Microsoft Copilot is the artificial intelligence assistant most companies have already paid for. Many use it as a general-purpose chatbot, and miss what actually makes it useful.
My review fits in three sentences. Copilot earns its price when your teams genuinely live inside Microsoft 365. It turns into an expensive gadget when nobody shows them what it can do with their own data. And the price the vendor advertises never matches the price you pay.
What Microsoft Copilot became in 2026
The product changed name. The vendor documentation states that Microsoft 365 Copilot is now called Microsoft Copilot, and that Microsoft 365 Copilot Chat becomes Microsoft Copilot Chat. The rename carries no consequence for security or compliance.
The scope moved far more than the name. Copilot lives inside Word, Excel, PowerPoint, Outlook and Teams. It also ships ready-made agents, Researcher and Analyst, plus an agent workshop, Copilot Studio. You can connect your internal sources to it.
I summed up that shift in a LinkedIn post from May 2026. Many companies still roll out Copilot the way they rolled out an office suite twenty years ago. They sign the licences, send an announcement email, and wait. That method produces nothing.
Microsoft Copilot pricing, what you actually pay
Microsoft Copilot costs 26.00 euros excluding tax per user per month for enterprises, billed annually. The vendor states on its own pricing page that a qualifying Microsoft 365 licence is still required on top. The add-on never sells on its own, pricing checked in October 2026.
For smaller companies, the Business plans page reads more clearly, because it shows bundles that already include the office suite.
| Plan | Monthly price | What the line covers |
|---|---|---|
| Copilot Business add-on | 18.20 € | A qualifying Microsoft 365 Business subscription still required on top |
| First-year promotion | 15.60 € | Existing customers, offer running until 31 December 2026 |
| Business Standard and Copilot | 20.36 € | Office suite and Copilot in a single line |
| Business Premium and Copilot | 27.73 € | Same thing, with security and compliance included |
| Microsoft Copilot, enterprise | 26.00 € | A qualifying Microsoft 365 licence still required on top |
Agents are billed separately again. Copilot Studio runs on consumption, through Copilot credits valid across the whole tenant. A pack of 25,000 credits costs 173.30 euros excluding tax per month. Each agent response consumes a variable number of them.
An honest budget therefore adds three lines. The Microsoft 365 licence, the Copilot add-on, and the consumption of the agents you will end up building. That is the line we most often add back to the quotes companies show us.
Without a Copilot licence, access is never guaranteed
Many companies plan to test the tool for free before buying. The nuance deserves a full read. The vendor documentation separates priority access, reserved for licensed seats, from standard access for everyone else.
The wording is explicit. Standard access stays subject to service capacity and may vary throughout the day. During periods of high demand it can be temporarily restricted. The vendor adds that this behaviour is no malfunction, and that it protects service stability for licensed seats.
Voice features are reserved for priority access. A pilot run on unlicensed seats therefore gives a distorted picture of the product. We advise buying a handful of licences for the pilot team, rather than testing a degraded version.
Why Claude models are switched off by default in Europe
Copilot no longer runs only on OpenAI models. Anthropic models are now available in Copilot, in Researcher, in Copilot Studio and across Microsoft 365 apps. They are enabled by default for most commercial cloud customers.
Europe is the exception, and the reason is written plainly. The vendor page, updated in September 2026, places those models outside the EU Data Boundary. Customers in the European Union, the European Free Trade Association and the United Kingdom therefore receive them disabled.
Switching them on takes an explicit action. An AI Administrator or a Global Administrator ticks the setting in the Microsoft 365 admin centre, then picks the users or groups concerned. Companies that had already accepted Anthropic's separate terms have to do it again. This setting is one of those we review in our article on AI governance inside companies.
What Microsoft Copilot does better than other assistants
Copilot wins on one precise ground, grounding in your company data. Finding a decision made in a Teams thread six months ago. Drafting a reply that already knows the history of the case. Summarising a meeting and pulling out actions with the right names attached. No general assistant does that without heavy integration.
