Microsoft’s rapid ascent in the communications and productivity software market is a story deeply entwined with the spectacular rise of Teams. Once a modest chat and collaboration tool bundled within Microsoft 365, Teams morphed into a near-ubiquitous solution for enterprises and institutions across Europe and beyond, bolstered by a pandemic-fueled surge in remote and hybrid work. Yet, this meteoric growth came at a cost: mounting scrutiny from European regulators and rivals, especially over Microsoft’s decision to tightly couple Teams with its market-dominant productivity suite. Now, after years of legal maneuvering and industry drama, Microsoft and the European Commission appear poised to close this heated antitrust chapter—not with a punitive bang, but a handshake and a string of new commitments.
The roots of the dispute stretch back to 2020. Slack Technologies, then an independent workplace chat startup, filed a formal complaint to the European Commission, arguing that Microsoft’s integration of Teams into its Office 365 and Microsoft 365 suites amounted to illegal tying. Slack alleged that by bundling Teams for free with these ubiquitous productivity platforms, Microsoft was using its overwhelming dominance in productivity software as a weapon to force adoption of its nascent collaboration solution, making it difficult for rivals to compete on merit.
The complaint triggered an in-depth investigation by the European Commission, which echoed the region’s decades-long vigilance against Microsoft’s business practices. This regulatory pressure isn’t novel for the Redmond giant—Microsoft has previously faced record-breaking EU fines, most notably over its bundling of Internet Explorer and Windows Media Player with the Windows operating system. What made the Teams case unique, however, was the context: in the aftermath of COVID-19, digital collaboration became not merely a competitive space, but critical infrastructure for European governments, corporations, and educational institutions.
The core of the antitrust concern was twofold:
Yet, rather than choosing confrontation, Microsoft began seeking compromise. Throughout 2023 and into early 2024, the company repeatedly signaled its willingness to decouple Teams from its broader product bundles—echoing the sort of remedy that the European Commission has imposed in past antitrust settlements.
Initial feedback from industry figures—most notably Salesforce, which now owns Slack—has been cautious. Their legal teams are still dissecting the proposal’s fine print, signaling persistent skepticism that Microsoft will enable robust competition rather than a token gesture.
Regulators must maintain vigilance and require independent assessment to ensure Microsoft’s interoperability commitments translate into tangible, lasting benefits for rivals and consumers alike.
Thus, while regulatory intervention may level certain aspects of the playing field, the reality is that rivals still face an uphill climb. The market’s inertia, combined with Microsoft’s ability to cross-promote within its colossal ecosystem, remains a formidable, if not insurmountable, barrier to true competitive parity.
Yet, the broader industry is more circumspect. Some smaller competitors welcome the unbundling and new technical commitments as overdue; others doubt whether these steps alone will materially improve their fortunes. For many, the outcome of this case will be a blueprint—perhaps precedent—for handling platform bundling and digital ecosystems that stretch far beyond messaging tools.
Meanwhile, the European Commission is already shifting its sights to new digital frontiers, with Apple, Google, and other tech titans under parallel scrutiny for possible abuses of dominance in app store policies and online search.
The amicable resolution of the Microsoft-Teams clash suggests a maturing relationship between mega-platforms and European regulators—one focused less on retroactive punishment, and more on proactive system design. Still, each new concession by a tech giant sets precedent and expectations for the next investigation. The stakes are high: competition policy doesn’t just shape company fortunes, but defines which tools, platforms, and data controls European citizens and enterprises will rely upon.
Yet, amid this amicable finale, deeper questions linger. Will technical and pricing changes catalyze real competition, or is Microsoft’s entrenched market grip simply too strong to shake? Can voluntary commitments ever substitute for the deterrent effect of proactive enforcement and meaningful penalties? And, crucially, does this settlement signal a new regulatory era—one of negotiation rather than confrontation—or is it merely a waypoint in the long journey toward truly open digital markets?
For now, European enterprise customers have gained more choices, and rivals a glimmer of hope. The real test will play out not in press releases or regulatory filings, but in the marketplace—where integration, usability, cost, and trust will determine which collaboration tool ultimately wins out. As the ecosystem continues to evolve, the Microsoft-Teams case will remain a touchstone in the global debate over competition, innovation, and the future of work in the cloud-first era.

