Prompt Engineering 2026: Complete SME Guide (ChatGPT, Claude, Gemini, Copilot)

Microsoft 365 Copilot: A Beginner's Guide for SMEs (2026)

To get started with Microsoft 365 Copilot, first check what you actually have: Copilot Chat, included at no extra cost with eligible Microsoft 365 subscriptions, or the paid Microsoft 365 Copilot license, which reads your mail, files and meetings. After that, three simple uses in Outlook, Teams and Word are enough for the first two weeks.

This guide is for SME owners, managers and employees who are opening Copilot for the first time, or who opened it once and had no idea what to ask. It does not tour every button. It explains which version you have, what to set up before switching it on, how to phrase a request, and where to start in each app. For the general method of writing instructions, which applies to every assistant, use our prompt engineering guide for SMEs.

Copilot, Copilot Chat, Microsoft 365 Copilot: what are we talking about?

At Microsoft, "Copilot" refers to several different products, and that confusion is the main reason beginners end up disappointed. An employee hears about an assistant that summarizes Teams meetings, clicks the Copilot icon, and finds a chat that knows nothing about their meetings. They simply do not have the same version.

An SME needs to tell three products apart:

VersionPriceWhat it doesWhat it does not do
Copilot (consumer app)Free with a personal accountGeneral chat, web search, imagesNo business data protection: avoid it for work
Copilot ChatIncluded with eligible Microsoft 365 subscriptionsSecure chat with a work account, answers based on the web and on files you give itDoes not search your mail, calendar or SharePoint files on its own
Microsoft 365 Copilot (paid license)Per-user license on top of Microsoft 365Works inside Word, Excel, PowerPoint, Outlook and Teams, using your mail, files, meetings and calendarOnly sees what the user is already allowed to open

The difference fits in one sentence: Copilot Chat answers from what you show it, while Microsoft 365 Copilot answers from what you are allowed to see across the company. Only the second one lets you ask "what was said about the Dupont account last week?" without pasting a single document.

On pricing, Microsoft announced in November 2025 a Microsoft 365 Copilot Business plan at 21 US dollars per user per month, excluding tax, on an annual commitment. It is reserved for organizations with up to 300 users on a Microsoft 365 Business plan (Basic, Standard or Premium). Local prices vary with billing options and current promotions, so check Microsoft's pricing page or your reseller when you buy.

Our advice for beginners: start with Copilot Chat, which you probably already have. Buy paid licenses later, for the roles where you have identified a specific gain.

Before switching Copilot on: three things to set up

The paid Copilot license respects existing access rights, which means it exposes every overly broad share in your SharePoint. If a "Salaries 2025" folder has been open to the whole company by mistake for three years, nobody noticed as long as someone had to go looking for it. With Copilot, an innocent question about pay can bring it to the surface.

Before rolling out, run these three checks with whoever manages your Microsoft 365, in-house or at your IT provider:

  1. Sharing. Review SharePoint sites and Teams channels open to "everyone", as well as anonymous sharing links. Focus on HR, finance and management folders.
  2. Accounts. Copilot works with a Microsoft Entra work account and, for mail features, an Exchange Online mailbox. Not all shared mailboxes are supported.
  3. Usage rules. Write one page on what is allowed: which types of documents, which personal data stay out, who reviews before anything is sent. Our article on shadow AI shows what happens when no such framework exists.

On confidentiality, Microsoft commits, for work accounts, not to use your prompts or data to train its foundation models. That does not exempt you from the GDPR: as soon as a customer's or employee's name goes into a request, you are processing personal data. For the European regulatory side, we have covered what the AI Act means for Microsoft 365 Copilot.

How to write a good request to Copilot

An effective Copilot request has four parts: the goal, the context, the source to use and the expected output. Microsoft presents this structure itself in its user guidance. It is the Copilot version of the general rules for writing a prompt, which we break down in our anatomy of a good prompt.

Compare these two requests in Outlook:

  • Beginner version: "Summarize my emails."
  • Effective version: "Summarize this week's exchanges with Martin Ltd about the maintenance quote (goal). I need to prepare a call with their director tomorrow (context). Use only the emails and Tuesday's Teams meeting (source). Give me 5 points at most, then a list of unanswered questions (expected output)."

The second one takes twenty seconds longer to write and saves three rounds of back and forth. With Microsoft 365 Copilot, you can point to a specific source by typing "/" in the input box and picking a file, an email or a meeting. It is the most useful habit to build in the first week: it cuts off-topic answers.

Three prompt engineering techniques apply directly to Copilot:

  • Give an example. Paste a meeting summary you are happy with and ask for "the same format". That is the idea behind few-shot prompting.
  • Ask for step-by-step reasoning. For an Excel analysis, ask for the method first, then the calculation. Our article on chain-of-thought prompting explains why this reduces errors.
  • Set a lasting frame. Copilot lets you save personal instructions (tone, language, preferred format). It works like a system prompt, which we explain in system prompt vs user prompt.

Where to start, app by app

Beginners progress faster by picking one use per app rather than testing everything in week one. Here are the first uses we recommend, from the simplest to the most demanding. Available features depend on your license and app version: some only exist with the paid license.

