Microsoft is facing a mass lawsuit in the United Kingdom, alleging it overcharged nearly 60,000 British businesses for using its Windows Server software on rival cloud computing platforms provided by Amazon (company), Alphabet Inc., and Alibaba Group. The United Kingdom — Competition Appeal Tribunal in London has ruled that the case can proceed to trial, rejecting Microsoft's argument to dismiss it. The lawsuit, brought by competition lawyer Maria Luisa Stasi, claims damages of up to 2.1 billion pounds ($2.8 billion). The core of the argument is that Microsoft charges higher wholesale prices for Windows Server when used on competitor platforms compared to its own Azure service, making Azure comparatively cheaper.

This legal action comes amidst broader scrutiny of Microsoft's cloud computing practices by regulators in the United Kingdom, Europe, and the United States, with the United Kingdom — Competition and Markets Authority having previously stated that Microsoft's licensing practices reduced competition.