In Excel, the COPILOT function is written inside a cell like any formula. You can classify verbatims, extract information from free text, normalise product labels. I covered that use in our article on AI inside Excel.
The tool map I shared on LinkedIn in January 2026 sorts each product by the need it answers, from long-form reasoning to visual generation. Copilot answers a need that map does not cover, access to your own documents.
The full guide we publish, Microsoft Copilot and its seven use cases, walks through what that looks like app by app.
What Microsoft Copilot cannot do
An honest review names the limits too. Three of them come back on every engagement.
- Long-form writing. Across a multi-page document, end-to-end coherence stays better elsewhere. Our teams switch to another model as soon as the deliverable runs past a few paragraphs.
- Sourced web research. Copilot cites external sources rarely and poorly. On the investment fund we equipped, we added Perplexity Enterprise alongside it for exactly that reason.
- Automation that runs with nobody watching. Copilot waits for a human to trigger it. A process that has to run overnight, at volume, belongs to a different toolset.
That third limit is the one that costs the most when it gets ignored. Our comparison of workflows, assistants and agents draws the line, and I walk through it on video below.
A fourth limit comes from your own files. Copilot sees whatever the user is allowed to see. If your SharePoint permissions have been drifting for ten years, it will expose them within the first week. The tool behaves as designed, and cleaning up those rights becomes a project to run before rollout.
What we learned equipping more than a hundred people
Tandem deployed Microsoft Copilot and Perplexity Enterprise at a European private equity fund, for more than a hundred people. The fund runs several strategies in parallel and follows more than fifty portfolio companies. The case study is published here.
Three things made the difference, and none of them is technical.
- Training by level. Sessions of four to five people, executive committee included. Getting started, building specialised assistants, first agents.
- Agents by function. Fifteen to twenty agents and specialised skills, covering investment, legal, non-financial topics and human resources.
- Voluntary adoption. No usage mandate. Usage tracking serves to tune the agents, never to monitor the teams.
Our goal was to put AI in the hands of every team, with method. Working with Tandem let us move fast, within a controlled framework.

The same lesson shows up in my newsletter edition on AI return on investment. One hour saved per month already pays for the licence. Provided somebody shows the teams how to save that hour.
How much time does Microsoft Copilot really save?
The most solid public figures come from the British public sector, because they are published in full, method and limitations included. Vendor figures remain vendor figures.
The UK Department for Work and Pensions evaluated a trial run with 3,549 staff, from October 2024 to March 2025. Its statistical model estimates an average saving of 19 minutes a day across eight routine tasks, and 90 % of participants say they saved time. The report flags its own limitations, selection bias and omitted variables.
A separate cross-government British experiment, run on a different scope, lands at 26 minutes a day. Two studies, two methods, one shared order of magnitude. Between twenty minutes and half an hour per day per seat.
On the corporate side, Atos announced in June 2026 the rollout of Copilot to 56,000 employees across 54 countries, through the Microsoft 365 E7 bundle (Silicon, June 2026). Its digital officer describes it as the group's most significant technology investment in a generation.
Twenty minutes a day set against the cost of a French seat comfortably clears 26 euros a month. On one condition, that those twenty minutes genuinely exist in your company. On our engagements, the gap between trained teams and the rest stays the single biggest factor. That gap is exactly what our AI audit measures.
Should you buy Microsoft Copilot in 2026?
Yes, if three conditions hold. Your teams genuinely work inside Microsoft 365 every day. You budget training at the same level as licences. And somebody owns the topic internally, with dedicated time.
No, if you are looking for the best assistant on the market across every category. On raw writing and reasoning quality, other models keep a visible edge. Our panorama of AI assistants and our Claude versus ChatGPT comparison for business cover that question in detail.
My practical advice fits in one line. Equip a pilot team, train it properly, measure, then extend. That is exactly what our Microsoft Copilot training frames, and what we extend afterwards with our tailor-made AI copilots when the need outgrows what the tool covers.
