Even with a paid or “unlimited” Copilot-related plan, usage is still governed by technical limits and quotas to protect service reliability and manage capacity.

From the provided information, there are several types of limits that can cause a “you’ve reached your limit” or similar cutoff message:

Rate limits (requests per minute/hour)
- For Copilot-based services built on Dataverse (such as Copilot Studio or Copilot for Service), there are hard rate limits on how many messages/requests can be sent per minute per environment.
- Example: Copilot for Service has a quota of 800 messages per minute per Dataverse environment. When that quota is hit, further messages are blocked and users see a failure notice and are prompted to retry.
- Copilot Studio agents also enforce per-minute and per-hour quotas for generative AI messages. When those quotas are reached, users see errors like “usage limit for search and summarize has been reached” or “your agent reached the maximum number of generative answers responses.”
Capacity/credit limits (Copilot credits / AI credits)
- Copilot Studio measures usage in Copilot credits, where each interaction (request that prompts a response/action) consumes a credit. If consumption exceeds the available capacity in the environment, overage enforcement is triggered and the agent becomes unavailable with a message that it has reached its usage limit.
- For Microsoft 365 Personal/Family/Premium plans, AI features (including Copilot in apps like Word, Excel, OneDrive, etc.) are governed by AI credits and feature limits. Each AI action (for example, summarizing a document, generating text, or using Actions/Vision) consumes credits. When feature limits or AI credits are exhausted for a period, usage can be blocked until the limit resets.
Plan-specific feature limits
- Different subscriptions have different caps for specific AI features. For example, Copilot for Service has Power Platform request limits per 24 hours depending on subscription type.
- For consumer Microsoft 365 plans, feature limits and AI credits vary by plan (Personal, Family, Premium) and by feature, and may also change over time as models and capabilities evolve.
Free vs. paid tiers in some clients
- In some environments (for example, GitHub Copilot Free in Visual Studio), there are explicit monthly usage limits for chat and inline suggestions. When those are reached, Copilot functionality is reduced until the monthly reset or an upgrade to a higher plan.

Because of these mechanisms, a paid or “unlimited” label does not mean there are no technical or operational limits. The most common reasons for being cut off are:

Hitting a rate limit (too many requests in a short time window).
Exhausting credits or capacity allocated to the environment or subscription period.
Reaching a feature-specific cap tied to the current plan.

To move forward in this situation:

Check which Copilot product and plan is in use (for example, Microsoft 365 Personal/Family/Premium, Copilot Studio, Copilot for Service, or GitHub Copilot in an IDE).
Review the applicable limits:
- For Copilot Studio or Copilot for Service, review quotas and Copilot credits in the Power Platform admin center and consider adding capacity or switching to pay-as-you-go if applicable.
- For Microsoft 365 consumer plans, review AI credits and feature limits under Services & subscriptions in the Microsoft account.
If limits are being hit regularly and capacity is already maximized under the current plan, contact Microsoft Support or the appropriate admin channel to review options (additional capacity, pay-as-you-go, or plan changes) and to verify whether any throttling or overage enforcement is active on the tenant or environment.
