Microsoft 365 Copilot can save real time: summarising long email threads, drafting documents from your own files, and pulling together notes from Teams meetings. But whether it is useful, or a risk, depends far more on how your Microsoft 365 is set up than on the AI itself.

The most important thing to understand is this: Copilot can only see what each person already has access to. It does not bypass permissions. The catch is that in most businesses, people have access to far more than anyone realises, and Copilot makes all of it easy to find.

Here are the eight things we check before recommending Copilot to a business.

1. You are on a plan that supports Copilot

Microsoft 365 Copilot is an add-on licence. It sits on top of an eligible Microsoft 365 plan, which for most small and medium-sized businesses means Business Basic, Business Standard or Business Premium. If you are still on older or mixed licences, sort those out first, and check Microsoft’s current eligibility list before you buy.

You do not need to license everyone. Most businesses start with a small group.

2. Your files live in OneDrive, SharePoint and Teams

Copilot works with content stored in Microsoft 365. Files on a local server, on someone’s desktop, or still in Google Drive or Dropbox are invisible to it. If your important documents are not yet in Microsoft 365, Copilot will give thin answers, and the first job is a proper move of your files.

3. You know who can see what

This is the big one. Over the years, sharing tends to grow without much thought:

  • folders shared with “Everyone” or “Everyone except external users”
  • old “Anyone with the link” sharing links that still work
  • Teams and SharePoint sites created for one project that half the company can still open
  • leavers’ OneDrive files that were shared widely

Before Copilot, these were hard to stumble on. With Copilot, someone asking “what are we paying our staff?” may get an answer if a salary spreadsheet is shared too widely.

Microsoft provides reports in the SharePoint admin centre that show oversharing, and some of the more detailed tools are included with Copilot licences. Run them, then tighten anything that is shared more widely than it should be.

4. Your most sensitive data is labelled

Sensitivity labels mark documents as, say, Confidential or Internal Only, and can restrict who can open them. They also tell Copilot to treat that content carefully. You do not need to label everything: start with the obvious candidates such as HR, finance, board papers and client contracts.

5. Sharing settings match how you work

Check your organisation-wide sharing settings in SharePoint and OneDrive. For most small businesses, sensible defaults are: new links shared only with specific people, external sharing allowed only where needed, and “Anyone with the link” turned off or tightly limited.

6. Security basics are in place

Copilot makes it easier to find information, which also makes a compromised account more damaging. Before rolling it out, make sure:

  • multi-factor authentication is enforced for everyone, especially admins
  • legacy sign-in methods that bypass it are blocked
  • admin accounts are separate from day-to-day accounts

If you are not sure where you stand, a Microsoft 365 security check will tell you quickly.

7. You have a simple AI usage policy

Many teams are already using AI tools informally, often personal ChatGPT accounts. A short policy sets expectations: which tools are approved, what data must never go into them, and that people remain responsible for checking AI-generated work. One page is enough.

8. You have a plan to measure whether it is worth it

Copilot licences are a significant per-person cost, so treat the first rollout as a pilot:

  • pick 5 to 15 people across a few roles who will actually use it
  • give them practical training on their own day-to-day work, not a generic demo
  • agree in advance what you will measure, such as time saved on specific tasks
  • review after six to eight weeks and decide whether to expand, adjust or stop

The bottom line

If you can tick all eight, you are in a good position to try Copilot. If items 3 to 6 make you uneasy, that is normal: most businesses find their permissions need work. Fixing them is worthwhile whether or not you go on to use Copilot, because it reduces your risk either way.

We help businesses get ready for Copilot and run measured pilots at a fixed price. See how our Copilot readiness service works, or get in touch and we will tell you honestly whether it is worth it for you.
