Microsoft 365 AI compliance is fast becoming a critical priority as artificial intelligence transforms how businesses operate. Tools like Microsoft 365 Copilot are reshaping productivity—but they also introduce new challenges for data governance, security, and regulatory alignment.
In a recent episode of the All Things M365 Compliance podcast, I joined Ryan John Murphy and Rafah Knight, founder of Secure AI, to explore how organisations can adopt AI responsibly within Microsoft 365. From mitigating shadow AI risks to aligning with the EU AI Act, we unpacked what legal, IT, and compliance teams need to know.
Here are the key takeaways for managing AI governance and compliance in the Microsoft 365 environment.
🚀 AI as a Strategic Compliance Asset
AI is not just a tool for productivity—it’s a compliance enabler when used strategically. It can reduce manual effort, automate complex tasks, and enhance oversight in ways traditional methods can’t.
“AI gives us time back—time to be creative, strategic, and innovative.” — Rafah Knight
AI enhances compliance by:
- Classifying sensitive data using Microsoft Purview
- Automating DSAR responses with Microsoft 365’s eDiscovery tools
- Enhancing risk detection via intelligent auditing and analytics
- Identifying ungoverned content that may violate retention or regulatory requirements
🔢 Key Stat:
- 70% of employees are already using AI tools at work—often without IT’s knowledge (Microsoft Work Trend Index, 2024).

🔐 Why Microsoft 365 Copilot Is Designed for AI Compliance
Microsoft Copilot is fundamentally different from consumer-grade AI. It runs within your Microsoft 365 tenant, applying the same controls that already govern your data security, privacy, and compliance strategy.
“Microsoft Copilot doesn’t introduce new risks—it helps you manage the ones you already have.” — Rafah Knight
Copilot inherits your:
- Data classification and sensitivity labels
- DLP, retention, and audit configurations
- Microsoft Purview data lifecycle and compliance settings

⚠️ Shadow AI: The Hidden Risk
Shadow AI occurs when employees use unauthorized AI tool, such as ChatGPT or Deepseek, for work tasks, often bypassing IT governance. This poses a significant risk to data security, compliance, and regulatory adherence.
“Your AI journey didn’t start when you bought a license—it began when your employees started using ChatGPT on their personal devices.” — Rafah Knight
Risks associated with Shadow AI include:
- Loss of sensitive data to external, unmonitored systems
- Lack of audit trails or visibility for regulators
- Personal AI usage becoming embedded in business workflows

🧭 Governance Isn’t Optional
AI governance isn’t a product feature; it’s a process that must be woven into your organization’s culture and operations.
“Governance isn’t a feature—it’s a process.” — Rafah Knight
To ensure responsible AI adoption, Rafah recommends:
- Defining usage policies and approval workflows
- Building role-based personas to enable secure adoption
- Aligning to regulatory frameworks like the EU AI Act and NIST AI RMF
- Using Microsoft Purview for monitoring, classification, and lifecycle management
Culture shift for CIOs:
AI adoption isn’t just a technology upgrade; it requires a cross-functional change management effort. CIOs should:
- Establish an AI Centre of Excellence with representatives from IT, Compliance, HR and Legal
- Develop persona-driven enablement programmes: e.g. “Copilot for Finance,” “Copilot for Legal” workshops
- Appoint data stewards in each department to champion responsible AI usage
- Embed AI governance into your existing change-management framework (e.g. ADKAR) to ensure sustained adoption

