Microsoft’s latest regulatory saga in the European Union has unfolded with all the drama of a high-stakes legal thriller—except the suspense ended not with resolution but with regulatory theater. On July 28, 2025, the European Data Protection Supervisor (EDPS) closed a four-year investigation into the European Commission’s use of Microsoft 365, declaring compliance victory just weeks after Microsoft’s own executives admitted, under oath, that they cannot guarantee European data will be shielded from US government access. The case shines a harsh spotlight on the widening rift between regulatory satisfaction and the stark realities of data sovereignty in the cloud era.
Data sovereignty and privacy have become defining issues in the European Union’s tech regulation, especially as American cloud giants tighten their grip on digital infrastructure. For years, EU institutions have battled to ensure that the rights guaranteed by the General Data Protection Regulation (GDPR) are meaningful in practice—not just on paper.
The stakes were raised when the US enacted the CLOUD Act, granting American authorities extraterritorial power to compel data disclosure from US-based companies, regardless of physical data location. This challenged the core of Europe’s data protection framework, essentially undermining any geographical boundaries.
The EDPS investigation into the Commission’s use of Microsoft 365, launched in May 2021, thus became a litmus test for the EU’s ability to impose its privacy principles on global digital behemoths.
When pressed on whether Microsoft could guarantee that French citizen data handled through Microsoft 365 would never be transmitted to US authorities without France’s authorization, Carniaux replied bluntly: “No, I cannot guarantee it.”
He elaborated that while the company has mechanisms for challenging overreaching requests, “a binding order from a U.S. court could prevail.” His technical counterpart, Pierre Lagarde, tried to reassure by noting that since January 2025, European customer data is contractually confined to the EU. But this attempt at mitigation rang hollow—the US CLOUD Act grants authorities access not through geography but corporate jurisdiction.
The investigation originally flagged three major violations in March 2024:
Privacy experts emphasize the obvious contradiction: Contracts are powerless before binding legislation. No matter how the contractual fine print evolves, American companies’ responsibilities to US authorities trump promises made to European customers and regulators.
So, why the loud regulatory celebration? And why accept contractual assurances that both parties privately admit are insufficient?
This ongoing litigation undermines any notion that the remedial measures negotiated in 2025 resolved the actual risks. The closure of the investigation is, in effect, a political settlement—one that leaves parties free to wage legal war elsewhere while regulators proclaim “mission accomplished.”
There is an inescapable conclusion: regulators embraced “compliance theater,” preferring the appearance of stringent oversight to the messy political reality that true protection may only come by forgoing US-based providers entirely.
But the events of 2025 show that compliance may be more political than practical. Institutional clients, with the leverage of public scrutiny and government negotiation, get special terms and extra attention. Everyone else is offered a watered-down version of these protections, with US law lurking in the background.
Marketing teams and commercial entities must recognize that if Microsoft cannot provide meaningful protection to its largest, most influential customers, then standard protections for commercial clients are likely even weaker. Certifications and audits will not insulate them from the Cloud Act’s reach.
Even the most robust contractual language—carefully drafted by European legal teams—cannot block a binding order from Washington, D.C. Data residency, once seen as a keystone of privacy, offers little practical benefit in the face of extraterritorial law.
The underlying tension has existed since the Schrems I and Schrems II cases, which dismantled previous transatlantic data transfer frameworks on similar grounds. Each regulatory cycle brings more elaborate paperwork and contractual safeguards—a cycle that privacy experts liken to rearranging deck chairs on the Titanic.
For businesses, this is a vital, if uncomfortable, lesson: true privacy for European data remains elusive when control ultimately rests beyond continental borders. Compliance, for many, will remain a symbol—a badge of participation in a system built as much on hope and appearances as on hard reality.
As regulators, cloud providers, and privacy advocates prepare for another round of legislative chess, the central paradox persists: contractual defenses are simply too weak when law itself is the adversary. Until Europe can enforce its privacy values on global infrastructure, or chooses to build sovereign alternatives, the cycles of compliance theater and legal schism are set to continue.

Background: The EU, Microsoft, and the Ongoing Battle for Data Sovereignty
Data sovereignty and privacy have become defining issues in the European Union’s tech regulation, especially as American cloud giants tighten their grip on digital infrastructure. For years, EU institutions have battled to ensure that the rights guaranteed by the General Data Protection Regulation (GDPR) are meaningful in practice—not just on paper.The stakes were raised when the US enacted the CLOUD Act, granting American authorities extraterritorial power to compel data disclosure from US-based companies, regardless of physical data location. This challenged the core of Europe’s data protection framework, essentially undermining any geographical boundaries.
