What can Copilot Cowork do? Real use cases

Turning a complex project into a proposal deck

The first test was creating a proposal deck for a fairly detailed project. The kind of work where the challenge isn’t just the content, it’s how you present it clearly so a client can actually follow what you’re proposing.

Rather than preparing a clean brief for it, we used the same materials we were already working from at the time, such as pricing and scope planning, alongside notes on the project itself, and asked Copilot Cowork to turn that into a presentation.

What stood out straight away was the structure; it organised the content into a narrative that made sense from a client perspective. The flow worked. It moved logically from context to challenges, into the proposed approach, then into delivery and next steps. That’s the part that usually takes time, and it handled it well.

That said, it wasn’t something we could send as-is. Every slide needed checking. Wording needed tightening, a few ideas needed expanding, and in a couple of places we re-ordered things or added slides so it reflected how we wanted to present the work. But in this case, it was easier to edit something which already existed than to start from scratch.

The branding challenge

The bigger issue was branding. On the first version, the colours were close but not consistent enough, and the fonts were wrong. That’s not surprising when you think about how PowerPoint works, but it can catch people out.

The improvement came when we created a proper PowerPoint theme and supplied that alongside a branded example deck and brand guidelines document. Once those were in place, the output improved noticeably. It still needed editing, but it was much closer to what we wanted and saved formatting time.

A small but useful workaround

We also tested if it was possible to correct fonts inside PowerPoint using Copilot in that app. It is! So, if you can’t get it to apply your branding the first time, you may be able to correct it inside PowerPoint just by telling Copilot what you want. That saved a lot of time.

By the end of the process, the deck was finished, refined, and ready to be used. The key difference was that we didn’t have to build the structure from a blank template. By already working with a narrative that made sense, we were able to see how to improve it from there faster.

An observation for the future

If you’re planning to use Copilot Cowork for presentations regularly, we would strongly advise giving it a few examples of uniquely designed presentations in your company branding for its reference.

If you look at other examples of presentations made using Cowork, the layout it produces is fairly consistent. The structure works, but it can feel quite generic, as if it’s drawing from a limited set of presentation styles rather than creating something completely new each time.

That doesn’t make it unusable, but it does change how you approach it. If you rely on it as-is, there’s a risk that your presentations start to look similar to everyone else using the same tools.

In practice, it makes more sense to treat what it creates as a first draft. You can then go in, adjust layouts, apply your own background styles, and bring it back in line with your branding. How much that matters will depend on how important standing out is to your business, but it’s worth being aware of.

Preparing for a meeting using real project context

The second test was simpler and we used one of Cowork’s built-in “prepare for a meeting” prompts and adjusted it to match how we actually work.

Instead of relying on whatever it could pull from the calendar, we uploaded a project brief and a status tracker so it could understand the context and the current state of the work. Then we added a few details it wouldn’t have access to, things that had been discussed over the phone or shared outside Microsoft 365.

What it produced was a clear, structured agenda. It wasn’t generic. It reflected what actually needed to be discussed, based on the deliverables and progress. There wasn’t much to change.

Taking its time

It offered to turn the agenda into a Word document, and while that’s exactly what it’s designed to do, in that moment it was quicker to copy the text and paste it into Word.

That’s where the difference between “automation” and “workflow” becomes obvious. Cowork is designed to run tasks in the background. It’s something you set going and come back to. If you need something instantly after reviewing it, there are still moments where manual is faster.

There’s also a practical limitation that shows up here. It can’t see anything that sits outside your Microsoft 365 environment without adding additional plug-ins. If a client has shared something over WhatsApp or mentioned something in conversation, that context doesn’t exist for Copilot unless you add it yourself. Once you do, it uses it well, but it won’t guess it.

This use case is probably the most transferable. Whether you’re in sales, operations, or customer service, turning scattered project information into a clear meeting plan is something that comes up constantly. It handles that well, as long as you give it what it needs.

Copilot Cowork vs Researcher agent

The third test focused on company research, but more specifically on comparing how Copilot Cowork performs against the Researcher agent when you’re trying to build a structured view of a business.

The goal wasn’t just to get a quick overview. It was to see how each tool handles a more detailed task; understanding what a company does, how it positions itself, and how much insight you can gather without having to manually piece everything together.

Using Copilot Cowork for this produced a detailed, structured output. It worked through the company’s website content, pulled together key points, and presented everything in a way that felt more like a consultant’s brief. It also made it clear where information couldn’t be found, which is useful when accuracy matters. The trade-off is that it can be slower, heavier, and sometimes too detailed for quick repeatable scans.

Running a similar task through the Researcher agent gave a noticeably different result. The response was faster and more concise, and better for rapid orientation across multiple companies. It is useful when you want a quick synthesis of target markets, positioning, differentiators, and broader signals without wading through a long report. However, the faster response comes with less granularity and slightly more risk of overreach, where Researcher may infer from live or partial signals while Cowork is more cautious and will simply note when data is unavailable.

We would conclude that Copilot Cowork is better suited to situations where you need a more structured, reliable picture, something you can build on. Researcher is useful for quickly scanning or getting initial context, but it may still need closer review.

A tip for using Cowork for research

There are still limitations to be aware of. Some sources aren’t always accessible depending on how the site loads or whether interaction is required. In those cases, the most effective approach was to build a simple instruction into the process – if something couldn’t be accessed, to pause and ask for manual input, such as a screenshot, or a verbal description. That allowed the research to continue without losing context.

What this test showed is that Copilot Cowork can save a significant amount of time at the early stages of research, particularly when you’re trying to structure your thinking. It doesn’t replace the need to check sources or apply judgement, but it does remove a lot of the initial groundwork.

What this tells you about using Copilot Cowork

Across all three tests, we were able to use Cowork to complete a lot of the early stages to get us moving forward faster. Starting a proposal, structuring a meeting, or figuring out how to approach research all involve a moment where you have to decide what shape the work should take. That’s where we feel Cowork is strongest. It gives you something to react to, edit, and refine when the alternative is a blank page.

The other thing worth knowing is that it improves significantly when you provide more detailed instructions, files and context. In order to know how to do that, you need to use the tool, discover its limitations and build with those in mind. If you don’t, it falls back to something more generic.

Conclusion: What can Copilot Cowork do?

It can take information from your company files using WorkIQ, or files you provide, and your prompts, organise it into something structured, and produce outputs like documents, presentations, and meeting plans. When it works well, it can save hours of time at the point where you would normally be starting from nothing.

What it doesn’t do is replace the thinking behind the work. It supports it. When you treat it that way, it becomes a useful part of how you work rather than something you test once and leave behind.
