The European Commission’s recent scrutiny of Microsoft’s bundling of Teams with its Office 365 and Microsoft 365 suites marks a pivotal moment in the ongoing debate over anticompetitive behavior in the technology sector. This case, which has its roots in formal investigations opened in July 2023 and subsequent complaints from competitors like Slack Technologies and alfaview GmbH, raises critical questions about market dominance, interoperability, and the responsibility of global platform providers in shaping fair digital marketplaces.
At the core of the Commission’s inquiry lies the question of whether Microsoft, by tying Teams to its dominant productivity applications, has restricted competition and unfairly cemented Teams’ position in the burgeoning market for unified communication and collaboration tools. Microsoft Teams, launched as a direct competitor to platforms like Slack and Zoom, integrates messaging, video, calling, and document sharing—features that have become indispensable for businesses shifting toward hybrid or fully remote work models.
The Commission’s investigation, formalized under case numbers AT.40721 and AT.40873, cites potential violations of Article 102 of the Treaty on the Functioning of the European Union (TFEU) and Article 54 of the Agreement on the European Economic Area (EEA). Both prohibit abuse of a dominant position that might restrict competition or affect trade within the EU. Specifically, Microsoft’s default inclusion of Teams in its Office and Microsoft 365 suites since at least April 2019 raised concerns that competitors faced undue barriers to entry—notably, restricted interoperability and a lack of user choice.
The Commission’s intervention underscores the proactive role of European regulators in policing digital market dynamics. Rather than waiting for harm to consumers or irreversible concentration of market power, the Commission has acted preemptively, based on clear indicia of harm: customer lock-in, reduced innovation, and diminished interoperability. By requiring a market test—inviting feedback from businesses, developers, and civil society—the process gains transparency and participatory legitimacy.
2. Structural and Behavioral Remedies
Microsoft’s commitment package is notable for blending both structural change (unbundling) and behavioral constraints (interoperability, non-discriminatory pricing). This two-pronged approach seeks not only to undo the effects of past tying but also to establish conditions for robust, ongoing competition.
3. Data Portability as a User Right
Enshrining data portability as an enforceable obligation is a concrete gain for business customers. It paves the way for easier migration between platforms, lowering the risk of vendor lock-in that has historically characterized enterprise productivity software.
4. Global Ramifications
By indicating willingness to harmonize worldwide offers to match EU obligations, Microsoft signals the global “Brussels effect”: EU regulation often sets de facto benchmarks for international practice. For multinational enterprises and SaaS providers, this could have both compliance and strategic implications far beyond the immediate region.
Remedy design is only as meaningful as its enforcement. While the appointment of an independent monitoring trustee and provisions for fast-track arbitration are positives, the devil will lie in the details—especially regarding technical interoperability and the practicalities of data extraction. Past experience with big tech commitments in the EU has sometimes revealed loopholes or “checkbox compliance” rather than substantive change.
2. Duration and Adequacy of Commitments
With commitments lasting seven to ten years, there is a risk that rapid technological shifts might outpace the remedies. For instance, if generative AI, automation, or modular workplace tools drastically alter the collaboration software landscape, today’s interoperability standards may seem dated. Flexibility, regular review, and adaptive regulatory oversight will be necessary to ensure that the remedies continue to serve the competitive purpose.
3. Market Power and Ecosystem Effects
Even with unbundling, Microsoft’s entrenched position due to the sheer ubiquity of Office and Microsoft 365 may grant Teams a durable advantage—through network effects, pre-existing customer relationships, and integration with broader Microsoft cloud offerings. The question of whether the unbundled versions will be actively promoted to customers—and not relegated to hidden configuration pages—remains open. Competitors will watch not just technical compliance, but also the commercial practices accompanying the new product lineup.
4. Unintended Consequences
While facilitating switching and interoperability generally help competition, there is also potential for complexity, confusion, or increased administrative overhead for buyers. Organizations might struggle to evaluate the relative costs and benefits of bundled and unbundled suites, especially if the pricing differentials are modest or if feature gaps persist.
Enterprise customers, in particular, have a vested interest in ensuring a level playing field. For many, the possibility of unbundled purchasing, guaranteed interoperability, and safe data migration may offer newfound leverage in SaaS sourcing negotiations. However, the true measure of impact will be in the choices exercised by actual organizational buyers over the coming years.
