Microsoft Teams was once hailed as a revolutionary tool that reshaped how organizations communicate and collaborate. Emerging in 2017 and rapidly gaining traction, Teams became the crown jewel of Microsoft’s productivity suite, often touted as the fastest-growing business application in the company’s history. However, recent developments indicate a significant shift in Microsoft’s strategy and how customers should approach this platform going forward.

This first part of the series explores the early rise of Microsoft Teams, the factors that fueled its explosive growth, and the signs that its golden era might be waning. We also examine the wider implications for users and the evolving role Teams now plays within Microsoft’s broader ecosystem.

The Meteoric Rise of Microsoft Teams

Launched officially in late 2016 and widely rolled out in 2017, Microsoft Teams was Microsoft’s answer to the rapidly growing demand for integrated, cloud-based collaboration tools. At the time, Slack dominated the market, providing real-time messaging, file sharing, and integrations that appealed to the new generation of remote and flexible work environments.

Microsoft entered this competitive arena by leveraging its vast Office 365 ecosystem, integrating Teams deeply with Outlook, SharePoint, OneDrive, and the broader Microsoft 365 platform. The promise was clear: a one-stop hub for teamwork that combined chat, video meetings, file collaboration, and workflow automation.

The impact was swift. By 2018, Teams was recognized as Microsoft’s fastest-growing business app. Adoption soared, and with the onset of the COVID-19 pandemic in early 2020, Teams became a lifeline for millions of organizations worldwide shifting to remote work almost overnight. Microsoft capitalized on this momentum by releasing frequent feature updates and improving the user experience—most without additional charges.

Why Teams Became the “Golden Child” at Microsoft

Several factors contributed to the exalted status of Teams within Microsoft:

Integration with Microsoft 365: Teams was not just a standalone app; it was woven tightly into the fabric of Microsoft’s productivity ecosystem. This integration allowed users to seamlessly move between email, document collaboration, and communication without leaving the platform.
Rapid feature development: Microsoft invested heavily in adding new functionalities, including video conferencing, breakout rooms, live captions, and extensive third-party app connectors. These enhancements often came free as part of regular updates, strengthening Teams’ value proposition.
Market demand and timing: The pandemic accelerated digital transformation, making collaboration tools essential. Teams met this need and grew exponentially in users and organizational reach.
Competitive advantage: By bundling Teams with Office 365 and Microsoft 365 subscriptions, Microsoft gained a powerful lever to compete against Slack and others, offering enterprise-grade security, compliance, and scalability.

For a time, Teams was unquestionably the “golden child” of Microsoft’s cloud portfolio—a high-growth, strategic asset fueling both user engagement and revenue growth.

Early Signs of a Shift

Despite its success, cracks began to appear by 2021. Microsoft quietly changed how it reported Teams usage, shifting from daily active users to monthly active users. This subtle adjustment raised eyebrows among analysts and customers, as it suggested growth was slowing or plateauing.

Around the same time, competition in the collaboration space intensified. Slack, now under Salesforce, pursued antitrust litigation accusing Microsoft of unfairly bundling Teams with Office products, arguing this harmed market competition. The lawsuit gained public attention and regulatory scrutiny, particularly in Europe.

Furthermore, the rapid feature expansion that characterized Teams’ early days began to slow. Users noticed that many new functionalities were either behind paywalls or introduced as premium add-ons, signaling a shift from growth-at-all-costs to revenue maximization.

The Impact of Antitrust and Regulatory Challenges

Regulators worldwide have increasingly scrutinized Microsoft’s bundling practices, particularly in Europe. In mid-2025, the European Commission released preliminary findings that Microsoft’s inclusion of Teams with its Microsoft 365 and Office 365 subscriptions constituted an illegal bundling arrangement.

In response, Microsoft offered Teams as a standalone, separately priced product for new customers. Yet, regulators have indicated that this step is insufficient, and further penalties or remedies may be forthcoming, including hefty fines that could amount to billions of dollars.

This regulatory pressure has implications beyond compliance. It influences how Microsoft packages Teams and may affect licensing models, pricing, and the overall direction of the product. Customers should anticipate changes that could impact cost structures and feature availability.

Transitioning from Growth to Monetization

When Microsoft products mature beyond their early adoption and rapid growth phase, the company typically shifts focus toward maximizing average revenue per user (ARPU). For Teams, this means a more deliberate monetization strategy.

Recent initiatives illustrate this trend clearly:

Teams Premium: Launched as a paid tier, Teams Premium offers AI-driven meeting features, enhanced security, and advanced management tools at an additional cost of around $10 per user per month.
Copilot Integration: Microsoft’s AI assistant, Copilot, is being integrated into Teams, but accessing it requires a further $30 per user per month fee.
Feature Paywalls: Capabilities that were once bundled for free are increasingly segmented into paid add-ons or premium packages.

This approach reflects a broader corporate strategy of leveraging established products to generate steady revenue, while focusing innovation and marketing on newer “golden children” in Microsoft’s portfolio, such as Copilot and other AI-powered tools.

