Over the last three years, Microsoft 365 for Business has evolved from a cloud productivity suite into a deeply integrated AI engine that touches every part of the digital workplace.
Since the launch of Copilot, Microsoft 365 for Business is becoming increasingly AI-centric.
But what will that look like for IT managers of SME’s and multinational corporations?
The short answer is architecting and governing a scalable, secure AI-driven ecosystem.
If you’re uncertain about how to navigate strategic and operational challenges that artificial intelligence (AI), offers, start with the question:
“How do we govern AI, secure it, and extract measurable value?”
Then follow the pointers in this article. We cover the foundational information you need to know about AI in Microsoft 365 for Business.
AI Is No Longer a Feature—It’s the Backbone of Microsoft 365
Microsoft has made its intentions clear: Copilot is now the centre of the Microsoft 365 experience. AI isn’t an add-on. It’s baked into workflows, admin centres, security tooling, SharePoint, Teams, and even desktop shortcuts.
For IT managers, this means:
- The organisation’s entire data estate becomes the “fuel” for Copilot.
- Users will increasingly expect automated workflows and personalised insights.
- Governance must be strong enough to prevent oversharing or inappropriate AI access.
- IT teams will need new skills in AI lifecycle management.
The days of “light-touch” Microsoft 365 administration are ending. AI adds complexity—but also significant capability if structured correctly.
What major changes should IT managers expect in Microsoft 365?
Microsoft 365 is defined by three core shifts:
- deeper AI integration,
- expanded security automation,
- and a more modular ecosystem.
AI Everywhere (and not just Copilot)
Microsoft is embedding AI into every layer of the M365 stack — not just Teams and Office apps. It’s also in Purview, Defender, Exchange Online, SharePoint, and admin tools.
What can IT managers expect from AI in Microsoft 365 for Business?
- AI will handle pattern detection, anomaly response, governance mapping, and even user training nudges.
- Zero Trust as the default operating model
- Layered add-ons instead of huge licence bundles — particularly around AI and security. Expect subscription stacks, more SKUs, and more micro-licensing decisions.
What IT managers need to do:
1. Plan for AI governance
Planning for AI governance is becoming essential. As Microsoft 365 embeds artificial intelligence deeply into security, productivity, and collaboration tools, governance is the framework that ensures AI operates safely, transparently, and in line with organisational risk tolerance.
The first step is defining clear policies around what AI is permitted to access, generate, and automate.
This includes establishing boundaries for sensitive data, setting acceptable use rules, and determining where human approval is required before AI can action a task. These policies must align with existing security, compliance, and data protection frameworks.
Next, build a role-based permission structure for AI tools like Microsoft Copilot. AI should not automatically inherit broad user privileges.
Instead, access should be scoped carefully, applying least-privilege principles and mapping AI capabilities to job functions.
Monitoring and auditing are also critical. AI decisions, generated content, and automated actions must be logged and reviewable. Continuous oversight ensures compliance, supports incident investigation, and helps refine policies over time.
Finally, we recommend ongoing user education. Employees need training on how to use AI responsibly, recognise risks, and follow organisational guidelines.
AI maturity is a cultural shift as much as a technical one.
2. Tighten identity baselines
The powerful tools in Microsoft 365 for businesses are designed to enforce strong authentication across all users and devices. Make the most of them by:
- Mandating multi-factor authentication (MFA) as a non-negotiable baseline Block legacy authentication protocols that bypass MFA entirely
- Strengthen conditional access policies by applying risk-based controls, least-privilege assignments, and continuous access evaluation.
- Standardise identity governance workflows for onboarding, role changes, and offboarding to eliminate permission creep.
- Use Entra ID Protection to detect compromised identities and automate remediation
3. Review licensing strategy annually
As AI capabilities evolve, Microsoft are expected to shift the goal posts on their premium features like Copilot, advanced security, or compliance tools.
We recommend reviewing your Microsoft 365 licensing strategy annually to ensure your organisation isn’t overpaying or that you are under-licensed.
4. Understand upcoming security defaults and deprecations
Changes to Microsoft 365 security defaults and deprecations can impact authentication, compliance, and AI-enabled workflows. Understanding which legacy protocols or features will be deprecated allows for proactive migration to modern, secure alternatives.
Security defaults — like MFA enforcement and conditional access policies — set baseline protections that should be aligned with your AI deployments to prevent data leaks or unauthorised access.
What data governance strategies support responsible AI usage?
AI is only as safe and effective as the data it can access. Without a mature data governance strategy, you risk data exposure, compliance violations, and poor AI accuracy.
IT leaders should:
- Implement data classification: Tag documents with sensitivity labels (e.g., Public, Confidential, Highly Confidential) to control AI access.
- Map data stores: Identify where critical business and customer data resides (SharePoint, OneDrive, Teams, Exchange) and segregate appropriately.
- Clean up legacy content: Archive or delete stale content so AI does not process irrelevant or sensitive old documents.
