CMA probes Microsoft 365 pricing

The UK's United Kingdom — Competition and Markets Authority (CMA) announced on July 29, 2026, that it would investigate Microsoft over whether it misled personal and family customers when marketing subscription plans for Microsoft. The probe focuses on Microsoft's addition of its AI assistant Copilot to subscriptions, where customers were initially offered Copilot at no extra cost but later faced higher-priced renewals. The CMA stated it will examine whether customers were given key information about the plans and cost differences. Microsoft said it is reviewing the claims and remains committed to working constructively with the regulator. The CMA also noted that authorities in Australia and Italy are conducting similar investigations into Microsoft's renewal information practices. This probe adds to existing global competition investigations targeting Microsoft's business software, cloud computing, and AI partnerships.
