UK, Australia, and Italy open probes into Microsoft’s Microsoft 365 and Copilot-related changes

Microsoft is facing consumer-focused regulatory investigations in the UK, Australia and Italy tied to recent changes affecting Microsoft 365 subscribers and the integration of Copilot features, according to a report published by Yahoo Finance on Aug. 1.

The article says the investigations center on Microsoft 365 subscription changes and on how Copilot capabilities are being introduced to consumers within the productivity suite. The regulators’ central question, as described in the report, is whether these changes are handled in a way that meets consumer-protection requirements.

While the report identifies the jurisdictions, it does not, in the information provided here, specify the legal theories regulators are using, the precise product adjustments under review, or the timelines and milestones for each investigation.

For Microsoft, the matter touches on a broader issue that has moved to the forefront in software and AI services: how subscription software updates, feature rollouts, and AI add-ons are communicated to users, especially when functionality, pricing, or user experience may change over time.

Microsoft’s Copilot offerings are designed to add AI-driven assistance inside familiar Microsoft applications and workflows. In consumer terms, that can mean new or expanded capabilities appearing in Microsoft 365 experiences, with users expecting consistent behavior and clear terms about what is included.

The probes also highlight scrutiny of “change management” in subscription products. Consumers generally rely on published plans, included features, and advertised behavior to decide whether to subscribe or remain subscribed. When software is updated frequently, regulators can focus on disclosure quality, consent mechanics, and whether changes materially affect the service the customer believes they are buying.

In a situation like this, what Microsoft has (and has not) disclosed publicly matters. In the materials available for this story, there is no indication of Microsoft’s response, whether Microsoft has agreed to any remedial steps, or whether it expects the investigations to be resolved quickly or through negotiations rather than enforcement actions.

Looking ahead, investors and customers will likely watch for any regulator statements that spell out the exact Microsoft 365 modifications under review, any required disclosures or user-notification practices, and whether regulators move from inquiry to formal enforcement. Microsoft could also be expected to clarify how Copilot features are licensed, presented, and billed for subscribers if regulators argue that consumers were not adequately informed.
