Microsoft ACCC Lawsuit Over Microsoft 365 Price Increases in Australia

The Australian Competition and Consumer Commission (ACCC) has initiated legal proceedings against Microsoft Australia and its US parent company, alleging they misled approximately 2.7 million Australian consumers regarding Microsoft 365 subscription options and price increases. This action stems from Microsoft’s integration of its AI assistant, Copilot, into its Microsoft 365 Personal and Family plans, which led to significant price hikes and, according to the ACCC, a failure to adequately disclose alternative, lower-cost options. The lawsuit centres on communications surrounding these changes, which the ACCC claims were misleading or deceptive, potentially causing economic harm to a vast number of Australian subscribers.

The core of the ACCC’s case revolves around Microsoft’s communication strategy when introducing Copilot and associated price adjustments. It is alleged that Microsoft informed auto-renewing subscribers that to maintain their subscription, they had to accept the Copilot integration and pay a higher price, or cancel their subscription altogether. This narrative, conveyed through emails and a blog post, allegedly omitted a crucial detail: the continued availability of “Classic” plans. These Classic plans offered the same features as the previous subscriptions but without the Copilot AI integration, at the original, lower price point. The ACCC contends that this omission was deliberate, designed to steer consumers towards the more expensive plans and increase revenue.

The ACCC’s Allegations of Misleading Conduct

The Australian Competition and Consumer Commission’s lawsuit details specific allegations of misleading conduct by Microsoft. Central to these claims is the assertion that Microsoft deliberately concealed the existence of the “Classic” Microsoft 365 Personal and Family plans. These plans allowed subscribers to retain their existing features without the newly integrated Copilot AI at the previous, lower price.

The ACCC asserts that Microsoft’s communications, including two emails and a blog post sent to auto-renewing subscribers around October 2024, failed to mention these Classic plans. Instead, these communications allegedly presented consumers with a binary choice: either accept the Copilot integration and the resultant price increase, or cancel their subscription entirely. This created a false impression that no other options were available, thereby denying consumers the opportunity to make a fully informed decision.

The regulator further alleges that the only way for subscribers to discover the existence of the Classic plans was to initiate the process of cancelling their subscription. It was only after a customer had navigated to the subscription cancellation section of their Microsoft account and selected to cancel that the option to move to a Classic plan would appear on a subsequent page. This tactic, the ACCC argues, effectively hid the more affordable alternative and pressured consumers into accepting the more expensive, AI-integrated plans.

Price Increases and the Copilot Integration

The ACCC’s proceedings highlight the significant price adjustments that accompanied the integration of Copilot into Microsoft 365 Personal and Family plans. Following this integration, which began on October 31, 2024, the annual subscription price for the Microsoft 365 Personal plan saw a substantial increase of 45 percent, rising from AUD $109 to AUD $159. Similarly, the annual subscription price for the Microsoft 365 Family plan increased by 29 percent, from AUD $139 to AUD $179.

These price hikes were communicated to subscribers shortly before their renewal dates. For example, one consumer received an email on January 9, 2025, informing them of the AI feature addition and the price increase from $109 to $159, effective April 19, 2025. A subsequent email, sent just seven days before the renewal, reiterated the new payment amount of $159.00.

The ACCC is concerned that these communications, by presenting only the option to accept the higher price with Copilot or cancel, may have caused economic harm to approximately 2.7 million Australian consumers. Many of these individuals may have opted for the more expensive plan simply because they were unaware of the less costly Classic alternative.

The “Classic” Plan: An Undisclosed Alternative

The existence of a “Classic” version of Microsoft 365 Personal and Family plans is at the heart of the ACCC’s legal action. This “Classic” option allowed subscribers to continue using their existing Microsoft 365 features without the newly integrated Copilot AI, and crucially, at their previous, lower subscription price. The ACCC alleges that Microsoft deliberately omitted any mention of these Classic plans in its direct communications to customers.

This deliberate omission meant that subscribers were not made aware of the continued availability of a functionally equivalent, yet cheaper, subscription. The ACCC’s investigation, which drew on numerous consumer reports and online discussions, confirmed that the Classic plan was only discoverable by customers who actively initiated the cancellation process for their subscription. This hidden option was not featured in the emails or blog posts informing customers of the price changes.

The ACCC’s Chair, Gina Cass-Gottlieb, stated that the commission would allege in court that Microsoft “deliberately omitted reference to the Classic plans in its communications and concealed their existence until after subscribers initiated the cancellation process to increase the number of consumers on more expensive Copilot-integrated plans.” This strategy, the ACCC contends, aimed to maximise uptake of the higher-priced, AI-enhanced subscriptions.

