AI Agents in Microsoft 365: What They Can Do and What They Can See

ByHilt Digital

Short answer: AI agents in Microsoft 365 are Copilot features that can carry out tasks, not just answer questions: summarising a project from its files, drafting replies from past emails, or following a set process. They work with the permissions of the person using them. So an agent can reach everything that person can reach, including every file that’s been shared too widely. Before you switch agents on, fix who can see what.

Agentic AI is arriving inside the software small businesses already pay for, not just as separate products. Microsoft is building agents into Copilot, Teams, SharePoint and Outlook. That makes them easy to try, and easy to switch on before anyone’s checked what they’ll be able to see. For the wider picture of agentic AI, including tools outside Microsoft, see our guide to agentic AI for small businesses.

What an agent in Microsoft 365 actually does

A chatbot answers what you ask. An agent works towards a goal. In Microsoft 365, that means things like:

  • Pulling together everything about a client or project from emails, Teams chats and SharePoint files into one summary.
  • Answering staff questions from your own policies and procedures, such as an HR or IT help agent.
  • Drafting responses based on how similar requests were handled before.
  • Following a defined process, such as collecting information for a new starter and preparing the paperwork.

Agents can be built into Copilot or created by your own team with Microsoft’s tools. Either way, they do their work with the data they can reach.

The catch: agents see what users see

An agent working for a member of staff can access whatever that member of staff can access. That sounds safe until you look at how most small businesses’ files are actually shared. Years of “share with everyone” links, a SharePoint site the whole company can read, a salary spreadsheet in a folder nobody locked down, a former director’s OneDrive that’s still accessible. People rarely stumble on those files by accident. An agent searching on their behalf will find them in seconds.

That’s the real risk with AI agents in a small business. Not that the AI misbehaves, but that it faithfully surfaces what was already overshared. We cover the clean-up in detail in preparing Microsoft 365 permissions for a safe Copilot rollout.

Five things to do before switching agents on

  1. Find the overshared files. Review “anyone” and “everyone” sharing links, company-wide SharePoint sites and old OneDrives.
  2. Label what’s sensitive. Sensitivity labels in Microsoft 365 let you mark HR, finance and client data so agents and people handle it properly.
  3. Lock down sign-in. Multi-factor authentication on every account. DSIT’s 2025 survey found only 40% of businesses use it on email, and an agent acting for a compromised account is a serious problem.
  4. Decide who can build agents. Just as you’d control who can install software, control who can create and publish agents.
  5. Write a short AI policy. What staff can use AI for, what data must never go into it, and who to ask. Our AI policy playbook has a starting point.

Start small, with one agent and one team

The sensible way to start is one well-defined job, for one team, with data that’s already tidy. Measure whether it saves time, check what it touched, then widen it. Licensing matters too: some agent features come with Microsoft 365 plans you may already have, and others need a paid Copilot licence, so check before buying. Our guide to auditing Copilot usage covers avoiding licences nobody uses.

Agents are software with access to your data, so they’re part of your software supply chain as well.