⚖️ EU AI Act: What It Means for Microsoft 365 Copilot and AI Compliance
The EU AI Act introduces a risk-based framework classifying AI systems as:
- Minimal risk → low or no regulatory burden
- Unacceptable risk (e.g., social scoring) → banned
- High-risk (e.g., hiring, finance, law enforcement) → strict controls
- Limited risk → transparency obligations
So where does Microsoft 365 Copilot fit?
“Many teams say ‘we can’t do this because of the AI Act’—but it often doesn’t apply to adopters. It targets developers.” — Rafah Knight
Most Microsoft 365 Copilot activities, such as document summarization or email drafting, fall into the limited or minimal risk categories. However, the risk classification depends on how you use Copilot.
High-risk scenarios to watch for:
- Automated decision-making in HR or finance
- High-impact use in legal or healthcare contexts
- Sensitive data processing without human oversight
To stay compliant:
- Conduct risk assessments for your Copilot use cases
- Use audit logs and Microsoft Purview to maintain transparency
- Provide human oversight where required
- Ensure AI usage aligns with Microsoft’s Responsible AI Standard
✅ Practical Checklist:
- Map use cases to AI Act categories
- Document justifications and controls
- Align tools with data protection regulations (e.g., GDPR, UK DPA)
- Establish governance committees and approval workflows

FAQ
What is Microsoft 365 Copilot?
Microsoft 365 Copilot is an AI assistant built into apps like Word, Excel, Outlook, and Teams. It uses large language models (LLMs) combined with Microsoft Graph data to help users draft content, summarize documents, analyze information, and automate repetitive tasks. All activity stays within your Microsoft 365 environment and respects your organization’s existing compliance and security policies.
Is Microsoft 365 Copilot safe to use for compliance purposes?
Yes. Microsoft 365 Copilot operates entirely within your Microsoft 365 tenant, inheriting your existing compliance controls—like sensitivity labels, data loss prevention (DLP), audit logging, and retention policies. Unlike consumer AI tools, Copilot does not send data to third-party platforms or use your content to train public models.
What is shadow AI and why is it a risk?
Shadow AI refers to the use of unauthorized AI tools—such as ChatGPT or Bard—by employees without IT approval. These tools fall outside your organization’s governance framework, putting sensitive data at risk, violating regulatory requirements, and creating blind spots in audits and incident response.
How does the EU AI Act apply to Microsoft 365 Copilot?
The EU AI Act classifies AI systems into risk tiers: minimal, limited, high, and unacceptable. Most Copilot scenarios fall under the minimal or limited risk categories. However, if Copilot is used for high-stakes decisions (e.g., hiring or credit evaluations), it may qualify as high risk, requiring additional safeguards like transparency, documentation, and human oversight.
Organizations should classify their use cases, document risk assessments, and align Copilot usage with the Act’s requirements and Microsoft’s Responsible AI Standard.
What compliance frameworks should guide AI governance in Microsoft 365?
Organizations should align their AI strategy with established governance frameworks, including:
NIST AI Risk Management Framework (AI RMF)
EU AI Act
Microsoft Responsible AI Standard
GDPR and other regional data protection laws
These frameworks provide best practices for managing AI risk, ensuring transparency, and embedding human oversight.
How can organizations implement responsible AI governance in Microsoft 365?
Start with a formal AI usage policy that defines approved tools, high-risk activities, and roles responsible for oversight. Use Microsoft Purview to classify data, enforce access controls, and retain AI-related activity logs. Provide role-based training and enablement to help users adopt tools like Copilot responsibly and securely.
Can Copilot activity be audited in Microsoft 365?
Yes. All Copilot interactions can be captured in the Microsoft 365 unified audit log and surfaced through Microsoft Purview. Admins and compliance teams can monitor how Copilot is being used, identify data access patterns, and investigate incidents if needed, ensuring transparency and forensic readiness.
Does Microsoft use my data to train Copilot?
No. Microsoft does not use your organizational data, prompts, or Copilot outputs to train large language models. All data remains within your Microsoft 365 environment and is governed by your tenant’s security, compliance, and privacy settings.
What are some best practices for secure AI adoption in Microsoft 365?
To adopt AI securely and responsibly:
Use Microsoft 365-native tools like Copilot
Classify and govern data with Microsoft Purview
Train users based on role-specific AI personas
Conduct risk assessments for AI use cases
Align to frameworks like NIST AI RMF and the EU AI Act
Continuously monitor and audit usage through built-in tools
