Microsoft Teams Bundling Under Fire: EU Antitrust Investigation Heats Up
Slack's complaint and European regulators' probe challenge Microsoft's practice of tying Teams to Office 365
The European Commission's antitrust investigation into Microsoft's bundling of Teams with its Office 365 productivity suite represents one of the most significant competition enforcement actions in the technology sector in years. The probe, initiated following a formal complaint by Slack Technologies (now owned by Salesforce), examines whether Microsoft has leveraged its dominant position in office productivity software to unfairly suppress competition in the workplace communication and collaboration market.
Slack's complaint, filed in 2020 and escalated through subsequent regulatory proceedings, alleges that Microsoft's decision to include Teams at no additional cost within Office 365 subscriptions constituted illegal tying.
Key Takeaways
- Slack filed a formal antitrust complaint alleging Microsoft illegally tied Teams to Office 365
- Teams grew from 20 million to 320 million daily users during the bundling period
- Microsoft's partial unbundling in Europe has been criticized as insufficient to restore competitive balance
