UK REGULATOR LAUNCHES FORMAL MICROSOFT OFFICE PROBE

The Competition and Markets Authority (CMA) is investigating Microsoft's practice of packaging Word, Excel, Teams, and its AI assistant Copilot together in Office bundles. The regulator is assessing whether this bundling strategy gives Microsoft unfair competitive advantages and restricts consumer choice. The investigation focuses on whether competitors face barriers to entry when Microsoft ties multiple productivity and communication tools into single offerings. What triggered the probe The CMA's formal inquiry follows preliminary concerns about Microsoft's market practices. The regulator has been examining competition issues in cloud services and productivity software markets, where Microsoft holds significant market share through its Office 365 (now Microsoft 365) subscription services. The bundling strategy allows Microsoft to promote Teams—its workplace communication platform—alongside universally-used tools like Word and Excel. This integration makes it harder for rival communication platforms like Slack to compete for users who already have Microsoft's suite installed. Scope of investigation The CMA will examine: - Whether bundling reduces competition in productivity software - Impact on alternative providers' ability to compete - Consumer choice and switching costs - Copilot's integration with established Office applications Microsoft faces similar scrutiny globally. The European Commission has previously investigated the company's practices, and regulators worldwide increasingly scrutinize how tech giants bundle products across their ecosystems. Next steps The investigation is now in its formal phase. Microsoft will have opportunities to respond to the CMA's findings. The process typically takes several months, with the regulator publishing provisional findings before issuing final determinations. A formal investigation doesn't guarantee regulatory action, but it signals the CMA's serious concerns about Microsoft's competitive practices in the UK market.