The Genesis of the Teams Antitrust Storm
The roots of the dispute stretch back to 2020. Slack Technologies, then an independent workplace chat startup, filed a formal complaint to the European Commission, arguing that Microsoft’s integration of Teams into its Office 365 and Microsoft 365 suites amounted to illegal tying. Slack alleged that by bundling Teams for free with these ubiquitous productivity platforms, Microsoft was using its overwhelming dominance in productivity software as a weapon to force adoption of its nascent collaboration solution, making it difficult for rivals to compete on merit.The complaint triggered an in-depth investigation by the European Commission, which echoed the region’s decades-long vigilance against Microsoft’s business practices. This regulatory pressure isn’t novel for the Redmond giant—Microsoft has previously faced record-breaking EU fines, most notably over its bundling of Internet Explorer and Windows Media Player with the Windows operating system. What made the Teams case unique, however, was the context: in the aftermath of COVID-19, digital collaboration became not merely a competitive space, but critical infrastructure for European governments, corporations, and educational institutions.
The Surge of Teams—and the Market Power Concerns
Microsoft Teams’ user numbers exploded during the pandemic. According to Microsoft’s own disclosures and industry tracking, daily active users leapt from 32 million in March 2020 to more than 270 million by early 2022. This dwarfed much of the competition, including Slack and Cisco Webex, and entrenched Teams as a default digital workspace for millions.The core of the antitrust concern was twofold:
- Bundling: Because Teams came as a default part of Microsoft 365 and Office 365 subscriptions, organizations effectively received it at no additional cost. For many IT departments—especially those already entangled in the Microsoft ecosystem—adopting a competing tool meant paying extra, or navigating complex integrations.
- Interoperability roadblocks: Rivals argued that Microsoft did not play fair with APIs or data portability, making it difficult to integrate or transfer information from Teams to other platforms.
Regulatory Response and Microsoft’s Moves
The European Commission responded promptly, seeking information from customers and competitors in a broad “request for information” process. Regulators made clear that Microsoft’s outsized influence could have a negative impact on competition and, by extension, consumer choice.Yet, rather than choosing confrontation, Microsoft began seeking compromise. Throughout 2023 and into early 2024, the company repeatedly signaled its willingness to decouple Teams from its broader product bundles—echoing the sort of remedy that the European Commission has imposed in past antitrust settlements.
Microsoft’s “Good-faith” Commitments: What’s on the Table?
Nanna-Louise Linde, vice president of European Government Affairs at Microsoft, described the ongoing negotiations with Brussels as “good-faith discussions” dedicated to fully addressing competitor concerns. Microsoft has proposed several practical commitments:- Unbundling Teams: Microsoft will now offer both Office 365 and Microsoft 365 subscriptions in the European Economic Area (EEA) with and without Teams. Customers who opt for the version without Teams will pay a lower price. This move directly responds to competitor concerns about forced adoption and economic lock-in.
- Interoperability improvements: Microsoft pledged to enhance interoperability. Specifically, Microsoft will provide publicly accessible APIs and documentation, making it easier for third-party developers and rival platforms to connect with Teams or migrate data out of it. This addresses claims that Teams’ technical structure was a barrier to fair competition.
- Data portability: By introducing mechanisms for users to transfer their data from Teams to other collaborative tools, Microsoft aims to reduce switching costs—a critical issue flagged by both the Commission and affected competitors.
Critical Assessment: Are the Remedies Enough?
The proposal to offer Teams as a standalone product in Europe and enhance interoperability sounds, on its surface, like a decisive win for fairness and choice. However, several key questions—and risks—remain:1. Pricing and True Choice
One of the linchpins of any unbundling remedy is pricing structure. While Microsoft says it will now offer lower-priced Office 365 and Microsoft 365 subscriptions sans Teams, the details matter. If the price reduction is nominal, customers may still perceive limited incentive to avoid the Teams bundle. An effective remedy should ensure the price of the “Teams-less” suite reflects the true market cost of alternative collaboration tools.Initial feedback from industry figures—most notably Salesforce, which now owns Slack—has been cautious. Their legal teams are still dissecting the proposal’s fine print, signaling persistent skepticism that Microsoft will enable robust competition rather than a token gesture.
2. Efficacy of Interoperability Efforts
The promise of improved interoperability and data portability only yields competitive gains if executed sincerely. Public APIs, clear documentation, and standardized data exchange formats can lower technical barriers, but Microsoft’s track record in this arena has been mixed. Rival developers have expressed concerns that even when APIs exist, undocumented restrictions, throttling, or subtle differences can limit real-world compatibility.Regulators must maintain vigilance and require independent assessment to ensure Microsoft’s interoperability commitments translate into tangible, lasting benefits for rivals and consumers alike.
