Someone in your business has asked about Microsoft Copilot. Maybe a director saw a demo and wants to know why you don't have it yet. Maybe someone on your team is already using it on a personal account and asking when it's coming to their work laptop. Either way, you need an answer that holds up, not a marketing summary.
If you're the only person who can explain what Copilot does and what it needs from your Microsoft 365 setup, you're not only running IT, but you're also carrying the risk of getting this wrong on your own. This guide covers the full picture: what Copilot is, how it works inside the Microsoft 365 apps your business already runs, what it costs to licence, what your tenant needs before you switch it on, and what a rollout looks like.
This is where a lot of small IT teams get caught out. If you're already stretched across device requests, support tickets and everything else that lands on your desk, a director asking about Copilot arrives as one more urgent thing on top of the pile. Answering it properly, rather than promising to look into it and letting it drop, is what keeps a decision like this in your hands rather than being made around you.
What is Microsoft Copilot
Microsoft Copilot is an AI assistant built into Microsoft 365. It uses generative AI, technology that drafts new text, summaries and suggestions rather than only retrieving existing information, and applies it inside the Microsoft 365 apps your business already runs: Word, Excel, Outlook, Teams and others. It works from your own documents, emails, spreadsheets and chats, within the permissions already set on each person's account.
In plain terms, Copilot can draft, summarise, analyse content and answer questions using content that already exists in your Microsoft 365 environment. People spend less time producing a first draft and more time on the judgement calls a person still needs to make.
| App | What Copilot does |
|---|---|
| Word | Drafts, rewrites and summarises documents from a prompt or an existing file. |
| Excel | Explains formulas, spots patterns in data, and builds analysis from a plain English request. |
| Outlook | Summarises long email threads and drafts replies in an appropriate tone. |
| Teams | Summarises meetings, captures action points, and catches people up on discussions they missed. |
How Copilot works, and what it doesn't do
Two things matter more than any feature list when you're explaining this upward. First, Copilot only sees what the person using it can already see. It doesn't grant new access to files, mailboxes or Teams channels; it works within the permissions that already exist. Second, Copilot works from your current content. It drafts a report from your numbers; it doesn't invent the numbers. Someone still needs to check the output before it goes anywhere near a customer or the board.
This matters because most Copilot objections come down to trust, not the tool itself: whether it will expose something it shouldn't, and whether the output can be relied on without checking. Both are fair questions, and both have straightforward answers once your tenant and your people are ready, covered below.
What Microsoft Copilot is used for, day to day
Copilot's value shows up in ordinary, repeated tasks rather than anything dramatic. None of the examples below need a specialist skill to get started with, which is exactly why untrained use spreads quickly and unevenly across a business once one person finds something that works for them.
Reconciling figures across spreadsheets, drafting board packs from raw data, and summarising long supplier contracts before a renewal conversation.
Turning meeting notes into an action list and drafting standard reports without starting from a blank page each time.
Drafting first-pass responses to routine emails and preparing a meeting brief from CRM notes and calendar history.
Summarising long policy documents, drafting standard communications, and turning a rough set of notes into something presentable in minutes rather than an afternoon.
Licensing: what to check before you ask for budget
Microsoft sets and changes Copilot licensing on its own schedule, so a specific figure printed here would be out of date by the time you read it. Check Microsoft's current pricing directly or ask TSG for a live quote against your specific Microsoft 365 estate, before you take a number to your board.
What you can plan around now is the shape of it. Copilot is sold as an add-on licence on top of qualifying Microsoft 365 plans, priced per user. That means the real budgeting question isn't the headline price, it's how many people need it.
Most of the licence-cost objections in Copilot conversations come from not the price itself, but paying for seats nobody opens. A short usage review, working out who genuinely needs drafting, summarising and analysis support in their day-to-day work, before you licence anyone, is cheaper than discovering twelve months of spend nobody used. TSG's Cloud Care Licensing and Microsoft 365 optimisation service is built for this, keeping your licence estate matched to who's using what, Copilot included, rather than running on assumptions.
Some Microsoft 365 plans already include a limited version of Copilot's capability, while the fuller experience across every app sits on the add-on licence described above. Which one applies to your current agreement is worth confirming before you assume you need to buy anything new; it's a five-minute check against your existing plan, not a guess.
