Microsoft proposes unbundling Teams from Office in EU to boost competition

In a landmark move underscoring both regulatory pressure and the dynamic shifts underway in enterprise software, Microsoft has proposed to decouple its ubiquitous Teams collaboration platform from the Office suite, offering a cheaper, Teams-free version to European customers. This bid, detailed recently by EU antitrust authorities and swiftly cascaded through media from Reuters to The Hindu Business Line, is more than just a price shuffle—it represents a significant reckoning for Microsoft amid intensifying scrutiny over alleged anti-competitive practices. If accepted, the offer could reshape both Microsoft's European business and the broader market for collaborative productivity software.

Origins: From Slack’s Grievance to a European Commission Probe​

The saga began in earnest back in 2020, when Salesforce-owned Slack filed a formal complaint with the European Commission. At its heart was the argument that Microsoft was unfairly leveraging its dominant enterprise position, shackling Teams—a fast-growing competitor to Slack—to Office 365 and Microsoft 365 subscriptions. Critics described the maneuver as reminiscent of the historic bundling practices that embroiled Microsoft in previous EU antitrust battles over Internet Explorer and Windows Media Player.
The complaint landed at a time when pandemic-fueled remote work was turbocharging demand for digital communication tools. Microsoft’s ability to bundle Teams, then quickly growing in popularity, with Office was viewed by many market watchers as an existential threat to standalone collaboration providers. By integrating Teams as a default component—at no additional cost—Microsoft effectively created a software moat, making it harder for alternatives like Slack to gain enterprise traction.

Microsoft's New Offer: Decoupling Teams from Office​

Facing the prospect of a stifling fine and years of continued investigation, Microsoft has now tabled a compromise. The newly announced offer centers on two central commitments:

• Cheaper Office Without Teams: Microsoft will sell its Office 365 and Microsoft 365 suites in Europe at a discount when purchased without Teams. This will create a clear price distinction between the bundled and unbundled products, giving customers more explicit choice.
• Enhanced Interoperability for Rivals: Parallel to the price change, Microsoft has pledged to improve access for competitors. Specifically, rivals will gain more effective interoperability with “certain Microsoft products and services for specific functionalities,” according to the European Commission. This includes the ability for competitors to embed Microsoft’s Office Web Applications—Word, Excel, and PowerPoint—directly into their own platforms, and for these third-party offerings to feature more prominently within Microsoft’s core productivity apps.

This is not merely window dressing. The proposal aims to level the playing field by removing what critics have long alleged is an anti-competitive tie between Teams and the wider productivity suite. Importantly, customers in Europe will gain the right to extract their Teams messaging data, facilitating migration to alternative solutions should they choose.

Duration and Scope of the Offer​

According to regulators, the pricing commitment is designed to last for seven years, while interoperability improvements would extend for a full decade. Should the offer be accepted, Microsoft stated its intention to harmonize these options and prices globally—not just inside the EU, but to customers worldwide. This, if realized, would represent a watershed moment of voluntary regulatory compliance, but it remains contingent on the EC accepting the offer.
Interestingly, the Commission has now opened a feedback window, inviting input from both competitors and customers for a month before making its final decision. Salesforce and Slack, for their part, have indicated they will analyze the offer closely. Their scrutiny—and that of other market participants and public interest groups—will likely shape not only the outcome of this specific case, but also broader software bundling practices for the foreseeable future.

Technical and Business Implications​

1. Pricing and Product Clarity​

At a technical level, users and procurement managers will soon face a more granular array of options when purchasing Office in Europe. Whereas previously, Teams was bundled with most Microsoft 365 offerings by default, the new regime introduces two distinct SKUs: one with Teams, one without. This kind of unbundling is not unprecedented—the earlier EU-Microsoft showdown in the 2000s resulted in Windows N editions without integrated media functionality—but its scope in the fast-growing collaboration market is far more significant.
The principle behind the pricing strategy is clear: let customers who do not require Teams (or who prefer alternatives) pay less, thereby removing the economic disincentive to using a rival platform. For large organizations—where even small differences in license fees at scale can translate into six- or seven-figure annual variances—this is no small matter.

2. Interoperability and Data Portability​

Perhaps even more impactful than pricing is the newfound focus on interoperability. Microsoft’s commitment to allow third-parties to embed the Office Web Apps in their own platforms is a technical step forward—one that could enable competitors like Slack, Zoom, or lesser-known collaboration tools to offer a more integrated end-user experience. Instead of toggling between siloed applications, users could, hypothetically, collaborate on Word documents or PowerPoint presentations within the interface of their chosen tool.
Moreover, the guarantee that customers can extract their Teams messaging data—making it portable to rival platforms—marks an important milestone in data portability. In practice, achieving seamless migration is non-trivial: internal data formats, message threads, encryption, and metadata all pose technical hurdles. Nevertheless, the regulatory imperative is clear: customers should not become technically “locked in” to a particular vendor simply because their historical data is trapped.

3. Potential for Global Impact​

Although the immediate focus is Europe, Microsoft’s offer to extend these changes worldwide—if the EU accepts the remedy—would amplify the effects. For US companies jockeying for position against Microsoft, a level playing field in terms of bundling or interoperability would dramatically shift the competitive calculus. For customers, more clarity and more options often translates directly into tangible cost savings and flexibility.

