Microsoft 365 Copilot and Copilot Chat in daily work

0:00 Microsoft 365 Copilot

If your organisation runs on Outlook, Teams, Word and Excel, Copilot can take real hours out of your week. But only if you know which Copilot you are actually using, which workflows are worth it, and where its summaries go wrong. In this lecture you will learn exactly that, with examples from real office days.

0:24 Why this matters

Why does this matter? Because a large share of office work is catching up, drafting, summarising and reporting. Reading long threads, writing follow ups, turning meetings into actions. That is precisely what Copilot is built for. But there is a catch. When an AI meeting summary gets a decision wrong and you forward it to five people, the error travels fast and carries your name. So we will learn both the speed and the checking.

0:57 Which Copilot?

First, which Copilot are you using? Microsoft uses the name for several products. The consumer Copilot is for personal Microsoft accounts. Microsoft three six five Copilot Chat is a web grounded chat that comes at no extra cost with eligible business subscriptions when you sign in with your work account, and it is covered by enterprise data protection. And Microsoft three six five Copilot, the paid licence, works inside Word, Excel, PowerPoint, Outlook and Teams, grounded in your organisation's emails, files and meetings through Microsoft Graph, which Microsoft now calls Work IQ.

1:37 The analogy

Here is an analogy. Copilot Chat is like a very smart visitor to your office. Brilliant, but it only sees what you show it, plus the public web. Licensed Microsoft three six five Copilot is like a colleague with your building pass. It can open your emails, files and meetings, but only the doors you are already allowed to open. That is why permissions matter so much, which is the focus of the next lecture.

2:10 What else is included

The licensed product also includes reasoning agents. Researcher runs multi step research across your work data and the web. Analyst works through data like a data scientist. There are Copilot Notebooks and Pages for collecting and shaping work, and in twenty twenty six Microsoft added Copilot Cowork, an agentic experience that plans and carries out multi step tasks. Copilot also offers a choice of models, including models from OpenAI and Anthropic, under Microsoft's enterprise terms. Licensing and features change often, so your IT admin and Microsoft's documentation are the source of truth.

2:50 Simple example

Let's start simple. You return from a day off to a thirty message email thread. Ask Copilot in Outlook to summarise it with three headings, decisions, open questions, and what is being asked of me. In seconds you learn the supplier changed the delivery date, pricing is still open, and your manager needs your approval by Thursday. Then ask Copilot to draft a reply confirming the three next steps, under one hundred and twenty words, with T B C for anything unknown. You check it and send it yourself.

3:29 Workflows across apps

Across the other apps, a few prompts do most of the work. In Teams, what did we decide, list actions with owners and due dates. In Word, draft a proposal using these referenced files, with pricing marked T B C. In Excel, add a margin column and highlight rows under fifteen percent, or explain this formula. In PowerPoint, create a ten slide deck from this Word document using our template. Each one saves real time, and each one still needs your review.

4:05 Verification habits

Four verification habits. In meeting summaries, check whether something was agreed or merely proposed, because summaries tend to overstate consensus. Check owner names and dates against the attendee list. Spot check numbers against the workbook. And ask Copilot which files or emails it used, then open the important ones. These checks take a couple of minutes and protect your credibility.

4:31 Consent and transcription

Copilot in Teams meetings depends on transcription or recording. Always inform participants and follow company policy and local law, because consent rules differ between the UK, the EU, the UAE, Saudi Arabia, Pakistan and different US states. And avoid transcribing sensitive conversations, such as HR, legal or health discussions, unless that has been explicitly approved.

4:55 Business example: Manchester supplier workshop

Now a realistic business example. A project manager in Manchester runs a two hour supplier workshop in Teams. Afterwards she asks Copilot for decisions, actions with owners and open risks. The summary says the team agreed to extend the deadline, but she remembers it was only proposed, so she corrects it, then checks two owner names against the attendee list. She drafts the follow up in Outlook with Copilot and asks Excel to update the risk register from the notes. By her estimate, an hour of follow up became twenty minutes, and every correction happened before anything was sent. She then saved her three most useful prompts, the meeting recap structure, the follow up draft and the risk register update, in a OneNote page shared with her project team. Within a month, the whole team's meeting follow ups had the same clear structure, and the supplier commented that actions and owners had never been clearer.

6:02 Common mistakes

Let's name the common mistakes. Pasting work data into the consumer Copilot instead of your work account. Forwarding meeting summaries without checking decisions and owners. Transcribing meetings without telling people. And sending generic drafts as if they were finished, when a sentence or two of your own specifics would make them land. Avoid those, and Copilot becomes a trusted part of your day.

6:29 Watch me do it, part 1

Let me do the Manchester supplier workshop follow up. In the Teams meeting recap I ask Copilot for decisions, actions with owners and due dates, and open risks. The recap appears. The first decision says the team agreed to extend the deadline. I remember it was only proposed, pending the supplier's confirmation, so I correct it. Then I check the owners against the attendee list. One action is assigned to Ben, but nobody called Ben attended. The notes show it was Bea from procurement, so I fix it.

7:07 Watch me do it, part 2

Next, Outlook. I ask Copilot to draft a follow up to all attendees using the corrected recap, under one hundred and fifty words, with actions as a list. The draft is clear but generic in the opening, so I add one specific line thanking the supplier for the site visit. Then Excel. I open the risk register and ask Copilot to add any new risks from the meeting notes with owners and a rating. It adds two rows. I check both against my notes, adjust one rating, and then send the email myself. Twenty minutes, all checked.
