Microsoft shipped another month of Copilot updates. For most UK SMEs the bigger opportunity is the capability they already licence and have never switched on. Here is what changed, what the roundups get wrong, and what to fix first.
Microsoft shipped another month of Copilot changes in August 2026. For most UK SMEs, the right response is not to get excited about any of it. It is to go and switch on what you bought last year.
Microsoft 365 Copilot lists at £23.10 per user per month on an annual commitment, excluding VAT. That fee buys the whole toolbox. Most businesses we sit down with are using a fraction of it, and the fraction they use is usually "summarise this email thread". Meanwhile another release lands, the feature list gets longer, and the gap between what you pay for and what your people actually do widens.
So here is the August 2026 roundup, followed by the part that matters more: what to do about the capability already sitting idle in your tenant.
What changed in Microsoft 365 Copilot in August 2026?
The theme was agents, branding controls and file-level governance, spread across the apps your team already opens every day.
In Microsoft Copilot Chat, you can now select Add and manage sources next to the compose box, then Add capabilities, to pull in tools like Research a topic, Analyze data, Write a document, Build a worksheet and Design a presentation (Microsoft support). There is also a model picker, so users can choose between OpenAI GPT models and Anthropic's Claude models, where an administrator has enabled them (Microsoft 365 blog).
The app-by-app picture:
- Word: Edit with Copilot respects Track Changes, so you can see and review a rewrite rather than having it silently replace your text (Microsoft support).
- PowerPoint: brand kits apply approved logos, colours, fonts and templates to Copilot-generated decks, managed centrally by a brand owner (Microsoft support). Custom skills can be built in the app or added by uploading a SKILL.md file (Microsoft support). You can also generate a new deck from an existing presentation, keeping its theme and layouts (Microsoft support).
- Excel: personalisation lets you set formatting and formula preferences once, alongside a library of sample finance skills (Microsoft 365 blog). Copilot can also analyse Power BI reports and insert editable tables and charts from that data (Microsoft support).
- Microsoft Teams: a Meeting Recaps app gathers your recorded meetings into one list, each with its recording, transcript, AI summary, files and follow-ups (Microsoft support).
- SharePoint: AI audio overviews now cover documents and news posts, in a summary or podcast style (Microsoft support). Structured document generation turns a Word template into a form-driven process that produces consistent, governed documents into a library (Microsoft Learn).
- Copilot Notebooks: a simpler interface, OneNote integration, and a wider set of reference file types including .txt and .rtf (Microsoft support).
- Copilot Cowork: you can upload your own plugin package and your own skill file (Microsoft Learn), and automations now run either on a schedule or when an event happens (Microsoft Learn).
That is a genuinely useful month. It is also, for most SMEs, completely beside the point.
Why doesn't a bigger feature list change anything?
Because the constraint was never features. It is that nobody in the business owns getting value out of the ones you already have.
Do the arithmetic on your own licence count. Twenty-five users on Microsoft 365 Copilot is roughly £6,930 a year before VAT. That is a real line in the budget, and it is being spent whether or not anyone opens the model picker. Unused capability is not neutral. It is a cost with no return against it, and it quietly trains people to think AI at work is underwhelming.
The evidence says your staff have not gone off AI. They have gone somewhere else. Microsoft research published in October 2025 found that 71% of UK employees have used unapproved consumer AI tools at work, and 51% do so every week. Research from SAP and Oxford Economics in February 2026 put it at 68% of UK organisations reporting staff use unapproved AI tools at least occasionally. Your people are pasting company information into something. The question is whether it is the tool you pay for, govern and can audit, or the one they found themselves. If that pattern is new to you, our guide to what shadow IT is and how it affects your business covers the wider version of the same problem.
What idle Copilot licences look like in practice
One finance team we work with had Copilot licences for months and was still doing the same manual spreadsheet work it had always done. Nothing was broken. No ticket was ever raised. Nobody had shown them what the tool could actually do inside their own workbooks, so they carried on as before and the licences ticked over in the background.