If global convergence occurs, enterprises around the world may see heightened software choice, increased bargaining power, and a renewed focus on interoperability. On the supplier side, both established competitors and innovative startups could find more fertile ground for differentiated offerings and integration partnerships.
The story resonates, too, with parallel efforts in digital markets act (DMA) enforcement, data portability for users (as seen in GDPR and evolving US state privacy laws), and broader debates about self-preferencing and platform neutrality.
Several possible scenarios could unfold:
If enforced robustly and in good faith, the commitments offered in this case have the potential to inject greater dynamism into the enterprise communications market, empower customers with real options, and anchor data portability as a user right. At the same time, the episode highlights the ongoing challenges facing regulators as they grapple with fast-moving markets, powerful incumbents, and the perennial risk of remedies becoming obsolete before they are fully realized.
For Microsoft, competitors, and customers alike, the next chapter will unfold not in the pages of official decrees, but in the day-to-day decisions of buyers, the evolution of enterprise platforms, and the continuing dialogue between innovation and regulation. The lessons learned here—about vigilance, transparency, and the necessity of keeping markets open—will echo far beyond the confines of the EU, influencing digital competition policy for years to come.

The European Commission’s Investigation: Context and Concerns
At the core of the Commission’s inquiry lies the question of whether Microsoft, by tying Teams to its dominant productivity applications, has restricted competition and unfairly cemented Teams’ position in the burgeoning market for unified communication and collaboration tools. Microsoft Teams, launched as a direct competitor to platforms like Slack and Zoom, integrates messaging, video, calling, and document sharing—features that have become indispensable for businesses shifting toward hybrid or fully remote work models.The Commission’s investigation, formalized under case numbers AT.40721 and AT.40873, cites potential violations of Article 102 of the Treaty on the Functioning of the European Union (TFEU) and Article 54 of the Agreement on the European Economic Area (EEA). Both prohibit abuse of a dominant position that might restrict competition or affect trade within the EU. Specifically, Microsoft’s default inclusion of Teams in its Office and Microsoft 365 suites since at least April 2019 raised concerns that competitors faced undue barriers to entry—notably, restricted interoperability and a lack of user choice.
Microsoft’s Proposed Commitments: Substance and Implications
Responding to these concerns, Microsoft has offered several commitments designed to alleviate the competitive imbalance and restore choice for enterprise customers across the European Economic Area (EEA):- Decoupling Teams from Office/Microsoft 365: Microsoft pledges to offer versions of its business productivity suites without Teams, at a reduced price, to customers in the EEA. Crucially, this is not merely a pricing adjustment; organizations can move away from bundled Teams—even within existing contracts—without penalty or administrative roadblocks. This element responds directly to allegations that Microsoft’s past changes, announced after the formal investigation opened, were insufficient in scope or clarity.
- Price Parity Commitments: The company commits to refraining from offering higher discounts on Teams or on bundled suites relative to the unbundled versions. This is a calculated move to forestall indirect forms of tying, where preferential pricing could still tip the competitive scales.
- Enhanced Interoperability: In a direct nod to the needs of Teams competitors, Microsoft commits to providing programmatic access and technical interoperability with key Office applications, permitting third parties to embed Office web apps (Word, Excel, PowerPoint) in their own offerings. Furthermore, third-party solutions would be eligible for prominent integration within Microsoft’s core productivity stack.
- Data Portability: Perhaps most significantly for business users seeking agility, Microsoft commits to allowing customers to extract Teams messaging data, facilitating migration or parallel adoption of competing solutions. This addresses both “lock-in” concerns and broader trends favoring user data sovereignty.
- Global Application: While the commitments are drafted for the EEA market, Microsoft has indicated it will align its worldwide offers and pricing accordingly—potentially reflecting the EU’s growing influence on setting global regulatory precedents in digital markets.
- Duration and Enforcement: The commitments would remain in force for seven years, with interoperability and data portability obligations extending to ten years. Compliance will be reviewed by an independent monitoring trustee, and disputes subject to accelerated arbitration.