ACCC’s Legal Aims and Potential Penalties

The Australian Competition and Consumer Commission is seeking several remedies from the Federal Court in its lawsuit against Microsoft. These include penalties, injunctions, declarations, and consumer redress for affected Australian customers. The ACCC aims to hold Microsoft accountable for alleged breaches of the Australian Consumer Law, specifically sections related to misleading or deceptive conduct and false or misleading representations about goods and services.

While the exact penalty amount is yet to be determined by the court, under Australian consumer law, the maximum penalty for each breach can be substantial. It is the greater of AUD $50 million, three times the total benefit obtained from the conduct, or, if the total benefit cannot be determined, 30 percent of the corporation’s adjusted turnover during the infringing period. This significant potential penalty underscores the seriousness with which the ACCC views the alleged conduct.

The regulator argues that consumers who were unaware of the Classic plan option may have suffered financial harm due to automatic renewals at higher prices. The ACCC’s action seeks to provide compensation for this economic harm and deter Microsoft, and other technology companies, from engaging in similar practices in the future. The case serves as a crucial test for transparency and fair dealing in the digital economy.

Microsoft’s Response and Refund Offer

In response to the ACCC’s legal action and growing scrutiny, Microsoft has issued an apology to its Australian customers. The company acknowledged that it “fell short of our standards” and could have communicated the pricing changes more clearly when they were introduced in October 2024. Microsoft stated that it introduced AI capabilities into its Microsoft 365 Personal and Family subscriptions in response to customer demand for advanced AI tools.

Furthermore, Microsoft announced it would offer refunds to eligible Australian customers who switch back to their original, lower-cost “Classic” plans from the AI-enabled Microsoft 365 Personal and Family plans. This offer is contingent on customers opting to switch before the end of 2025. The refunds would cover the difference in price paid since the introduction of the higher-priced plans. This move comes as a direct response to the legal proceedings initiated by the ACCC, which alleged that Microsoft had misled consumers by concealing cheaper subscription alternatives.

While Microsoft’s apology and refund offer represent a significant step, the ACCC has emphasized that this is not a settlement of the case. The regulator continues to seek penalties, injunctions, and other remedies in the Federal Court, indicating that the legal proceedings remain ongoing. The ACCC welcomed Microsoft’s move but stressed that the refund offer does not conclude the court case, which will proceed to determine potential penalties for the alleged breaches of Australian consumer law.

Broader Implications for Consumers and Businesses

The Microsoft ACCC lawsuit has significant implications beyond the immediate parties involved, highlighting broader issues of transparency, consumer choice, and the practices of large technology firms. The case underscores the increasing regulatory focus on how companies, particularly those with substantial market power, communicate pricing and product changes to consumers, especially when integrating new technologies like AI.

For consumers, this lawsuit serves as a reminder to critically examine subscription renewal notices and communications from service providers. It emphasizes the importance of understanding all available options, even when presented with seemingly straightforward choices between acceptance and cancellation. The case also highlights the potential for “dark patterns”—design choices intended to subtly influence user behaviour—to mislead consumers, a practice the ACCC is increasingly scrutinizing.

For businesses, the case reinforces the need for clear, accurate, and comprehensive communication regarding pricing, product features, and available alternatives. Failing to disclose material information, even if technically available through a complex process, can lead to significant legal and financial repercussions. This situation prompts businesses to review their customer communication strategies and ensure they align with consumer protection laws, fostering trust and transparency in their dealings.

The Role of Consumer Reports and Online Communities

The Australian Competition and Consumer Commission’s investigation into Microsoft’s pricing practices was significantly informed by consumer reports and discussions on online platforms. The regulator received a substantial number of reports from consumers detailing their experiences and concerns regarding the Microsoft 365 price increases and the perceived lack of clear options. These firsthand accounts were crucial in alerting the ACCC to the alleged conduct.

Online forums, such as Reddit, played a role in aggregating consumer feedback and bringing attention to the issue. The discussions within these communities often highlighted the confusion and frustration experienced by users who felt they were not given a fair choice or were unaware of the “Classic” plan. This collective feedback provided the ACCC with critical evidence to support its claims of misleading conduct and the potential for widespread consumer harm.

The ACCC’s reliance on consumer-generated information underscores the importance of consumer advocacy and the power of collective voices in holding large corporations accountable. It demonstrates that individual experiences, when shared and amplified, can trigger significant regulatory scrutiny and legal action, ultimately contributing to fairer market practices.