Is your Microsoft tenant ready for Copilot?
Copilot works from whatever is already in your tenant, the Microsoft 365 environment holding your organisation's users, mailboxes, files and permissions. If that environment is untidy with old shared drives that nobody's reviewed in years, files still open to people who've since left the business, duplicate and out-of-date documents scattered everywhere, Copilot will surface all of it as readily as the content you want it using. That's not a Copilot problem. It's a data problem Copilot makes visible faster than anyone expects.
A proper readiness check looks at three things before anything gets switched on.
Who can see what, and whether that still matches who should see it.
Whether the content Copilot will draw from is current, accurate and not duplicated across five different folders.
Whether your Microsoft 365 plans qualify for Copilot, and whether baseline security settings, multi-factor authentication among them, are already in place.
TSG's Copilot Readiness Assessment checks exactly this ground, your tenant and your data, before you commit to licences. It turns ‘we're not sure our data is ready for this’ from a worry into an answer.
What a sensible Copilot rollout requires
Licensing Copilot is the easy part. Getting it used properly, so the spend is justified rather than questioned at the next budget review, is where most rollouts succeed or fail. Two things matter beyond the licence.
People need to know what to ask Copilot and how to check what it gives back. Left to work it out alone, most people either stop after a couple of tries or trust the output more than they should. A short, structured introduction built around the tasks your teams do changes that; a generic AI seminar covering features nobody in your business will use does not.
Someone needs to own the rules: what Copilot should and shouldn't be used for, how outputs get checked before they reach a customer or the board, and what happens when it gets something wrong. This doesn't need a lengthy policy document. It needs a short, clear set of expectations everyone on the team has read.
TSG's AI programme is built for the training side: structured Copilot training delivered to small groups of colleagues, covering tasks people in your business genuinely do rather than a feature tour. For teams that want to explore the wider Microsoft toolset first, TSG Academy is a free, self-serve training resource for TSG's Microsoft 365 customers; it's a general resource rather than Copilot-specific, but a reasonable starting point if training budget or time is tight.
Taking this to the board
You don't need a full business case for every seat before you say anything upward. You need three things ready: a clear answer to what Copilot does, a straight number on what it will cost once you know how many people genuinely need it, and evidence that your tenant and your data can support it. That's a rollout plan, not a sales pitch, and it holds up to scrutiny because none of it is guesswork.
Copilot isn't complicated to explain once the marketing is stripped out. It's a drafting and analysis assistant that works inside the Microsoft 365 apps your business already pays for, built from your own data, inside your existing permissions. The work is in checking your tenant is ready, training people properly, and keeping an eye on who's using what you're paying for. Get those three right and Copilot earns its licence cost. Skip them and it's an expensive feature nobody opens.

Take the assessmentFrequently asked questions
What is Microsoft Copilot used for?
Drafting and rewriting documents, summarising long emails and meetings, building analysis in Excel from a plain English request, and catching people up on discussions they missed in Teams. It works from your own Microsoft 365 content, inside each person's existing permissions, so the output still needs a person to check it before it's used.
How much does Microsoft Copilot cost?
Microsoft sets and changes Copilot pricing, so any figure here would date quickly. It's sold as an add-on licence on top of qualifying Microsoft 365 plans, priced per user. Check Microsoft's current pricing directly or ask TSG for a quote against your specific Microsoft 365 setup before budgeting.
Do I need training to use Microsoft Copilot effectively?
Not to switch it on, but yes to get real value from it. Most people either stop using Copilot or trust its output more than they should without a short, structured introduction to what to ask it and how to check what it gives back. Training is what turns a licence into daily use.
Is Microsoft Copilot the same as ChatGPT?
Not quite. It uses the same generative AI model in the background, but Copilot is built into Microsoft 365 apps like Word and Outlook and works within your business's existing Microsoft permissions and data boundaries. A consumer chatbot doesn't have that context. Copilot drafts from your own documents and emails; ChatGPT doesn't know your business exists.
Which Microsoft 365 apps include Copilot?
Word, Excel, Outlook and Teams are the core four, alongside PowerPoint and other Microsoft 365 apps depending on your licence. Each works differently: drafting in Word, formula and data help in Excel, email summaries in Outlook, and meeting summaries in Teams.
