The Beginner’s Guide to Microsoft Copilot: What It Actually Does (and Doesn’t Do)

If you use Microsoft 365 apps or your business uses a Microsoft 365 for Business plan, you've heard of Copilot. But it can be hard to keep the different "forms" of Copilot straight. Here are the three that really need distinction:

• Microsoft Copilot: free chat for anyone, including consumers. It can be reached via a web browser, or through the standalone Copilot app on Windows and mobile
• Microsoft Copilot Chat: included in Microsoft Business plans. It's like Microsoft Copilot, but prompts and responses are not used to train Microsoft's models and data stays within your organization's M365 environment boundary. It can also be accessed online (signed in with your work account), or through the Copilot app on Windows and mobile
• Microsoft 365 Copilot Business: add-on licenses for users that integrate Copilot fully into M365 apps and company data. It shows up right inside Word, Excel, PowerPoint, Outlook, and Teams, in the dedicated Microsoft 365 Copilot app, or accessible online. Licenses can be purchased for individual users, not the whole organization. It can also be accessed online (signed in with your work account), or through Copilot app on Windows and mobile

In this guide, we cover what Copilot actually does, what it costs, and whether Microsoft 365 Copilot Business makes sense for your company.

What Is Microsoft 365 Copilot Business?

This guide covers three different services that use the Copilot name, but the one most business owners need to understand is Microsoft 365 Copilot Business, the paid version that lives directly inside the Microsoft 365 apps people already use: Word, Excel, PowerPoint, Outlook, and Teams.

The key difference between Microsoft 365 Copilot Business and a general chatbot is that the former has access to your organization's data, like emails, documents, chats, calendars. It also keeps the privacy and access settings already set in your M365 environment. Someone only sees what they already have permission to see. It's grounded in a company's actual work context and not just generic internet knowledge.

The Three Versions of Copilot: Consumer vs. Included vs. Paid Add-On

Here's the part that confuses a lot of people (and us at SpireTech sometimes too!). There are two different items using the Copilot name in M365 Business accounts, but they are not the same product.

Here's how the three forms of Copilot stack up side by side:

Microsoft Copilot

Microsoft Copilot is Microsoft's AI tool that is free to use for everyone. It's the tool available to consumers. It can answer any question you might ask an AI tool, and it generates its answer from its training data, the web, and other sources.

Unlike Microsoft Copilot Chat and Microsoft 365 Copilot Business, however, your conversations with Copilot will be used for training data by default. You need to manually opt out if you do not want your data to be used in LLM training.

Here's how to find that setting and opt out:

• Mobile App: Go to Settings > Account > Privacy > Model training and turn the setting off.
• Web/Account: Adjust your privacy settings directly through the Microsoft Copilot Privacy Controls or your account configuration page

That's important to know if you do not want your data to be exfiltrated. Anything you enter has the potential to pop up in a future chat for someone else. That's why SpireTech really emphasizes data security in AI use and disallows use of free AI tools for our employees. Data privacy remains a top priority to us and our clients.

Microsoft Copilot Chat

Included in most Microsoft 365 Business plans now. This is a free, web-based Copilot Chat. It's useful for general questions, brainstorming, and basic drafting.

It is able to draft documents, spreadsheets, and presentations for you but cannot iterate on that draft after it has been delivered to you. To iterate, Copilot will create and deliver a new version with every edit. Conversely, with the additional Copilot license, Copilot would be able to iterate within the M365 apps directly and make changes from the Copilot conversation, no new drafts required.

In Microsoft Copilot Chat, a user is also able to upload files, screenshots, documents, and more into the conversation with Copilot. However, unlike as with Microsoft 365 Copilot Business, it will not be able to find or have any additional context from your organization; you will need to upload every file you want it to respond to, every time.

Microsoft Copilot Chat is limited in its abilities and cannot:

• Open documents from SharePoint on its own
• Edit a file stored in OneDrive
• Search Teams messages
• Read Outlook emails
• Review calendars
• See CRM, tickets, or business data
• Update an existing SharePoint document in place

It is important to note that because it is tied to a business account, prompts and responses are not exfiltrated and used for model training. This is what separates it from "Microsoft Copilot," the general free chatbot. Copilot Chat has very limited access to an organization's data. For example, in Outlook, it can answer basic questions about a person's own inbox and calendar.

Work Mode

There is a "Work mode" toggle available in Microsoft Copilot Chat that can pull in some company data you have permission to see. But that deeper access is metered and billed pay-per-use, not included outright. However, pay-as-you-go billing is off by default and has to be deliberately turned on by an admin (tied to an Azure subscription), and the cost exposure is somewhat open-ended rather than a predictable per-user fee.

