Microsoft Copilot in Plain English: What It Actually Does and Whether It Is Worth It

Everyone is talking about Microsoft Copilot. But what does it actually do?

If you use Microsoft 365 – Outlook, Word, Excel, Teams – then Microsoft Copilot is the AI assistant that sits inside all of those applications. Think of it as a very capable colleague who has read every document you have ever written, attended every meeting you have had, and can be asked to help with almost anything.

Here is what it does in practice, without the marketing language.

In Outlook

Copilot reads your emails. When you open a long email chain that has been going back and forth for days, Copilot can summarise the whole thing in seconds and tell you what has been agreed, what is outstanding, and what needs a response. When you need to reply to a difficult email, you can ask Copilot to draft a response – professionally worded, the right length, the right tone – and then edit it before sending. For people who deal with high volumes of email, this is where Copilot pays for itself fastest.

In Teams

This is the one that gets the most immediate reaction from business owners. Copilot attends your Teams meetings and, when the meeting ends, produces a full summary: what was discussed, what was decided, and who is doing what by when. It is accurate, it is ready within minutes of the meeting finishing, and it can be shared with anyone who missed the call.

For management teams and project meetings, the value is obvious. No more chasing minutes. No more ‘I thought you were doing that’. A clear record of every decision.

In Word

You provide a brief – a few bullet points about what you need – and Copilot writes a first draft. A client proposal, a policy document, a project update report. The draft will not be perfect and it should always be reviewed, but a 70% first draft that takes two minutes to produce instead of two hours changes how much you can get done. Copilot also rewrites existing documents: shorter, clearer, more formal or less formal depending on what you need.

In Excel

Copilot analyses data. You can ask it questions in plain English: ‘Which product line had the highest margin last quarter?’, ‘Show me a chart of revenue by month’, ‘Flag any rows where the cost exceeds the budget’. For finance teams, operations managers and anyone who spends time building reports from spreadsheet data, this is a significant time saver.

What about Copilot Chat?

Copilot Chat is the cross-application assistant. It can search across your emails, documents, Teams messages and calendar to answer questions: ‘What did we agree with ABC Ltd last month?’, ‘Find me the latest version of the Q3 report’, ‘Summarise everything I have from the Johnson project’. It works across all your Microsoft 365 data and is particularly useful for people who deal with lots of different clients or projects.

Is it worth it?

For most businesses, yes – but with an important caveat. Copilot is not a switch you flip and everyone immediately becomes more productive. It requires the right configuration, a proper introduction to the team, and a structured period of adoption to embed it into daily workflows. Businesses that buy the licence and do nothing else typically see low usage and question the investment.

Businesses that deploy it properly – with governance configuration, staff training, and an adoption programme – see consistent time savings across their team. Microsoft’s own research puts the average email time saving at over an hour per day per user. At almost any salary level, that makes the licence cost straightforward to justify.

The calculation is simple: if a member of staff at a £35,000 salary reclaims two hours per week, that is over £3,500 per year in productive time returned. The Copilot licence costs a fraction of that.