- Define retention policies: Use Microsoft Purview (or similar) to apply data lifecycle rules to both human- and AI-generated content.
- Protect data in motion: Ensure that file sharing, external collaboration, and access rights are closely managed.
How do identity and access control change when adopting AI in M365?
AI features like Copilot are deeply integrated with Microsoft Graph Explorer (a development tool), so access controls must be tighter, more precise, and continuously reviewed — especially if you’re working with offsite developers.
Strong identity controls ensure AI features don’t become a backdoor for data leakage or privilege escalation.
Key actions IT managers must take:
- Enforce Multi-Factor Authentication (MFA) or passwordless authentication for all users, including admins.
- Implement Conditional Access policies based on device compliance, location, and user risk profile to secure AI usage.
- Review Azure AD roles regularly, removing legacy accounts, stale privilege assignments, and dormant identities.
- Use Privileged Identity Management (PIM) for just-in-time elevation of admin roles, especially for AI or Copilot configuration.
- Segment AI access based on functional teams; for example, restrict certain Copilot agents to HR, Finance, or Project Management only.
What Are the Biggest Mistakes Companies Make in AI Adoption?
- Enabling Copilot before fixing permissions
- Thinking AI is “just a productivity tool”
- Not involving security teams early
- Poor change management
- Failing to define metrics with clear business outcomes early
- Forgetting to clean data — outdated information leads to poor AI output and confusion
What Training Do Users Need Before AI Rollout?
Many AI failures occur not because the technology is flawed, but because users were unprepared.
Training should include:
- How to ask effective prompts
- When not to use AI
- How to verify AI outputs
- How to recognise hallucinated information
- How to escalate concerns
- Data ethics and responsible usage
- Security training around AI phishing and misinformation
- Perform periodic training on a regular basis (i.e. half yearly or after major update)
What user adoption challenges should IT managers anticipate with AU in Microsoft 365 for Business?
AI adoption is cultural. Common challenges and suggested mitigations include:
- Scepticism or distrust: Users may fear AI will replace their jobs or make mistakes.
- Misuse or low adoption: Some may overuse or misuse AI, while others won’t use it at all.
- Data privacy worries: Employees could be concerned about how their prompts or generated content is stored and used.
- Skill gaps: Many users don’t yet know how to prompt AI effectively or recognise its limitations.
Mitigations:
Build a Change Management Plan
- Communicate benefits and governance openly
- Share success stories and pilot outcomes
- Highlight how AI augments—not replaces—their role
Hands-on Training
- Provide role-based AI training (e.g., for marketing, HR, operations)
- Offer “playground” environments to experiment safely
- Teach good prompting, validation, and AI ethics
Governance Education
- Explain your AI policies (what is allowed, what isn’t, why)
- Transparent logging and auditing of AI activity
- Feedback channels for AI misuse or concerns
Iterative Feedback Loops
- Use pilot user feedback to refine agents and policies
- Monitor usage metrics and adjust rollout strategies
- Celebrate early wins and build momentum
How can IT measure ROI, benefits, and risk from Microsoft 365 AI?
Measuring AI return on investment (ROI) requires both qualitative and quantitative metrics. Here are some KPIs and risk indicators to track:
Key Benefit Metrics:
- Time saved per user: Track how much time users save by using Copilot for summarising emails, documents, or meetings.
- Agent usage: Measure how often your custom Copilot agents are called, and by which teams.
- Productivity gains: Look at improvements in turnaround times, error reduction, or automated task completion.
- User satisfaction: Conduct regular surveys to understand how AI helps users and where friction exists.
Risk and Governance Metrics:
- AI-generated data logs: Volume of content created or modified by Copilot.
- Policy violations: Number of prompts flagged, blocked, or escalated.
- Access reviews: Ratio of privileged identities that are re-evaluated or revoked.
- Incident response speed: Reduction in time to detect and remediate AI-associated security issues.
Process for Measurement:
- Set baseline metrics before full rollout.
- Monitor ongoing usage and outcomes monthly.
- Adjust policies and training based on real data.
- Report findings regularly to leadership using clear dashboards.
Should SMEs and large enterprises govern AI differently?
The core principles of AI readiness apply across organisations, but scale and governance maturity differ significantly between SMEs and large enterprises.
For SMEs:
- Start simple: focus on a few high-impact use cases (helpdesk, summarisation, reporting).
- Use standard roles and licenses first — avoid spinning up too many custom agents.
- Leverage outsourced IT expertise to help with governance, identity, and deployment.
- Keep governance lightweight but enforceable: your AG (AI governance) committee can be small but must function.
For Multinationals:
- Develop a formal AI governance board with representation from security, legal, business units, and IT.
- Implement global policies with regional adjustments (e.g., data residency, compliance).
- Build a catalogue of AI agents mapped to business domain teams (HR, Finance, Sales).
- Automate AI policy enforcement and auditing across all offices.
- Invest in user adoption programs with regionally tailored training and change management.