What This Means for Organizations Using Teams

For organizations relying on Teams as a central collaboration platform, these shifts raise important questions:

Cost Management: As new features move behind paywalls, budgets for collaboration tools may need to increase to maintain or enhance capabilities.
Feature Prioritization: Businesses must assess which premium features provide genuine value versus those they can do without or replace with third-party tools.
Migration and Integration: Changes like the planned phase-out of Office 365 Connectors require organizations to plan carefully to avoid disruptions and unexpected costs.
Regulatory Impact: For customers in Europe, the antitrust case may lead to new licensing options or forced product changes, which could affect deployment strategies.

In short, Teams remains a critical tool, but its evolution demands greater vigilance and strategic planning from customers.

The Role of Teams in Microsoft’s Ecosystem

Despite these challenges, Teams is unlikely to disappear anytime soon. It remains deeply embedded in millions of organizations’ workflows and Microsoft’s cloud infrastructure.

However, its role is shifting from a relentless growth engine to a mature, revenue-generating component supporting Microsoft’s broader ambitions. New technologies like Copilot and other AI innovations are being positioned as the future’s flagship offerings.

For customers, this means balancing continued investment in Teams with exploration of alternative solutions and integrations that might better align with evolving business needs and budgets.

Navigating the Storm: Regulatory Battles and Technical Shifts Impacting Microsoft Teams

Microsoft Teams once stood unchallenged as the centerpiece of Microsoft’s collaboration and productivity efforts. However, the landscape surrounding Teams is becoming increasingly complex. Beyond the company’s evolving monetization strategy, customers now face mounting regulatory scrutiny and significant technical changes that could reshape how Teams is used and managed.

In this second part of the series, we explore the regulatory pressures confronting Microsoft, the technical implications of recent and upcoming feature retirements, and practical guidance for customers aiming to future-proof their investments in Teams.

The European Antitrust Investigation: A Turning Point

In 2025, Microsoft confronted a major challenge as the European Commission (EC) finalized its preliminary conclusion that Microsoft had engaged in illegal bundling practices by including Teams with its Microsoft 365 and Office 365 subscriptions. This ruling stemmed from a broader push by regulators to foster fair competition in cloud productivity and collaboration markets.

The EC’s position is that Microsoft’s bundling of Teams creates unfair market barriers for competitors and limits customer choice. While Microsoft responded by unbundling Teams for new customers earlier in the year—offering it as a separately priced product—regulators found this insufficient to address their concerns.

Should the EC proceed with formal charges, Microsoft could face fines up to 10 percent of its global annual revenue. Additionally, the EC may impose remedies ranging from mandated product unbundling to licensing changes that could affect pricing and availability.

This antitrust case is pivotal not only for Microsoft but also for the wider tech industry. It highlights growing regulatory vigilance over platform dominance and integrated service offerings.

Implications for Microsoft and Its Customers

From Microsoft’s perspective, these regulatory challenges create both legal and business uncertainties. The company must balance compliance with maintaining Teams’ market position and profitability. This delicate balancing act may result in altered product strategies, modified bundling policies, and potential increases in pricing or licensing complexity.

For customers, especially those in Europe but increasingly worldwide, the fallout could mean:

New Licensing Models: Customers might see Teams offered under different subscription structures or as standalone licenses with distinct pricing tiers.
Feature Availability Changes: Regulatory mandates may require Microsoft to decouple some integrated Teams features from Microsoft 365 subscriptions, forcing customers to pay separately for components once included.
Increased Costs: To maintain comprehensive functionality, organizations might need to purchase additional licenses or premium tiers.
Vendor Complexity: Customers could face more complicated procurement and contract management as Microsoft separates Teams from its traditional bundled offerings.

Understanding these potential changes early is crucial for organizations to anticipate budget adjustments and renegotiate contracts accordingly.

The Phase-Out of Office 365 Connectors: A Case Study in Transition

In parallel with regulatory pressures, Microsoft is making significant technical changes to Teams that affect day-to-day operations for many users. One prominent example is the planned retirement of Office 365 Connectors.

Office 365 Connectors allow users to integrate updates from various Microsoft and third-party services directly into Teams channels. These connectors have been a popular way to automate information flow and keep teams informed.

Microsoft announced that this feature will be phased out between August 15, 2025, and January 1, 2026, replacing it with alternatives such as Power Automate workflows, Teams apps, or Microsoft Graph API integrations.

Customer Reactions and Concerns

The announcement generated widespread criticism among Teams users. Common complaints included:

Short Notice: Many customers felt the timeline for transition was too tight to adequately plan and implement alternatives.
Insufficient Documentation: Early migration guidance and resources were perceived as lacking in detail, leaving IT teams scrambling.
Cost Implications: Microsoft’s suggested replacements, particularly Power Automate, may entail additional licensing fees, potentially increasing operational expenses.
Disruption Risks: The removal of a widely used feature raises concerns about temporary interruptions and the loss of functionality.

In response to feedback, Microsoft extended the phase-out deadline slightly and promised improved migration tools. Nonetheless, the situation exemplifies the challenges organizations face in adapting to rapid product changes.
