Is There a GDPR-Compliant AI That Runs Inside Microsoft Teams?

Introduction

Yes, there are AI solutions that run natively in Microsoft Teams and are fully GDPR-compliant. amaiko is an ISO 42001-conformant AI knowledge layer with 100% German hosting, working inside Teams and Outlook while running on its own infrastructure in German data centres. No separate applications, no new user interface, and your data stored outside the Microsoft cloud.

This article is written for IT leaders, managing directors and compliance officers in mid-sized companies that already use Microsoft 365 and are looking for a legally watertight AI solution for their corporate knowledge. You will learn why most off-the-shelf AI tools fail the General Data Protection Regulation, which technical and legal requirements actually have to be met, and how a persistent corporate memory works in practice.

The AI buddy: proactive support instead of passive waiting

While conventional AI tools wait for you to write the perfect “prompt,” amaiko works like a proactive colleague. Imagine starting your workday and your AI buddy already hands you a finished briefing: “Good morning. Here are today’s meetings, your open tasks and the emails from yesterday that still need a follow-up.” amaiko thinks ahead, prepares information before customer meetings, and makes sure you never walk into a conversation unprepared.

amaiko searches SharePoint, Teams chats and Outlook on demand, with each user’s own Microsoft 365 permissions, so nobody has to curate folders first. With the Meeting Notetaker add-on, meetings get minutes, decisions and action items without anyone writing them.

The direct answer: Microsoft 365 Copilot, Teams Premium and amaiko are the three central AI solutions natively integrated into Microsoft Teams. amaiko stands out through German hosting and a persistent corporate memory that keeps what it learns in your conversations, while it reads chats, emails and documents on demand.

What you will take away from this article:

• Why “EU servers” alone do not guarantee GDPR compliance
• The difference between session-based AI and a persistent knowledge layer
• Concrete technical and organisational measures for privacy-compliant AI use
• How the network of specialized agents works
• Practical steps for rolling out GDPR-compliant AI in your company

Why do off-the-shelf AI tools in Teams fail GDPR?

The General Data Protection Regulation governs the handling of personal data in the European Union and sets strict requirements for technical and organisational measures. Violations can trigger fines of up to EUR 20 million or 4% of global annual turnover — whichever is higher.

Using AI features in Microsoft Teams, such as transcription and live translation, requires a privacy assessment because personal data is processed. The mere existence of an AI solution does not guarantee privacy compliance — specific safeguards have to be put in place. For a deeper legal walkthrough, see our piece on GDPR-compliant AI in the enterprise.

A core issue with US-based AI solutions: the US CLOUD Act of 2018 gives US authorities the right, under certain conditions, to demand access to data held by US providers — even when that data sits in data centres inside the EU. Microsoft is certified under the EU-US Data Privacy Framework, which provides a legal basis for transfers, but additional safeguards are still recommended.

The problem with fragmented AI tools

Free or purely consumer AI tools often violate privacy policies because they use prompts to train models. Many companies end up with shadow IT structures: employees use external AI applications outside the controlled Microsoft 365 environment. By contrast, amaiko never uses your data to train global models. Your knowledge stays exclusively inside your “corporate safe” within German infrastructure.

This fragmentation creates several problems:

• Context switches between Teams, SharePoint, Outlook and external tools break the information flow
• Session-based AI loses context after each session: knowledge has to be rebuilt with every request
• Uncoordinated tool stacks make documentation and accountability towards regulators almost impossible
• Missing integration means conversation content from meetings is not automatically linked to corporate knowledge

For privacy-compliant operation, a valid data processing agreement (DPA) must be in place. With external add-on tools this is often missing or poorly defined.

That this integrated approach relieves the existing IT infrastructure while securing data protection is confirmed by real-world use in the German Mittelstand.

Frank Zimmermann, Application Consultant at BarthHaas, highlights the technical advantage: “In application consulting, everything revolves around seamless integration into existing system landscapes. amaiko does exactly that: it sits right at the ‘point of need’ in Teams and Outlook, so I never have to break my workflow for a separate interface. Finally an AI that speaks my language and puts an end to tool sprawl.”

