Get started with Microsoft 365 Copilot

Two-voice bite. HOST and GUEST. Objective: describe what Copilot is and write a prompt with the four parts.

HostWelcome to a LearningBites bite. Five minutes, one idea, done properly. Today: Microsoft 365 Copilot. I've got our guest here to keep me honest. First question — what actually is it?

GuestSimple version: it's an AI assistant that works inside the apps you already use. Word, Outlook, Teams, Excel, PowerPoint. You don't go to a separate website. It's right there in the app.

HostAnd where does it get its answers?

GuestTwo places, put together. One, a large language model — the part that can write and summarise. Two, your own work content: your emails, your chats, your files, your meetings. It reaches that through something called the Microsoft Graph.

HostSo it's reading my emails?

GuestOnly the ones you already have access to. It doesn't get to see anything you couldn't open yourself. Your permissions still apply.

HostGood. That's the bit people worry about. So if I'm sat in Word on a Monday morning, what do I actually do with it?

GuestThink in three verbs. Draft, summarise, ask. Draft — make something new, like a first version of a document. Summarise — take something long and shorten it. Ask — put a question to content you already have.

HostGive me a real one.

GuestYou missed a meeting. Open Teams, ask Copilot to summarise it. It uses the transcript and tells you what you missed. Or a long email thread in Outlook — ask it to summarise that thread for your manager. Same three verbs, different app.

HostSo the trick is pick the verb, then pick the app.

GuestPick the verb, then go to where the content lives. Meeting, Teams. Document, Word. Spreadsheet, Excel. Email, Outlook.

HostNow the part everyone gets wrong. The prompt. What makes a good one?

GuestFour parts. A goal — what you want it to produce. Context — why, or who it's for. A source — what it should use. And expectations — how long, what format, what tone.

HostCan you say that as one sentence?

Guest"Summarise this email thread for my manager in five plain-English bullet points, ending with next steps." Goal: summarise. Context: for my manager. Source: this thread. Expectations: five bullets, next steps. All four, one good answer.

HostAnd if the answer's not quite right?

GuestChange one part and ask again. Iterating is part of the method, not a failure. And always read it before you use it. Copilot can be wrong — Microsoft's own guidance says to review and verify. You stay responsible for what goes out.

HostSo the one thing to remember?

GuestA model plus your own data. Pick a verb — draft, summarise, ask. Write a prompt with a goal, context, source, expectations. Then check it.

HostThat's the bite. Next time: Copilot Studio — building your own agent. Thanks for listening.