The EDPS investigation into the Commission’s use of Microsoft 365, launched in May 2021, thus became a litmus test for the EU’s ability to impose its privacy principles on global digital behemoths.
Microsoft’s Senate Testimony: A Moment of Rare Corporate Candor
On June 10, 2025, a rare moment of clarity punctuated the typically smooth, jargon-laden narrative of transatlantic data transfers. Anton Carniaux, Microsoft France’s Director of Public and Legal Affairs, testified before the French Senate on digital sovereignty, confronting lawmakers’ questions with unvarnished sincerity.When pressed on whether Microsoft could guarantee that French citizen data handled through Microsoft 365 would never be transmitted to US authorities without France’s authorization, Carniaux replied bluntly: “No, I cannot guarantee it.”
He elaborated that while the company has mechanisms for challenging overreaching requests, “a binding order from a U.S. court could prevail.” His technical counterpart, Pierre Lagarde, tried to reassure by noting that since January 2025, European customer data is contractually confined to the EU. But this attempt at mitigation rang hollow—the US CLOUD Act grants authorities access not through geography but corporate jurisdiction.
The Regulatory Response: A Well-Choreographed Celebration
Despite this public admission of impotence before US law, European regulators pressed ahead. On July 28, 2025, the EDPS closed its lengthy Microsoft 365 investigation, confidently proclaiming that “the infringements identified in the EDPS’ 2024 Decision have been remedied.”The investigation originally flagged three major violations in March 2024:
- Failures in purpose limitation (using data for unauthorized secondary purposes)
- Inadequate controls over international data transfers
- Risks of unauthorized disclosure
The Limits of Contractual Protections: Legal Reality Versus Regulatory Illusion
But the foundation of this compliance is fragile—almost illusory. Microsoft’s own testimony confirmed that, under the Cloud Act, no contract, data mapping exercise, or residency guarantee can prevent a binding US court order from forcing disclosure.Privacy experts emphasize the obvious contradiction: Contracts are powerless before binding legislation. No matter how the contractual fine print evolves, American companies’ responsibilities to US authorities trump promises made to European customers and regulators.
So, why the loud regulatory celebration? And why accept contractual assurances that both parties privately admit are insufficient?
Contractual Box-Checking: A Masterclass in Bureaucratic Compliance
The Commission’s remedial measures read like a masterclass in compliance choreography tailored for institutional comfort more than practical security:- Data processing purposes are carefully defined—irrelevant if the US government can access the data anyway.
- International transfer risks are “addressed” through documentation and claimed legal adequacy—yet made moot by extraterritorial law.
- New notification procedures are introduced, yet they would be ineffective against secret US government demands or gag orders.
Two-Tier Protection: Government Institutions Versus Everyone Else
A particularly revealing development in the Microsoft-Commission saga is the creation of a two-tier protection system. Using its status as contracting authority, the Commission secured enhanced protection clauses for itself and other EU institutions. These include:- Explicit purpose limitation linked to public interest tasks
- Detailed mapping of data transfer destinations and legal justifications
- Disclosure clauses contingent on legal equivalence
Ongoing Court Battles: Compliance as a Political, Not Legal, Settlement
Perhaps the most telling sign of the regulatory charade is that both Microsoft and the European Commission have simultaneously challenged the original EDPS decision in the EU’s General Court. The Commission is seeking to overturn findings it claims are disproportionate; Microsoft seeks to annul the decision altogether.This ongoing litigation undermines any notion that the remedial measures negotiated in 2025 resolved the actual risks. The closure of the investigation is, in effect, a political settlement—one that leaves parties free to wage legal war elsewhere while regulators proclaim “mission accomplished.”
Regulatory Theater: A Pragmatic, Not Structural, Solution
Privacy advocates have been outspoken about the disconnect between EDPS declarations and the realities on the ground. Analysts note that neither the original EDPS findings nor its final report use plain terms to describe the risk of foreign government access. By avoiding direct acknowledgment of the Cloud Act’s reach, authorities sidestep the core incompatibility between EU privacy law and US surveillance policy.There is an inescapable conclusion: regulators embraced “compliance theater,” preferring the appearance of stringent oversight to the messy political reality that true protection may only come by forgoing US-based providers entirely.
