Microsoft is extending its fair-use limits in Copilot Chat, the AI chat bundled at no extra charge into Microsoft 365 business plans, to more features for employees who do not have a paid Microsoft 365 Copilot licence. It told partners in its Partner Center on November 4, without saying which features are capped or at what thresholds. Until now the limits applied only to a few features, such as image generation.

The cuts took effect on November 2 for organisations with up to 2,000 seats, and reach larger organisations from November 9. Anyone who hits a limit sees a notice saying when the feature will be available again — an answer already being written is not cut off — and in most organisations the notice includes a button to ask the admin for the paid licence. The change covers Copilot Chat on the web, desktop and mobile.

Admins cannot look up or change the caps: Microsoft says it does not publish them because they may change, and that they shift during the day. Computerworld reports analysts warning that unpredictable limits may cut productivity and push staff toward AI tools the company has not approved.
