Microsoft extends undisclosed usage restrictions on Copilot Chat for enterprise users

Microsoft is extending undisclosed usage caps to additional Copilot Chat features for enterprise users who already pay for Microsoft 365 subscriptions but do not hold separate Microsoft 365 Copilot licenses, restricting access to certain AI capabilities and nudging users to upgrade to a paid Copilot-specific license.

Before the change, commercial users could access Copilot Chat at no additional cost through eligible Microsoft 365 business and enterprise subscriptions, including Business Basic, Business Standard, Business Premium, Office 365 E3 and E5, and Microsoft 365 E3 and E5.

While Microsoft already applied fair-use limits to certain capabilities, such as image generation, it is now extending usage restrictions to additional Copilot Chat features, without specifying which capabilities will be affected or disclosing the thresholds governing their use.

Under the new usage policy, users who reach a feature’s fair-use limit will receive an in-product notification indicating when access will become available again. Administrators, too, cannot view, configure, or override them, according to a portal that archives Microsoft 365 Message Center notifications.

The rollout began November 2 for enterprises with 2,000 or fewer Microsoft 365 seats and is scheduled to begin November 9 for organizations with more than 2,000 Microsoft 365 seats.

Unpredictable limits could disrupt productivity

The undisclosed usage caps on Copilot Chat are likely to reduce productivity for business users and push employees towards alternative tools with similar capabilities, said Pareekh Jain, principal analyst at Pareekh Consulting.

Primarily because of the unpredictability of the usage caps, echoed Nhat Bui, deputy director of engineering at Scopic Software. “If someone knows they get 50 requests a day, they plan around it. If a feature stops working mid-afternoon without warning and they can’t tell when or why, they stop relying on it for anything that matters.”

“People only build AI tools into their daily work once they trust it will be active when they need it. A tool that sometimes isn’t available becomes a nice extra, not part of how the work gets done,” Bui added.

The risk of users abandoning AI tools because of unpredictable usage limits is already evident in AI coding environments, where developers who hit limits midway through tasks often have to switch tools and rebuild their context, Bui further added.

Such tool-switching could also create a broader governance challenge for CIOs, as employees frustrated by usage restrictions turn to alternative AI tools that fall outside their enterprises’ approved technology environments, increasing the risk of shadow AI, Jain pointed out.

The bigger challenge for CIOs will be budgeting and managing expectations, said Manoj Chandra Jha, principal analyst at Nord-IQ Research. “They are being asked to drive AI adoption while planning around limits they can’t clearly see, which makes budgeting and managing expectations much harder.”

As a solution to the undisclosed usage caps, CIOs could use internal usage data to identify employees who rely most heavily on Copilot Chat and prioritize them for paid licenses, while communicating the limitations of the included offering to other employees, Jha said.

“CIOs should also press Microsoft for greater transparency around usage thresholds to make AI adoption and budgeting more predictable,” he added.

Usage limits could also create risks for Microsoft

Further, analysts pointed out that the undisclosed limits might not only be a problem for CIOs but also for Microsoft, from a competitive differentiation standpoint.

As enterprises increasingly factor cost predictability into their AI purchasing decisions, providers that offer transparent usage thresholds and pricing could gain a competitive advantage, Jain said.

The undisclosed usage caps combined with the nudge to upgrade to a paid Copilot-specific license could also attract regulatory attention in Europe, where Microsoft has previously faced scrutiny over how it bundles products and uses its established Microsoft 365 customer base to distribute additional services, according to Jha.

In June 2024, the European Commission issued its preliminary findings, saying Microsoft had breached EU competition rules by bundling Teams with its Microsoft 365 and Office 365 productivity subscriptions.

The Commission had argued that including Teams with these subscriptions gave the collaboration platform a distribution advantage over competing services, including Slack.

Microsoft subsequently proposed changes to its licensing and pricing arrangements, including offering Microsoft 365 and Office 365 subscriptions without Teams at lower prices. The company also agreed to improve interoperability with competing collaboration tools.

In September 2025, the European Commission accepted Microsoft’s commitments, bringing the investigation to a close without imposing a fine. The commitments included lower-priced subscriptions without Teams and measures to improve interoperability and data portability.

In the case of Copilot, regulators could examine whether the new restrictions give Microsoft’s paid AI assistant an unfair advantage over competing AI providers seeking access to the same enterprise customers, Jha said.

However, usage restrictions are not inherently anti-competitive, Jha pointed out. Even so, regulators could scrutinize whether Microsoft is leveraging its control over the Microsoft 365 distribution channel to steer customers towards Copilot at the expense of competing AI assistant providers, Jha added.ComputerworldRead More
