Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Enter /cost in Cowork; if that command is available for your personal account, it shows the approximate credit cost of a task, credits used this month, and credits remaining for the current month.^1^
What Microsoft 365 Premium includes
Microsoft publishes the Cowork allowance for an individual Microsoft 365 Premium subscription only as “Extensive usage,” not as a specific number of tasks, messages, hours, or credits. Cowork is currently listed as a preview feature available to Premium and Pro subscribers in the US and Canada, with availability varying by platform and device.^2^
Therefore, there is no publicly documented fixed figure such as “100 Cowork tasks per month” that can be reliably applied to every Premium subscriber.
How usage is measured
Microsoft distinguishes between:
- Feature limits: The number of times a particular AI feature can be used during a specified period.
- AI credits: Monthly usage allotments consumed across eligible Microsoft 365 and Windows AI experiences.
The applicable method can vary by feature, entry point, and system conditions, and Microsoft says limits can change over time.^2^
For Cowork specifically, /cost may expose credit-based accounting for your account. This is more informative than counting prompts manually because a complex Cowork task can involve multiple model responses or actions. It reports account-specific consumption; it does not establish a guaranteed fixed quota included with every Premium subscription.
Also check:
- Sign in to the Microsoft account that owns the Premium subscription.
- Open Services & subscriptions.
- Review the AI-credit or feature-limit status shown for the subscription.
Microsoft identifies this page as the location for checking limits and AI-credit status.^2^ AI benefits belong to the subscription owner and cannot be shared with other members of the Premium subscription.^3^
When it resets
- If
/costreports credits used this month, that Cowork credit counter is operating on a monthly period. - Microsoft documents AI credits generally as monthly allotments.
- Microsoft does not publish a universal reset day or timestamp for the individual Premium Cowork limit, nor does it state that the reset follows the subscription renewal date.
- A monthly AI-credit period does not prove that every Cowork warning is an AI-credit warning; the notice could instead reflect a feature-specific or capacity-related limit.
Your February 11 annual billing date therefore should not be assumed to be the Cowork reset date.
If neither /cost nor Services & subscriptions displays the allowance or next reset, contact Microsoft consumer support and provide a screenshot of the warning, the account’s subscription name, and the date it appeared. Support can investigate the account-specific notice, although the published policy does not guarantee that an exact internal quota or reset timestamp will be disclosed.