Future Regulatory Trends and “Dark Patterns”

The ACCC’s action against Microsoft signals a growing trend in regulatory bodies worldwide to address manipulative online practices, often referred to as “dark patterns.” These are design techniques used in user interfaces that trick or coerce users into making decisions they might not otherwise make, such as making it difficult to cancel subscriptions or understand pricing structures. The “Classic” plan’s hidden availability in the Microsoft case is seen as a potential example of such a pattern.

While “dark patterns” may not always be explicitly prohibited under current consumer laws, regulators like the ACCC are actively exploring how existing legislation, such as the Australian Consumer Law, can be applied to these practices. The ACCC’s focus on transparency and the clarity of information provided to consumers is a key element in its ongoing efforts to ensure fair competition and protect consumers in the digital marketplace.

This case, along with other regulatory actions, suggests a future where businesses will face increased scrutiny regarding the design of their online interfaces and the clarity of their communications. The emphasis will likely be on ensuring that consumers have genuine choice and are not subtly steered towards more expensive or unwanted products and services through deceptive design or information practices.

Microsoft’s Pricing Strategies and Australian Market

Microsoft has previously implemented price adjustments in Australia, including aligning global prices with US dollar rates. In 2022, for instance, a price increase of approximately 9% was applied to licenses like Microsoft 365 Business Premium and Enterprise by September 2023, as part of a global pricing strategy. More recently, in April 2025, Microsoft updated its billing for annual subscriptions, introducing a 5% price increase for businesses on annual plans with monthly payments. This strategy aims for consistent pricing worldwide but can lead to increased costs for Australian consumers and businesses, depending on currency fluctuations and local market conditions.

The ACCC’s current lawsuit, however, focuses specifically on the alleged misleading communication surrounding the integration of Copilot and the availability of alternative plans, rather than a general price increase. While Microsoft is free to adjust prices, the regulator’s concern lies in the alleged lack of transparency and the potential for consumers to be misled into paying more without being fully aware of their options. This distinction is crucial in understanding the ACCC’s legal stance.

The trial of Microsoft 365 price hikes in Australia and other Asia-Pacific countries before a global rollout in 2025 also placed Australian customers at a potential disadvantage, according to some reports. This suggests a pattern where Australian consumers may be among the first to experience pricing changes, making clear communication and disclosure even more critical.

The Importance of Informed Consumer Choice

A fundamental principle underlying consumer protection law is the right of consumers to make informed choices. The ACCC’s case against Microsoft hinges on the allegation that this right was compromised. By allegedly concealing the existence of the Classic plans, Microsoft is accused of preventing approximately 2.7 million Australian consumers from making a fully informed decision about their Microsoft 365 subscriptions.

The ACCC emphasizes that while Microsoft is within its rights to introduce new features, increase prices, or offer different plans, the method of communication is paramount. The regulator’s concern is not with the price increase itself, but with the alleged deception employed in presenting the options. The ACCC believes that many consumers would have opted for the Classic plan had they been fully aware of its availability and the associated cost savings.

This focus on informed choice has significant implications for all businesses. It underscores the responsibility to provide clear, accurate, and complete information about products and services, especially when changes are made that affect pricing or features. Transparency is not merely a best practice; it is a legal obligation that, when breached, can lead to substantial penalties and reputational damage.

ACCC’s Enforcement Priorities and Future Outlook

The ACCC has outlined its compliance and enforcement priorities for the upcoming years, with a significant focus on digital markets, manipulative online practices, and misleading pricing. The lawsuit against Microsoft aligns with these broader priorities, particularly concerning subscription traps and “dark patterns” that undermine consumer choice. The ACCC’s agenda reflects persistent consumer complaints about cost-of-living pressures and a desire to restore trust in digital markets.

Key areas of focus for the ACCC include ensuring clear and accurate pricing information in essential services, retail, and digital marketplaces. The regulator aims to address anti-competitive conduct and protect consumers from deceptive practices that limit their ability to make informed decisions. The emphasis on transparency and fair competition is expected to continue shaping the ACCC’s enforcement actions.

The ongoing legal action against Microsoft serves as a strong signal to other technology companies operating in Australia. It highlights the ACCC’s commitment to investigating and prosecuting cases where consumers are allegedly misled, particularly concerning pricing and subscription models. Businesses should anticipate increased scrutiny of their communication strategies and pricing disclosures in the digital space.
