Enterprise customers with Microsoft 365 subscriptions—who lack standalone Microsoft 365 Copilot licenses—will now face undisclosed limits on Copilot Chat’s expanded features. The policy tightens access to certain AI tools while encouraging upgrades to the premium Copilot license tier.
Usage Restrictions and Fair-Use Limits
Although Microsoft has previously set fair-use caps on some functions, like generating images, it is now broadening those constraints to cover more Copilot Chat abilities, yet it has not revealed which functions will be limited nor the exact usage thresholds.
According to the updated policy, when a user hits the fair-use ceiling for a particular feature, the system will display an in-app alert showing the time when the feature will be usable again. The same portal that stores Microsoft 365 Message Center alerts also notes that administrators are unable to see, adjust, or bypass these limits.
Impact on Enterprise Users
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.
Nhat Bui, who serves as deputy director of engineering at Scopic Software, agreed, noting that erratic caps may interfere with workflow. He said, “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.”
Jain highlighted that moving between applications may raise wider governance issues for CIOs, because staff annoyed by the limits might adopt other AI solutions not sanctioned by their organization, thereby raising the chance of shadow AI.
Challenges for CIOs and Microsoft
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.”

Jha suggested that to counter the hidden caps, CIOs might analyze internal consumption metrics to pinpoint workers who depend heavily on Copilot Chat, grant them paid licenses first, and inform the remaining staff about the constraints of the free tier.
Jain noted that the imposed caps may pose a competitive risk for Microsoft. As more companies weigh cost certainty when selecting AI services, vendors that provide clear usage limits and pricing structures could secure an edge in the market.
The European Commission released preliminary conclusions in June 2024, concluding that Microsoft violated EU antitrust regulations by packaging Teams together with its Microsoft 365 and Office 365 productivity suites. The regulator claimed that bundling Teams provided the distribution advantage compared with rivals such as 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.