For managing directors, alongside IT security, long-term value is paramount. Thomas Kugel, Managing Director at KUGEL Elektro- & Metalltechnik, sums it up: “With amaiko we have a direct connection to our systems, meetings in Microsoft Teams that run along and get summarised, and a central place where knowledge is preserved permanently. This lets us structure our day better, and important information no longer gets lost.”

How does Microsoft Copilot differ from a persistent AI knowledge layer?

Microsoft laid important groundwork with Phase 3 of the EU Data Boundary in February 2025. The question of whether Copilot is GDPR-compliant in 2026 stays open — because sovereignty is a question of defaults: Microsoft’s “flex routing” is on by default for EU/EFTA tenants created after March 25, 2026, and was rolled out to existing tenants from April 17, 2026 via Message Center notice MC1269223 — the exact default varies by tenant, so IT must actively check and disable it. When enabled, during peak load the actual processing of your prompt together with the retrieved emails, files and metadata may run in the US, Canada or Australia. On top of that, Copilot works reactively: its Copilot Memory keeps personal preferences across chats, but builds no shared company knowledge.

Integration depth and the ability to build persistent corporate knowledge differ significantly between the native AI options. amaiko offers a native AI knowledge layer that sits on top of the existing Microsoft 365 infrastructure and builds a persistent corporate memory from what it learns in your conversations, while reading chats, mails and documents on demand. For a deeper look at the architecture, see Which AI runs directly inside Microsoft Teams?. For the buyer’s lens, see the Microsoft Copilot alternative that stores knowledge and is GDPR-compliant. If you are weighing works-council sign-off and German hosting, this is exactly what a GDPR-compliant AI built natively into Microsoft Teams delivers.

Criterion	Microsoft Copilot	amaiko
Knowledge storage	Personal preferences (Copilot Memory)	Persistent: personal, team and company knowledge
Knowledge building	Manual / prompt-driven	Automatic
EU data sovereignty	In the EU Data Boundary, but flex routing can process outside the EU (US, Canada, Australia) — on by default for EU/EFTA tenants created after March 25, 2026; existing tenants must check MC1269223 and opt out	100% German hosting today
US CLOUD Act risk	Yes (US company)	Reduced: German company, data stored outside the Microsoft cloud; model inference on Azure OpenAI inside the EU

Documents inside Microsoft Teams do remain in the company’s secured cloud and are not uploaded to the public internet. But a real corporate memory needs more than secure storage — it needs a knowledge layer that automatically connects content and keeps it permanently available.

amaiko: the ISO 42001-conformant solution with German hosting

amaiko positions itself as a native AI knowledge layer over Microsoft Teams, SharePoint and Outlook. That means: not a replacement for existing Microsoft 365 services, but a layer that reads them on demand and keeps what it learns as lasting corporate knowledge.

ISO/IEC 42001 — the global standard for AI management systems — gives organisations guidance on governance, risk management and the ethical and legal aspects of developing or using AI systems. amaiko is aligned with this standard and therefore meets the requirements for documentation, transparency, accountability and data quality. For a deeper analysis of the standard, see our article on ISO 42001 – certified or merely aligned?.

Concrete day-to-day benefits:

• −57% onboarding time for new employees, thanks to immediate access to relevant organisational knowledge
• −35% search time in everyday information lookups
• No manual documentation, no wiki gardening
• Summaries of Teams chat histories on request
• Structured minutes and action lists from meetings with the Meeting Notetaker add-on

How does the network of specialized agents work?

amaiko runs a multi-agent network that draws on specialised AI agents. This architecture delivers more precise, more contextual answers than generic AI assistants.

“A growing team of experts. One buddy.”

Each agent is specialised in a specific business area, from analysing meeting transcripts and producing documentation to processing conversational content. For complex questions, multiple agents collaborate to find the best answer.

The user benefit: you ask a question in your familiar Teams or Outlook environment, and the right expert network is activated automatically. No new learning curve, no prompt training, no separate application.

GDPR grants data subjects extensive rights, including the right to access, correct and delete their data. In a multi-agent system, permission management therefore has to be precise. amaiko ensures that AI agents only access information the requesting user is authorised to see.

