(Updated) Microsoft 365 admin center: Prepurchase capacity packs for Microsoft 365 Copilot Chat [MC1155434]

Message ID: MC1155434 (Updated)

Updated October 7, 2025: We have updated the timeline to show as intended as well as added additional details. Thank you for your patience.     

Introduction

To help organizations manage metered consumption costs for Microsoft 365 Copilot Chat, we’re introducing support for prepaid Capacity Packs in the Microsoft 365 admin center (MAC). This feature enables global administrators to use prepaid message bundles before incurring pay-as-you-go (PAYG) charges.

This update applies specifically to Copilot Chat environments provisioned via the Power Platform admin center (PPAC), including declarative or custom Copilot agents built using Microsoft Copilot Studio.

Each Capacity Pack includes 25,000 Copilot messages per month, which can be allocated to Copilot Chat environments via PPAC. Once enabled, MAC will prioritize usage from these prepaid packs and automatically switch to PAYG when capacity is exhausted.

Admins can monitor usage in PPAC, including:

• Total messages consumed
• Remaining prepaid capacity
• Message allocation per environment

This update is associated with Microsoft 365 Roadmap ID 496139.

When this will happen

• Targeted Release: We will begin rolling out in late September 2025 and expect to complete by late September 2025.
• General Availability (Worldwide): We will begin rolling out in late September 2025 and expect to complete by early October 2025.

How this affects your organization

This feature helps organizations manage Copilot Chat costs by allowing the use of prepaid message bundles before PAYG charges apply. It supports:

• Improved budget control through prepaid capacity
• Simplified billing setup in MAC
• Automated provisioning for Copilot Chat environments
• Enhanced cost visibility and governance through detailed usage reporting in PPAC

The feature also supports unlicensed users and includes automatic fallback to PAYG when prepaid capacity is exhausted, ensuring uninterrupted service.

Existing pay-as-you-go billing methods will remain available and unchanged. Capacity Packs offer an additional prepaid option and do not replace current billing models.

The feature is on by default and requires no manual configuration to begin using.

What you can do to prepare

No admin action is required before rollout.

Compliance considerations

No compliance considerations identified, review as appropriate for your organization.
