Is Your Microsoft 365 Ready for AI? 5 Questions Before Rolling Out Copilot

Before You Give Copilot Access, Ask Who Already Has It

If you’re worried about AI accessing your company’s information, start with a simpler question: who can access that information today?

I’m currently studying Microsoft’s AB-900 course, and it’s changing how I think about AI in the workplace.

Working in IT across multiple retail sites, I naturally think about deployment: getting tools running, helping people use them and solving problems.

But studying Copilot has pushed another question to the front:

What needs to be in place before we scale this?

Microsoft’s AB-900 study guide allocates 35–40% of the exam to data protection and governance. That’s a substantial part of learning to administer an AI-enabled Microsoft 365 environment.

And it matters whether you’re running a startup, supporting a growing business or evaluating companies as an investor.

Your existing permissions deserve a closer look

Microsoft 365 Copilot only surfaces organisational information the user already has permission to view. It doesn’t automatically give everyone access to everything.

That’s reassuring until you consider what people might already have access to.

Imagine a growing company where a confidential planning document sits in a broadly shared SharePoint folder. Nobody intended every employee to read it, but the permissions allow it.

My takeaway: AI can make existing oversharing more consequential by making information easier to find.

Microsoft’s own deployment guidance recommends reviewing excessive access, sharing links and site ownership as part of preparing your data environment.

Agents add another question: whose access are they using?

An AI agent might answer questions or carry out a task using connected tools.

Here, the details matter. In Copilot Studio, tools can use end-user credentials or maker-provided credentials, depending on configuration. You shouldn’t assume every agent action runs solely with the permissions of the person chatting with it.

Before introducing one, I’d want clear answers to five questions:

• Who owns this agent?

• What information and systems can it access?

• Whose credentials does it use?

• Who approves its release?

• When will we review its access and usefulness?

These are practical questions a business should be able to answer as it grows.

If you’re hesitant about AI, start with something small

I understand why people hesitate. “Trust the AI” isn’t a particularly convincing business case.

A more useful starting point would be a limited pilot: one team, one recurring problem and a reviewed set of information.

For example, test whether an assistant can help staff find approved internal procedures. Check its answers against the source documents. Record errors. Measure whether it actually saves time, including the time spent checking its work.

That gives your team evidence to discuss.

For founders and scale-ups, it’s a way to explore value while keeping responsibility clear. For investors, I’d ask a portfolio company to explain both the benefit it has measured and who owns the deployment.

Where I’m at

I’m still learning AB-900. I’m sharing the questions it’s helping me ask, rather than claiming I’ve solved every part of AI adoption.

The lesson I’m taking forward is this:

Confidence in AI grows when people understand its boundaries and can see that it helps.

If your business uses Microsoft 365, what would help you take the next step with AI: clearer data controls, better training or a practical example that proves its value?