3. Market Dynamics and Entrenched Position
Even absent forced bundling, Microsoft’s dominance in enterprise productivity software means that Teams retains a massive installed base and momentum. The company enjoys unmatched integration across its ecosystem—Windows, OneDrive, SharePoint, Outlook, and Azure—making it difficult for any upstart to lure away customers.Thus, while regulatory intervention may level certain aspects of the playing field, the reality is that rivals still face an uphill climb. The market’s inertia, combined with Microsoft’s ability to cross-promote within its colossal ecosystem, remains a formidable, if not insurmountable, barrier to true competitive parity.
4. No Fine—A Free Pass?
Unlike prior EU antitrust actions—which resulted in multibillion-euro penalties for Microsoft—this negotiation is expected to conclude with no fine. Some industry observers view this as a pragmatic move; others see it as a troubling precedent, where dominant players can escape penalties so long as they pledge future reforms. The absence of a fine reduces the immediate financial disincentive for future competition law breaches, but it could also reflect recognition by Brussels of the rapidly evolving, complex nature of the software market, and a preference for voluntary compliance over adversarial litigation.Industry and Regulatory Reaction
Salesforce, whose $27 billion bet on Slack hinged on disrupting Microsoft’s reign, was among the most vocal complainants. Their president, Sebastian Niles, asserted that even the European Commission’s willingness to settle is a tacit admission that Microsoft’s practices violated antitrust law.Yet, the broader industry is more circumspect. Some smaller competitors welcome the unbundling and new technical commitments as overdue; others doubt whether these steps alone will materially improve their fortunes. For many, the outcome of this case will be a blueprint—perhaps precedent—for handling platform bundling and digital ecosystems that stretch far beyond messaging tools.
Meanwhile, the European Commission is already shifting its sights to new digital frontiers, with Apple, Google, and other tech titans under parallel scrutiny for possible abuses of dominance in app store policies and online search.
Wider Implications for Digital Regulation
The Microsoft-Teams case is a microcosm of a broader regulatory reckoning reshaping Europe’s digital economy. The EU’s Digital Markets Act (DMA), now in force, enshrines a sweeping toolkit for curbing the power of “gatekeepers.” Under the DMA, bundling and interoperability concerns are codified, and the Commission has new powers to mandate interoperability and levy hefty fines for breaches.The amicable resolution of the Microsoft-Teams clash suggests a maturing relationship between mega-platforms and European regulators—one focused less on retroactive punishment, and more on proactive system design. Still, each new concession by a tech giant sets precedent and expectations for the next investigation. The stakes are high: competition policy doesn’t just shape company fortunes, but defines which tools, platforms, and data controls European citizens and enterprises will rely upon.
The View Ahead: Will Competition Truly Flourish?
Looking to the future, several factors will determine whether the settlement prompts meaningful market change:- Execution of technical commitments: It is vital that Microsoft’s APIs, documentations, and data transfer pathways remain open, up to date, and fairly governed. Ongoing independent audits or regulatory monitoring may be needed to prevent backsliding.
- Market responsiveness: Competitors must seize the opportunity (however imperfect) to innovate and differentiate. Success depends not just on regulation, but on their ability to offer enticing, integrated experiences.
- Customer awareness: IT buyers in Europe must be better informed of their expanded choices and the true cost—financial and technical—of migrating away from Teams.
- Regulatory agility: As technology and business models keep evolving, so must regulatory approaches. Lessons learned here will be critical as new categories (AI, cloud platforms, edge computing) emerge.
Conclusion
The likely conclusion of the EU’s antitrust investigation into Microsoft Teams marks a rare moment of détente in the protracted battle between Big Tech and European regulators. By decoupling Teams from Office and Microsoft 365, offering lower-priced alternatives, and pledging interoperability, Microsoft temporarily sidesteps another blockbuster fine and signals a willingness to adapt—albeit on terms it helped shape.Yet, amid this amicable finale, deeper questions linger. Will technical and pricing changes catalyze real competition, or is Microsoft’s entrenched market grip simply too strong to shake? Can voluntary commitments ever substitute for the deterrent effect of proactive enforcement and meaningful penalties? And, crucially, does this settlement signal a new regulatory era—one of negotiation rather than confrontation—or is it merely a waypoint in the long journey toward truly open digital markets?
For now, European enterprise customers have gained more choices, and rivals a glimmer of hope. The real test will play out not in press releases or regulatory filings, but in the marketplace—where integration, usability, cost, and trust will determine which collaboration tool ultimately wins out. As the ecosystem continues to evolve, the Microsoft-Teams case will remain a touchstone in the global debate over competition, innovation, and the future of work in the cloud-first era.