Persistent corporate memory instead of session-based AI

The fundamental difference between session-based AI tools and a persistent knowledge layer shows up in how corporate knowledge is handled:

Session-based AI (e.g. standard chatbots):

• Context is lost after every session
• Identical questions require identical explanations
• Knowledge only lives in employees’ heads
• When employees leave, knowledge leaves with them

Persistent corporate memory (amaiko):

• Knowledge is retained permanently and grows continuously
• Proactive supply of relevant information ahead of customer meetings
• Meeting outcomes flow into your personal knowledge automatically (Meeting Notetaker add-on)
• Knowledge stays available even when employees leave the company

AI in Microsoft Teams can automatically produce structured minutes and action lists from meetings. With the Meeting Notetaker add-on, amaiko goes one step further: summaries stay searchable permanently, action items land in Microsoft To Do, and decisions flow into the user’s personal knowledge.

US CLOUD Act vs. EU Data Boundary: why “EU servers” alone are not enough

A critical insight for every privacy officer: even with German or EU hosting of an AI system operated by a company headquartered in the US, access under the CLOUD Act is theoretically possible.

Microsoft has made significant progress with the EU Data Boundary. Phase 3 was completed in February 2025, and in the 16 months before that the company invested more than USD 20 billion in AI and cloud infrastructure in Europe. Yet Microsoft, as a US company, remains subject to the US CLOUD Act, regardless of where the servers physically sit.

Using Microsoft 365 settings to store data in the EU is important for GDPR compliance, but not sufficient. What matters is:

• Ownership structure of the AI vendor
• Contracting party and its legal entity
• Location of the legally relevant organisation
• Access possibilities of personnel outside the EU

As a German company with German hosting, amaiko itself is subject only to EU and German law. Your data is stored in Germany on amaiko’s own infrastructure, not in the Microsoft cloud; the AI model runs on Azure OpenAI with processing inside the EU only.

EU AI Act 2026: aligned from day one

The EU AI Act (Regulation (EU) 2024/1689) entered into force on 1 August 2024 and has applied since 2 August 2026, with exceptions: the AI Omnibus moved the rules for high-risk areas such as employment and education to 2 December 2027, and those for AI in regulated products to 2 August 2028. An assistant for everyday knowledge work is not one of those high-risk areas; for companies that use one, the AI literacy duty has applied since February 2025.

amaiko is aligned with the EU AI Act:

• A data processing agreement and documented technical and organisational measures support your accountability under Art. 5 (2) GDPR
• Transparent documentation for supervisory authorities
• Users can have amaiko correct or delete what it remembers
• Future-proof solution for tightened privacy requirements

ISO 42001 conformance is a powerful aid for meeting EU AI Act requirements, particularly around documentation, transparency, accountability and data quality.

What technical and organisational measures (TOMs) are required?

The compliance posture of AI in Teams depends on licensing and administrative hardening. amaiko brings the contractual and technical groundwork for a fast rollout:

Technical measures:

• Encryption of data in transit and at rest
• Granular access controls in the admin centre
• AI processing on Azure OpenAI inside the EU only
• All data is stored on isolated German servers operated by amaiko, outside the Microsoft cloud; AI inference runs on Azure OpenAI inside the EU only

Organisational measures:

• Regular security audits
• Documentation of all privacy measures for compliance evidence
• When AI is used to process personal data, a data protection impact assessment (DPIA) under Art. 35 GDPR must be examined and is in many cases legally required. amaiko actively supports data protection officers in carrying out and documenting one.

Using Microsoft Teams calls for a structured review and clean implementation of general data protection rules. amaiko takes much of this work off administrators’ shoulders: the data processing agreement comes ready to sign, and running the servers is amaiko’s job, not yours.

Common challenges and solutions for AI in Microsoft Teams

AI rollouts in companies usually fail not because of the technology itself, but because of practical hurdles. Here are the most common problems and how amaiko solves them.

Problem: complex IT implementation

Many AI products require sprawling IT projects, infrastructure changes and months-long implementation phases.