"Work mode" is a smarter, safer version of a general chatbot: useful, with occasional glimpses into your own data, but not deeply or continuously connected to your business. The "Work mode" is useful for businesses who don't need add-on Microsoft 365 Copilot Business licenses but occasionally need company data access for some tasks. Pricing can be confusing, so make sure you and your tech team understand what you're paying, and for what.

Microsoft 365 Copilot Business

This is the paid add-on license to Microsoft Business subscriptions, added per-user. It provides deep integration of Copilot with M365 apps: Word, Excel, PowerPoint, Outlook, and Teams. Microsoft 365 Copilot Business also continuously stays connected to company data and context.

As with Microsoft Copilot Chat, users can generate documents, spreadsheets, presentations, and more from within the conversation. More importantly, you can iterate in that same conversation. Without the additional Copilot license, Copilot has to generate a new version of everything with every edit or change the user requests.

With Microsoft 365 Copilot Business, you can upload files into the conversation to give Copilot that additional context. It can also fetch files and documents from within your organization data and business context without you needing to upload it. You do not even need to reference a particular document for any one question; Microsoft 365 Copilot Business will get its information from company data. It's like talking to a coworker who already understands the business, functions, and documents you're working with.

The short version: Copilot Chat that is included in M365 Business accounts gives you occasional, limited access to your own data. The paid Microsoft 365 Copilot Business is always grounded in your organization's work. When people say Copilot "changed how their team works," they almost always mean the paid version. We'll dig deeper into the differences in a future post, but that distinction is the one to keep in mind for everything below.

How to Know which Copilot You're Using

With all of these different forms of Copilot, it can be hard to know which one you're using for sure. Luckily there are a couple easy ways to check. The easiest way to check for all three is with visual cues. Depending on what kind of account and license you have, your name and account will show up differently on the left bottom corner of the Microsoft app and with Copilot online.

Microsoft Copilot: for Consumers

The visual cues for this one are actually the absence of license names. It can also look differently depending on if you're:

• Signed in with a personal Microsoft account
• With no Microsoft 365 business tenant
• With no Microsoft 365 admin center

You will not see a Copilot license label beneath the account name. What is looks like will vary depending on your subscription and whether or not you're signed into Microsoft, but here is one example of what Microsoft Copilot will look like for consumers:

For people using Microsoft Copilot for consumers, it is also lacking the toggles that Microsoft Copilot Chat (toggle says "Auto") and Microsoft 365 Copilot Business (toggle will say, "Work IQ" and "Auto").

Microsoft Copilot Chat: Included in Most Microsoft 365 Business Subscriptions

If you are using Copilot with a work or school account without an additional Copilot license, you're using Microsoft Copilot Chat. You can find this on the bottom left of the Copilot app interface. It will say your name, then "Copilot Chat (Basic)" underneath. Your toggle will say Auto but not have a Work IQ option and there will be a "Work" or "School" badge to the left of your name.

Here's an example of how your account information might shop up in the Copilot interface:

Microsoft 365 Copilot Business: M365 Business Account + the Additional Copilot License

If you're using Copilot with an M365 Business account with the additional Copilot license, the bottom left of the Copilot app will have your name, a "Work" or "School" badge to the left of your name, then "M365 Copilot (Premium)" underneath. The toggles above the chat start will also have "Work IQ."

Here's an example of how your account information might shop up in the Copilot interface:

What Microsoft 365 Copilot Business Can Do

As previously stated, the add-on licenses of Microsoft 365 Copilot Business buys you native integration into the M365 apps you already use. Here are some examples of its great use cases:

In Outlook: summarize long threads to catch up on a 40-message chain in a sentence or two, draft replies built from the conversation's actual context, pull action items and commitments out of a messy chain, and flag which emails need a response. Because it reads a person's inbox and calendar, it can also answer questions like, "When did I last hear from this client?" without the person needing to search.

In Teams: summarize meetings missed, surface key decisions and action items with the assigned names attached, answer questions about what was discussed without scrolling back through hundreds of messages, and catch someone up on a Teams channel after time away. If someone asks, "What was decided about the budget?", Copilot pulls the answer from the transcript.

In Word: create a first draft from an outline or from an existing document, rewrite sections in a different tone, condense long documents into key points, and pull in related material from files, so a proposal draft can reference the actual figures from a spreadsheet or the terms from a prior contract. Someone can check the accuracy of their writing against actual company documentation and keep everything consistent with what the business actually offers.