Marketing Lessons: Compliance Certificates and Cloud Risk
For private organizations considering cloud adoption—especially in the marketing and advertising industries—the Microsoft case is a sobering lesson in regulatory risk. Many organizations base cloud vendor selection on supposed compliance with EU law, assuming that certified frameworks guarantee real protection.But the events of 2025 show that compliance may be more political than practical. Institutional clients, with the leverage of public scrutiny and government negotiation, get special terms and extra attention. Everyone else is offered a watered-down version of these protections, with US law lurking in the background.
Marketing teams and commercial entities must recognize that if Microsoft cannot provide meaningful protection to its largest, most influential customers, then standard protections for commercial clients are likely even weaker. Certifications and audits will not insulate them from the Cloud Act’s reach.
The CLOUD Act: Undermining European Data Protection at its Core
At the heart of the current impasse is the US Cloud Act itself. Passed in 2018, the law explicitly compels American companies to produce data demanded by US authorities, regardless of where data is stored globally. This legal leverage renders technical or contractual measures largely inert.Even the most robust contractual language—carefully drafted by European legal teams—cannot block a binding order from Washington, D.C. Data residency, once seen as a keystone of privacy, offers little practical benefit in the face of extraterritorial law.
The underlying tension has existed since the Schrems I and Schrems II cases, which dismantled previous transatlantic data transfer frameworks on similar grounds. Each regulatory cycle brings more elaborate paperwork and contractual safeguards—a cycle that privacy experts liken to rearranging deck chairs on the Titanic.
Timeline of the EDPS-Microsoft Saga
The protracted nature of this episode reflects the inertia and complexity endemic in international privacy regulation:- May 2021: EDPS opens investigation into the Commission’s use of Microsoft 365.
- March 8, 2024: EDPS issues its decision, citing multiple violations and ordering remedial actions.
- December 2024: The Commission submits a compliance report outlining improvements.
- February 2025: Microsoft updates its public data processing terms, influenced by Commission negotiations.
- June 10, 2025: Microsoft testifies before the French Senate, admitting it cannot guarantee data protection from US demands.
- July 3, 2025: The Commission sends details of additional measures to the EDPS.
- July 11, 2025: EDPS reviews information and concludes violations are remedied.
- July 28, 2025: EDPS formally announces closure, even as court challenges proceed.
The Vocabulary of Data Illusion
Several key terms underscore the artifice at play in this saga:- EDPS: The European Data Protection Supervisor—a body that declared “victory” while fundamental risks remained unresolved.
- Cloud Act: US legislation ensuring jurisdiction over American companies’ data holdings worldwide, overshadowing any contractual attempts at local protection.
- Contractual measures: Legal instruments used to create the appearance of protection but functionally ineffective against extraterritorial law.
- Data transfers: The movement of personal data that EU regulators seek to control, only to find their efforts neutralized by cross-border corporate compliance obligations.
- Compliance: A procedural status, now as likely to signify box-ticking as genuine safety.
- Purpose limitation: A heavily regulated and contractually defined principle, but ultimately powerless in the face of binding foreign orders.
- Microsoft 365: The flagship productivity suite that, despite its regulatory theater, serves as a case study in the limits of compliance.
- EU institutions: Customers with stronger contracts, yet no real immunity from US requests.
- Investigation: A multi-year regulatory process, now notable for its closure in the face of outstanding vulnerabilities.
- Disclosure: The act regulators hope to prevent, but cannot rule out as long as Cloud Act orders are legally binding.
Conclusion: The Future of Privacy in an Age of Regulatory Pantomime
The EDPS closure of its Microsoft 365 investigation, just after the company’s open admission of its legal vulnerabilities, is best understood as an act of regulatory pragmatism. In a world where national surveillance laws and global corporate structures intersect, the limits of European data protection have been reached—not through legislative failure, but through political compromise.For businesses, this is a vital, if uncomfortable, lesson: true privacy for European data remains elusive when control ultimately rests beyond continental borders. Compliance, for many, will remain a symbol—a badge of participation in a system built as much on hope and appearances as on hard reality.
As regulators, cloud providers, and privacy advocates prepare for another round of legislative chess, the central paradox persists: contractual defenses are simply too weak when law itself is the adversary. Until Europe can enforce its privacy values on global infrastructure, or chooses to build sovereign alternatives, the cycles of compliance theater and legal schism are set to continue.