Solution: amaiko needs no IT project phase, just a connection to your existing Microsoft 365 account. The native integration means: no infrastructure for you to run, no separate website. amaiko runs on its own servers in Germany. You keep working in Teams, Outlook and SharePoint while amaiko sits on top as an intelligent knowledge layer.

Problem: employee training effort

New tools usually mean new UIs, new workflows and weeks of onboarding training. Productivity dips before it recovers.

Solution: there is no new user interface. Employees keep working in their familiar Teams and Outlook environment. The AI buddy fetches the context it needs from Teams, Outlook and SharePoint itself, so no prompt training is needed. Using it feels like working with a colleague who always has the right answer ready.

Frequently asked questions (FAQ)

Is amaiko really GDPR-compliant, and where is the data stored?

Yes, amaiko is fully GDPR-compliant. All data is hosted exclusively on servers in Germany. As a German company, amaiko itself is not subject to the US CLOUD Act; data is stored in Germany outside the Microsoft cloud, and the AI model runs on Azure OpenAI with processing inside the EU only. amaiko’s AI management is aligned with ISO 42001, the international standard for AI management systems, including data protection and security.

How does amaiko differ from Microsoft 365 Copilot?

The central difference lies in how knowledge is handled. Copilot is reactive: Copilot Memory keeps personal preferences across chats, but builds no shared company knowledge. amaiko builds a persistent corporate memory from what it learns in your conversations, as personal, team and company knowledge, and keeps it permanently available. amaiko also offers 100% German hosting today, whereas Copilot’s ‘flex routing’ setting can send AI processing outside the EU (US, Canada, Australia) during peak load — on by default for EU/EFTA tenants created after March 25, 2026, and rolled out to existing tenants via MC1269223, so IT must actively check and disable it.

Does amaiko require separate employee training?

No. amaiko works directly inside the familiar Teams and Outlook environment. There is no new user interface, no separate application and no learning curve. Employees ask questions as they would with a colleague — the AI buddy fetches the context it needs from Microsoft 365 itself.

How does persistent memory compare to session-based chatbots?

Session-based AI assistants lose context after every session. You have to start over with each request. amaiko stores and links knowledge continuously: with the Meeting Notetaker add-on, the summary of a meeting six months ago is just as retrievable as content from yesterday’s email. The knowledge grows with use and stays in place even when employees leave the company.

What does amaiko cost compared to Microsoft 365 Copilot?

amaiko costs €41.58 per user per month billed annually (€499 a year), or €49.90 billed monthly, bookable from 5 seats. Microsoft’s seat is cheaper: Copilot Business costs €18.20 per user per month billed annually for up to 300 users, as an add-on to an eligible Microsoft 365 plan, and Cowork, its proactive work, is billed by usage on top. amaiko’s seat includes unlimited tokens, briefings and Active Inbox, with company knowledge that stays and hosting in Germany outside the Microsoft cloud.

Can amaiko be integrated with existing tools like HubSpot or Personio?

Yes, absolutely. amaiko is designed to sit as a central intelligence layer over all of your important business tools. While native embedding in Microsoft Teams and Outlook powers daily access, amaiko draws its knowledge from a range of sources:

• CRM & sales: seamless connection to tools like HubSpot or Dynamics 365 Business Central, linking customer data directly with meeting briefings or email drafts.
• HR & organisation: integration with Personio to make knowledge about internal processes, onboarding guidelines or absences proactively available.
• Business suites: alongside deep Microsoft 365 integration (SharePoint, OneDrive, OneNote, To Do), amaiko connects further line-of-business systems such as DATEV, Jira or Asana through its marketplace, with custom connectors on request.

What does ISO 42001 mean for companies?

ISO/IEC 42001 is the international standard for AI management systems. It covers governance, risk management and ethical and legal aspects. For companies it means: documented processes, demonstrable compliance and readiness for the EU AI Act, which has applied since August 2026.

How quickly can amaiko be integrated into an existing Microsoft Teams environment?

Integration happens without a classic IT project phase. After you connect your Microsoft 365 account, amaiko reads your recent emails, calendar and chats once to build a starting profile of how you work. Administrators can configure permissions and access controls in the admin centre.