We ran a working session on their real month-end files. Not a demo tenant, not sample data, their spreadsheets. Usage changed after that, and it changed because someone finally connected a specific feature to a specific job they were already doing.
That is the whole intervention. It is not a project, and it does not need a business case. It needs an afternoon and someone who knows which features map to which tasks.
Where the video oversimplifies
Feature roundups are recorded in clean demo tenants, and a few claims in this one do not survive contact with Microsoft's own documentation. Worth knowing before you promise something to your team:
- Copilot in Word does not add comments. Microsoft's documentation states that Edit with Copilot cannot add or modify comments in a Word document at this time, and cannot accept or reject tracked changes. It respects Track Changes. It does not manage them.
- Copilot Notebooks does not take markdown files. The supported reference types are .docx, .pptx, .xlsx, .pdf, .loop, .page, .txt, .rtf and OneNote pages. There is no .md on that list.
- Power BI is not a default source. It is a source you attach when you want it, not something switched on for you.
- Roadmap dates move. Several capabilities in the video were described with a rollout window. Plan around what is documented and available in your tenant today, not around a date on a video.
None of this makes the roundup wrong. It does mean you should check the official page before you build a process on top of a feature.
The four updates worth an actual decision
Four of these changes are governance controls wearing productivity clothing, and they deserve a decision from someone senior rather than a shrug.
Excel workbook rules. Rules live in a .Rules worksheet that travels with the workbook, so sharing the file shares the rules (Microsoft support). For any team where six analysts have six versions of the same model, that is a standardisation tool, not a convenience feature.
PowerPoint brand kits. Centrally managed brand assets stop AI-generated decks going out looking like they were made by six different companies. Someone needs to own the kit.
The Copilot Control System. This is where agents, connectors, data access and agent lifecycle policies are governed from the Microsoft 365 admin centre (Microsoft Learn). If you have never opened it, you do not currently know what your users can reach.
Work IQ. This is the layer that grounds Copilot and its agents in your enterprise work data: email, chats, meetings and files, permission-trimmed to the individual user (Microsoft Learn). Read that last part again, because it is the whole risk model.
Do this before you switch on anything else
Copilot is permission-trimmed, which sounds reassuring until you remember what it means. It will surface anything a user can already reach. If your SharePoint and OneDrive permissions have drifted over five years of "just share it with everyone for now", Copilot does not create that problem. It makes it instantly, cheerfully discoverable by the person least likely to keep quiet about it.
So the action this week is not enabling more features. It is this:
- Run a permissions and oversharing review across SharePoint and OneDrive. Find the sites shared with "Everyone except external users" and fix them.
- Open the Copilot Control System and write down which agents, connectors and models are currently enabled, and who approved each one.
- Ask your staff, with no blame attached, which AI tools they already use. You need the honest answer more than you need the tidy one.
- Pick one team and one repeatable task. Run a session on their real files. Measure the time it saves.
- Then, and only then, turn on the next thing.
If you want the licensing and governance detail behind step two, we cover it in Microsoft Copilot Chat: the agents most UK SMEs aren't using, and if you are still deciding which Microsoft AI product fits which job, our comparison of Copilot, Cowork, Scout and Studio is the shorter route.
What this means for you
The pace of Copilot releases is not going to slow down, and trying to keep up with it feature by feature is a losing game for a business with other things to do. The businesses getting value are not the ones reading every roundup. They are the ones who picked two or three jobs their people do every week, made Copilot genuinely good at those, sorted the permissions underneath, and then ignored the noise until something relevant landed.
You are already paying for the toolbox. The work is opening it properly. That is where our AI consultancy team spends most of its time, usually alongside a permissions and compliance tidy-up that should have happened years earlier. If you would rather start with what you already own than buy something new, book a discovery call and we will look at your tenant with you.
