Microsoft will implement changes to the behavior of agents in Copilot Studio once the purchased messages in message packs have been exhausted. This new policy affects all tenants utilizing Copilot Studio message packs for conversational and autonomous custom agents.
Until now, the situation was unclear when Copilot Studio agents were using more than the available messages from a Copilot Studio message pack in a month.
Microsoft could never answer this question to us, or they mention what the documentation recommends. Customers should configure Copilot Studio Pay-as-you-go as an alternative meter.
Copilot Studio capabilities are licensed via message packs, where one message pack equals 25,000 messages a month. For extra capacity, we recommend signing up for pay-as-you-go to ensure business continuity. The pay-as-you-go meter starts counting after you exhausted your message pack entitlements.
If this is not configured, what happens if customers use more than the monthly message pack capacity or what is the acceptable limit? The question was never answered by Microsoft. This usage enforcement will change it.
Timeline
The change will take effect on Wednesday, 30 April 2025.
How does this affect your Copilot Studio agents and users?
When a tenant exceeds 125% of their message pack capacity in any month, agents will cease to provide expected responses to new interactions. Instead, users will receive the message: “I’m sorry, I’m not sure how to help with that”. All subsequent attempts to engage the agent will be rejected until the capacity is increased or reset.
Organizations should keep in mind that there is a delay between the Copilot Studio messages consumption vs capacity report in the Power Platform admin center. The report has a 24-hour delay.
