataverse environment level, not only at the individual agent level. This means usage from other agents or previous activity in the same environment can consume the available Copilot capacity.
Microsoft refers to this as the EnforcementMessageC2 limit message.
You can check and resolve this in the Power Platform Admin Center:
Go to Power Platform Admin Center → Licensing → Copilot Studio
Open the Environments view and review the Copilot capacity/consumption for your environment.
You may also want to check the agent configuration:
Open Copilot Studio → Manage Agents
Verify whether the agent has a monthly usage limit configured or has been disabled after reaching its limit.
If your environment uses Pay-As-You-Go billing, make sure the Azure subscription is correctly linked and not restricted by billing or spending limits.
Once the capacity or limits are adjusted, the agent should become available again.
Hope this helps.