In Excel: suggest formulas and explain what they do, surface trends and outliers in data, help clean up messy spreadsheets, and answer plain-language questions about a table (like, "Which region grew fastest last quarter?") without someone needing to write the formula themselves (though learning Excel basics is still worth it).

In PowerPoint: generate slide decks from a Word document, suggest layouts, create speaker notes from slide content, and reformat or reorganize an existing deck. If someone hands it a proposal, Copilot can draft a client-ready presentation in minutes from the same source material.

What Microsoft 365 Copilot Business Gets You that Microsoft Copilot Chat Doesn't

Being plugged into and able to use company context is the major standout feature in Microsoft 365 Copilot Business. Having context changes a lot in the experience. It makes working with Copilot easier, more effective, and more impactful. Which may mean less time spent reviewing or researching, less monotonous work, and consistent information across departments.

That added company data and context is what makes Microsoft 365 Copilot Business consistent and consistently useful. Because Copilot can see across your Microsoft 365 environment, it connects the dots between apps: it can pull details from an email into a Word doc, or turn a document into a slide deck, without copying and pasting between them.

A general chatbot, including Copilot Chat, knows a lot about its training data, but next to nothing about your specific business. Its access to your organization's data is narrow and mostly limited to a few built-in exceptions, such as basic Outlook inbox questions. Ask it to draft a follow-up to a client, and it'll come back with a generic answer. It has no standing access to who the client is, what you promised them last week, or what the project actually is.

Microsoft 365 Copilot Business, however, does know all of that. The context already lives in your M365 enviornment, and it's just a matter of finding and utilizing it.

From a data security standpoint, Microsoft 365 Copilot Business also respects the permission and access boundaries that are already set. Copilot uses the data a given user can already open. The context is deep but stays scoped to each person's existing permissions.

Using Microsoft 365 Copilot Business also opens up deeper technical opportunities and more advanced tools. Copilot agents can handle specific repeatable tasks (like triaging a shared inbox or pulling weekly reports). Automated workflows connect steps across your apps or follow repeatable steps. In Copilot Studio, someone can build custom agents to do whatever specific, custom job your firm needs done. Copilot Cowork takes on complex, multi-step projects from start to finish. A few examples of what it can do are cleaning up and cross-referencing dozens of files or working a sales pipeline from research through follow-up. It's not for just answering a question or drafting a document. It should be noted that, while it is included with your Microsoft 365 Copilot license, it is billed separately based on usage.

The Bottom Line

The many forms of Copilot aren't magic, and Copilot isn't a replacement for skilled people doing thoughtful work. (In fact, check all outputs done by an AI. Never assume that it's right.) It's a tool that saves time on repetitive tasks, gets someone to a good starting point faster, and surfaces information they already have but might not remember.

The practical takeaway: if your company is already on Business Standard or Premium, adding Microsoft 365 Copilot Business is a straightforward license change and not a major overhaul. If your team spends real time each week summarizing threads, drafting from scratch, or hunting for information they already have access to, that's where this pays off.

Frequently Asked Questions

Q: Is Copilot included with my Microsoft 365 subscription? A: The free Copilot Chat is included with most Business plans, but its access to your organization's data is extremely limited. The version that works inside your apps and pulls deeply from your emails, files, and chats, Microsoft 365 Copilot Business, is a paid add-on.

Q: Do I need an Enterprise M365 plan to use Copilot? A: No. Microsoft 365 Copilot Business works with Business Basic, Business Standard, and Business Premium.

Q: Is Copilot a standalone app or website? A: Copilot is not just a standalone app or website; it can be accessed at copilot.microsoft.com and in its desktop app. However, Microsoft 365 Copilot Business also lives inside the apps you already use, like Word, Excel, PowerPoint, Outlook, and Teams.

Q: Can Copilot see data I don't have permission to access? A: No. Copilot respects your existing Microsoft 365 permissions. It only surfaces information you could already open yourself. That's also why a poorly configured environment produces poor results, Copilot inherits whatever mess is already there.

Q: Can Copilot make mistakes? A: Yes. Like any AI, Copilot can make mistakes or misinterpret context. It's a good starting off point, but always verify AI outputs. Review everything impactful before it goes out.

Q: Has Copilot Chat's availability changed recently? A: Yes. Microsoft has been changing what's included in the free tier. As of April 2026, Copilot Chat was removed from Word, Excel, PowerPoint, and OneNote, but only for organizations with 2,000 or more Microsoft 365 users. If your organization is smaller than that, you still have free Copilot Chat in those apps. It just runs under "standard access," meaning it can be slower or lower priority at peak times, with occasional prompts to upgrade.
