Sources: next week, the European Commission plans to open an investigation into Microsoft for bundling Teams with Office, after deeming concessions insufficient
Investigation will centre on claims US tech giant is unfairly linking its videoconferencing app with popular software
Context & Ripple Effects
This scoop is the opening move in a case that has been building since Slack's 2020 complaint to EU antitrust regulators about Teams being tied to Office. The Commission had already signaled intent, and per sources here it judged Microsoft's offered concessions insufficient to head off a formal probe.
The related coverage confirms the arc played out: the investigation opened within weeks as the first EU antitrust investigation into a major tech company in more than a decade, and by mid-2024 the Commission moved to preliminary findings charging Microsoft with giving Teams an undue advantage despite the concessions.
First-order effects
- Microsoft now faces a formal dominant-position investigation centered on tying Teams to Office, with its concession package rejected as inadequate — meaning the unbundling question moves from negotiation to enforcement.
- Teams rivals, most prominently complainant Slack, gain an official regulatory vehicle for their bundling grievances rather than relying on market pressure alone.
Second-order effects
- If the Commission forces separation of Teams from Office pricing, enterprise software vendors competing on suites-plus-collaboration bundles face pressure to unbundle their own pricing structures in Europe.
- Microsoft's concessions being deemed insufficient sets a bar for future remedy offers: other investigated firms learn partial commitments may not stop charges from being issued.
Third-order effects
- As the first such EU investigation in over a decade, the case marks a revival of structural antitrust enforcement against US platform bundling, with remedies likely to shape how suite vendors package collaboration tools across the industry.
- A pattern of concessions failing to preempt charges points toward regulators favoring mandated separation over negotiated fixes as the default outcome for tying cases.
The trend: European regulators are reasserting antitrust enforcement against US tech giants' product-bundling practices, with the Teams-Office case as the reopening data point.