Outlook: sorting and replying

Start with summarizing a long thread (the summary button at the top of the message), then move on to draft replies. Ask for a short draft, read it, adjust the tone. Never let Copilot send a figure-based commitment (deadline, price, discount) without checking it: that is where mistakes get expensive.

Teams: meetings

With the paid license, Copilot can summarize a meeting and list decisions and action items per person, as long as the meeting is transcribed. Tell participants that transcription is on. A good beginner habit: ask "which questions were left unanswered?" at the end of every important meeting.

Word: start from a draft, not a blank page

Copilot is more reliable at rephrasing, shortening or restructuring existing text than at writing a document from scratch. Give it your notes and an older document of the same kind, and ask for a first version. Then work through it paragraph by paragraph.

Excel: asking questions about a table

Format your data as a structured table before asking Copilot anything, otherwise the answers will be rough. Ask for trends, a formula, a chart. Always check one or two figures by hand: an LLM can produce a wrong total with complete confidence.

PowerPoint: turning a document into a deck

Creating a presentation from a Word file looks impressive in a demo, but the result almost always needs rework. Use it to get an outline in ten minutes, not a finished client deck.

Limits to know from day one

Copilot makes mistakes, and they are all the more misleading because they rely on your own documents. An answer that quotes your sales tracking file looks reliable. It can still mix up two versions of the file, or invent a date that is not in the document. This is what is called an AI hallucination.

Four limits come up again and again in the SMEs we work with:

  • Outdated documents. Copilot does not know which version of a file is the reference. If three versions of a price list sit in SharePoint, it may answer with the wrong one.
  • Invisible sources. It cannot see anything outside Microsoft 365: your accounting software, your CRM, your paper files.
  • Overconfidence. A meeting summary can leave out an objection raised quickly. The participant who followed the whole discussion needs to review it.
  • Sensitive topics. Employee reviews, candidate screening, decisions about a customer: these uses come with specific rules and should not be handed to Copilot without a framework.

Copilot draws on your documents to answer, which resembles how RAG works: the quality of the answer depends on the quality of your files. Our article RAG vs prompting explains this logic, and our guide to understanding and avoiding AI hallucinations offers a simple checking method.

Copilot, ChatGPT, Claude or Gemini: do you have to choose?

For an SME already on Microsoft 365, Copilot has the integration advantage; that does not make it the best assistant for every task. Its strength is being present in Outlook, Teams and your files. For long-form writing, analysis of large documents or work on content outside Microsoft, other tools may fit better.

The choice depends first on your environment:

French data shows the question is no longer theoretical. According to the France Num 2026 Barometer published by the French Directorate General for Enterprise on 28 September 2026 (more than 9,000 businesses surveyed), 40% of French micro, small and medium businesses use AI, and 53% of SMEs. Only 19% use a paid tool, yet 85% of those users see a positive impact, compared with 68% of all users. Many SMEs on Microsoft 365 therefore already have Copilot Chat and do not use it.

A 30-day starter plan

Thirty days are enough to know whether Copilot brings a real gain to your SME, provided you measure it. Without measurement, the tool stays an impression: "it's handy" or "it doesn't work".

  • Week 1. Complete the three setup steps above. Pick three to five volunteers from different roles. Each one uses Copilot Chat for a single task: email summaries or rewriting.
  • Week 2. Each volunteer logs the time spent on the task before and with Copilot, and the number of corrections needed. Share the best requests in a common document.
  • Week 3. If you are testing the paid license, give it to the volunteers with the most meetings and email. Add Teams meeting summaries.
  • Week 4. Review: which uses save time, which ones need too much checking. Decide which licenses to buy and write the final one-page rules.

A 20-person SME that follows this plan knows after one month whether to equip 4 seats or 20. That is often the difference between a useful expense and licenses that sit idle.

Frequently asked questions

Is Copilot free in Microsoft 365?

Copilot Chat is included at no extra cost with eligible Microsoft 365 subscriptions, as long as you sign in with a work account. The version that uses your mail, files and meetings in Word, Excel, PowerPoint, Outlook and Teams requires a paid Microsoft 365 Copilot license per user.

What is the difference between Copilot Chat and Microsoft 365 Copilot?

Copilot Chat answers from the web and from content you provide; Microsoft 365 Copilot also answers from your work data. In practice, only the second can find last week's exchange on its own or summarize a Teams meeting you attended.

Can Copilot read my colleagues' documents?

Copilot only sees what the user is already allowed to open. The risk comes from overly broad access rights: a folder shared with the whole company by mistake becomes easy to find. That is why you should review SharePoint sharing before switching it on.

Is my data used to train Microsoft's AI?

For work accounts, Microsoft commits not to use your prompts or data to train its foundation models. This commitment does not cover the Copilot app used with a personal account. Your GDPR obligations remain in full.

How long does it take to become comfortable with Copilot?

Allow two to four weeks of regular use on real tasks. A short one-day training session focused on your documents and internal rules speeds things up considerably and prevents bad habits.

Should Copilot be rolled out to all employees at once?

No, a gradual rollout works better. Start with a few volunteers, measure time saved on specific tasks, then extend to the roles where the gain is proven. Buying licenses for the whole team from day one often leads to unused seats.
