The ACCC has initiated legal proceedings against Microsoft for allegedly misleading 2.7 million Australian customers regarding their Microsoft 365 subscriptions by failing to disclose the existence of a lower-cost "Classic" plan. The case centers on claims that Microsoft's communications suggested subscribers had to accept a price increase for the new Copilot integration or cancel their subscription, thus denying them informed decision-making. The ACCC is seeking consumer redress and penalties for the alleged conduct.