Critical Analysis​

Strengths of Microsoft's Offer​

Regulatory Compliance and Proactivity​

Rather than dragging its feet and prolonging litigation, Microsoft’s willingness to settle pro-actively sends a signal to both regulators and customers that it is responsive to competition-related concerns. Nanna-Louise Linde, Microsoft’s Vice President for European Government Affairs, called the proposal “a clear and complete resolution to concerns raised by rivals and would give Europeans more choice.” This public commitment, if backed by genuine technical implementations, could help rebrand Microsoft as more open and competition-friendly—a sharp contrast to its historical reputation.

Encouraging a Healthier Ecosystem​

By increasing interoperability and supporting data portability, Microsoft’s remedy may help cultivate a healthier ecosystem in which innovation thrives. Rather than stifling smaller rivals via software moats, Microsoft appears to be acknowledging that modern customers prefer to mix and match best-of-breed solutions. The flexibility to deploy, say, Google Workspace for email, Slack for chat, and Office for productivity, all without artificial technical or pricing barriers, is a customer-centric approach.

Alignment with Broader Regulatory Trends​

Crucially, Microsoft’s offer aligns well with the EU Digital Markets Act (DMA) philosophy, which seeks to curb “gatekeeper” behavior in the tech sector. The DMA underscores the need for interoperability, data portability, and genuine user choice—ideals that sit at the core of Microsoft’s latest proposal.

Potential Risks and Limitations​

Implementation and Technical Hurdles​

One perennial risk is the gap between public commitments and technical reality. While Microsoft says it will make data extraction and interoperability straightforward, enterprise IT history is replete with cases where APIs are under-documented, slow, or riddled with caveats. The true test will be whether third-party vendors can, in practice, deliver smooth integration and migration experiences for end-users—or whether they hit technical dead ends.
On the interoperability side, embedding Office Web Apps in third-party platforms could, for example, be limited by performance constraints, security requirements, or feature restrictions. Vendors will closely watch rollout details and will almost certainly demand robust, well-documented APIs and support.

Pricing Complexity and Market Segmentation​

Unbundling Teams from Office is likely to satisfy some procurement concerns, but it could also add complexity to Microsoft’s sprawling product catalog. For smaller organizations, or those without dedicated IT negotiation resources, navigating the maze of SKUs, prices, options, add-ons, and support terms can become overwhelming. There’s also a risk that customers in other regions may feel shortchanged if global harmonization does not occur as promised.

Monitoring and Enforcement​

Perhaps the biggest risk lies in monitoring and enforcement. Remedies only work if they are diligently policed. The European Commission will need to ensure sustained compliance—not just for the first year, but for the full seven- and ten-year horizons defined in the proposal. History suggests this is not always straightforward: shifting product architectures, “accidental” API deprecations, or subtle nudges in the user interface can tilt the competitive playing field even when formal commitments are in place.

Market Reaction and Broader Implications​

Competitor Scrutiny​

Salesforce (Slack’s parent company) has already signaled it will “carefully scrutinise the offer.” This is likely a euphemism for a rigorous technical and legal review, probing for any loopholes or ambiguities that Microsoft could later exploit. Other rivals such as Zoom, Google, and independent EU-based SaaS vendors will also weigh in during the public comment period.

A Template for Future Tech Regulation?​

Beyond the specifics, this case may set a blueprint for resolving similar complaints against other “gatekeepers.” The EU’s ongoing investigations into Apple, Amazon, and Meta suggest that remedies around forced unbundling, improved data portability, and genuine interoperability may become the new norm. Microsoft’s willingness to deal proactively could buy it goodwill, but it may also embolden regulators to pursue similar remedies elsewhere.

Customer Benefits—and Cautious Optimism​

For enterprise customers, the immediate benefit is choice: they can pay less for Office if they do not want Teams, or choose another chat solution entirely, without sacrificing access to productivity software or critical document formats. For IT leaders ever vigilant about both costs and agility, even modest additional leverage in procurement negotiations can drive significant value.
Yet, customers would do well to remain cautiously optimistic. As the market has demonstrated, apparent compliance with regulatory diktats does not always translate into a seamless, friction-free experience—hidden technical hurdles, shifting licensing models, or subtle upselling tactics can easily undermine the spirit of reform.

The Road Ahead​

The European Commission's next step is crucial. The results of the feedback phase will be keenly watched not only by Microsoft and its direct competitors, but by every major supplier and purchaser of digital workplace technologies. If accepted, the proposal could serve both as a milestone in restoring competitive balance to enterprise collaboration and as a subtle warning to others about the costs of aggressive software bundling.
Should Microsoft implement its promises faithfully and extend its revised offering to global markets, a new equilibrium may emerge—one where interoperability is the default, data flows freely, and customers are no longer “locked in” by technical architecture or pricing gamesmanship. But this outcome depends heavily on transparent oversight, independent verification, and continued vigilance by both regulators and the market.

Conclusion​

Microsoft’s antitrust remedy in response to the EU’s probe represents both a pivotal moment for the company and a potential inflection point for the enterprise software market at large. By voluntarily offering to unbundle Teams from Office and enhance interoperability, Microsoft aims to preempt a damaging regulatory outcome—and in doing so, signals a shift toward a more open, competitive ecosystem.
For customers, the result could be lower licensing costs, greater technical flexibility, and more leverage in negotiating with vendors. For rivals, the commitment to real interoperability and data portability could finally disrupt the competitive logjam, allowing smaller innovators to compete on merit rather than inertia. But the road to realization will be measured not in headlines but in the day-to-day experience of IT departments and end users—where the true costs and benefits of Microsoft’s proposal will ultimately be tallied.
With the European Commission set to decide in the coming weeks, all eyes will be on Brussels—and on Microsoft’s willingness to turn words into action, at a time when the world is more reliant than ever on digital collaboration tools.