Perspectives from Competitors and the Broader Market
The case originated via formal complaints from Slack Technologies (now part of Salesforce) and alfaview GmbH, both of which allege that Microsoft’s bundling practices have made it extremely difficult for alternative collaboration platforms to gain traction in enterprise settings. Their grievances center not only on technical integration but also on procurement inertia: when Teams is “free” or default, IT departments have little incentive to trial or adopt substitutes. While these commitments appear to address many of their key demands, their adequacy will ultimately depend on continued vigilance during the market test period and beyond.Enterprise customers, in particular, have a vested interest in ensuring a level playing field. For many, the possibility of unbundled purchasing, guaranteed interoperability, and safe data migration may offer newfound leverage in SaaS sourcing negotiations. However, the true measure of impact will be in the choices exercised by actual organizational buyers over the coming years.
Broader Antitrust and Regulatory Framework
The European Commission’s approach in this case draws heavily from a robust legal framework:- Article 102 TFEU and Regulation 1/2003: These underpin the Commission’s authority to investigate and remediate abuses of dominance. Importantly, Regulation 1/2003 allows for the imposition of binding commitments in lieu of formal infringement findings—often enabling faster, more flexible market correction than protracted litigation.
- Market Test and Third-Party Feedback: Before finalizing any binding decision, the Commission now routinely invites public comments—a reflection of both procedural fairness and the pragmatic need to assess real-world efficacy.
- Sanctions for Non-Compliance: If Microsoft (or any similar respondent) failed to honor these commitments, the Commission retains the power to levy fines up to 10% of global turnover, a penalty severe enough to deter casual disregard.
The Global Stakes: What Happens if the EU Model Spreads?
Microsoft’s decision to consider a worldwide alignment of its offers raises the prospect of a global recalibration in how SaaS giants approach product bundling. This is especially significant as regulators in the United States, United Kingdom, Australia, and elsewhere have begun their own investigations—often inspired, in part, by EU precedents.If global convergence occurs, enterprises around the world may see heightened software choice, increased bargaining power, and a renewed focus on interoperability. On the supplier side, both established competitors and innovative startups could find more fertile ground for differentiated offerings and integration partnerships.
The story resonates, too, with parallel efforts in digital markets act (DMA) enforcement, data portability for users (as seen in GDPR and evolving US state privacy laws), and broader debates about self-preferencing and platform neutrality.
Looking Ahead: The Market Test, Industry Feedback, and Future Scenarios
As of now, the Commission has opened the floor to industry feedback—a market test period during which third parties, industry groups, and even end users can voice their approval, concerns, or suggestions regarding Microsoft’s commitments. This participatory phase is likely to produce a wealth of input on everything from technical integration standards to commercial practices.Several possible scenarios could unfold:
- Positive Market Test and Binding Decision: Should the feedback indicate the commitments are sufficient and workable, the Commission will formalize them without a formal finding of infringement—a pragmatic outcome that offers immediate relief and regulatory certainty.
- Negative or Mixed Feedback: If, however, significant third-party concerns remain, the Commission has latitude to demand further refinements or even proceed to a formal infringement finding—potentially leading to harsher remedies.
- Industry Ripple Effects: Whatever the outcome, this case is poised to reverberate across the enterprise SaaS landscape, as both vendors and buyers recalibrate strategies in light of shifting regulatory expectations.
Conclusion: A Milestone in Platform Governance and Digital Competition
The European Commission’s handling of Microsoft’s Teams bundling practices is, by any measure, a watershed moment in tech regulation—one that balances structural remedies, market realities, and the fundamental principle that dominant platforms must not entrench their market positions at the expense of innovation and choice.If enforced robustly and in good faith, the commitments offered in this case have the potential to inject greater dynamism into the enterprise communications market, empower customers with real options, and anchor data portability as a user right. At the same time, the episode highlights the ongoing challenges facing regulators as they grapple with fast-moving markets, powerful incumbents, and the perennial risk of remedies becoming obsolete before they are fully realized.
For Microsoft, competitors, and customers alike, the next chapter will unfold not in the pages of official decrees, but in the day-to-day decisions of buyers, the evolution of enterprise platforms, and the continuing dialogue between innovation and regulation. The lessons learned here—about vigilance, transparency, and the necessity of keeping markets open—will echo far beyond the confines of the EU, influencing digital competition policy for years to come.
