Your email is GDPR-compliant today. Will it still be next year?

Your GDPR compliance depends on a court case you're not tracking

Here's an uncomfortable fact: the legal basis for your Google Workspace or Microsoft 365 email is a single framework that's currently being challenged in front of the same court that already killed its two predecessors. If you run infrastructure or make hosting decisions, this is worth ten minutes of your time.

Ask your IT partner if EU email in a US productivity suite is GDPR-compliant and you'll get a confident yes: both providers are certified under the EU-US Data Privacy Framework. Technically true. Also missing the point.

The legal stack, in short

• Sending personal data to a US company is a "transfer" under GDPR Chapter V (Articles 44-50).
• That's only lawful today because of the EU-US Data Privacy Framework (DPF), adopted July 2023.
• Its two predecessors, Safe Harbor and Privacy Shield, were both struck down by the Court of Justice of the EU (CJEU).
• The DPF is now under appeal at that same court.

Three attempts. Two collapses. One pending verdict. That's not a stable foundation to build a compliance program on.

"We use an EU data center" doesn't fix it

This is the part engineers get wrong most often. Region selection is not jurisdiction. Under the US CLOUD Act, a US company has to hand over data it controls when a US authority demands it, regardless of which data center it's sitting in. A Frankfurt or Amsterdam region owned by a US parent is still in scope.

Don't take my word for it. In June 2025, Microsoft France's director of legal affairs testified under oath before a French Senate inquiry. Asked directly if he could guarantee French citizens' data would never be handed to the US government without French authorization, his answer was: "No, I cannot guarantee that."

That's the provider, on the record, under oath.

Where things stand right now

• A challenge to the DPF (Latombe v. Commission) was dismissed by the General Court in September 2025, but only on facts as they existed in 2023. Nothing since then was considered. It's now on appeal to the CJEU.
• Microsoft was granted leave to intervene in that appeal. A company doesn't intervene in EU court proceedings unless it has serious skin in the game.
• The US oversight board that underpins the DPF (PCLOB) has been without quorum since January 2025.
• In June 2026, the US Supreme Court ruled FTC commissioners can be removed at will by the President. The FTC is the enforcement body for the DPF on the US side.
• FISA Section 702, the surveillance law at the center of the original Schrems II ruling, lapsed in June 2026 after failed extensions. Collection continues under existing court certifications regardless.

None of this means the DPF will definitely fall. It means your compliance posture depends on a decision you don't control, on a timeline you can't predict. Last time this happened (Schrems II, July 2020), companies had zero notice and a three-year gap before a replacement existed.

The AI layer adds more surface area

Copilot and Gemini are now embedded directly in mail and file storage. That's more data flows to account for:

# Questions worth asking your provider contract, literally:
- Does input get used for model training? (check tier, not marketing page)
- Can you delete a specific individual's data from a trained model? (usually no)
- Do you know which model processed which record, in which region?

The EU AI Act's transparency rules are already active (since August 2026). The heavier documentation requirements for HR, credit, and access-to-services use cases were pushed to December 2027, but that's a delay, not a way out. If you can't answer the questions above today, you won't be able to answer them then either.

The actual fix

If email, calendar, and file storage sit with a provider incorporated and operating entirely in the EU, no CLOUD Act exposure exists because there's no US legal entity to compel. That's not a mitigation, it's the absence of the transfer problem entirely.

As a data point: a Dutch provider offering this setup starts at €1.99 per mailbox per month, often cheaper than what teams already pay for Workspace or M365 licensing.

Practical takeaway

Check who actually handles mail for your domain (MX records will tell you the provider, not the jurisdiction, but it's a start). Then ask your provider the same question the French Senate asked Microsoft: can you guarantee this data is never handed over without our government's consent? If the answer is "no, but it hasn't happened," that's not a compliance guarantee, that's a probability bet.
