UK regulator investigates whether Microsoft misled personal and family customers

Microsoft 365 Subscription Probe and Customer Impact

Background of the Investigation

LONDON, July 29 (Reuters) - Britain's antitrust regulator said it would investigate Microsoft over whether it misled personal and family customers when marketing subscription plans for its ever-popular Microsoft 365 product, resulting in them overpaying.

Focus on Copilot AI Assistant Addition

The Competition and Markets Authority said on Wednesday the probe would examine Microsoft's addition of its AI assistant Copilot to Microsoft 365 subscriptions. Personal and family customers were initially offered Copilot at no extra cost, but some later faced higher-priced subscriptions when renewing.

Key Information Disclosure

"The investigation will examine whether customers were given key information about the plans and the difference in cost to understand the options available to them before making a decision," the CMA said in a statement.

CMA’s Position on AI Adoption and Transparency

The CMA said while it was supportive of AI adoption across the country, customers always needed clear and timely information.

International Regulatory Actions
