One page. Tape it to the wall. Everything you need to get a good answer from Microsoft 365 Copilot — and to know when not to trust it. Most Copilot advice oversells. You tried it, got a mediocre answer, and stopped. This page is the opposite: the whole working system on a single sheet, no fluff, nothing held back. It's the page I keep next to my own desk while deploying Copilot across a 17,000-person engineering company. What's on it THE LOOP — how good work actually gets done: Ground → Draft → Check → Decide. THE PROMPT — the four parts every good prompt has: Goal · Context · Source · Format. THE RULE — five words that keep you out of trouble: AI prepares. You decide. THE 3 RISKS — what to watch for, every time: Hallucination · Mis-citation · Over-trust. That's the system. Print it, pin it, share it with your team. It works the same whether you've had your licence a week or a year. Who it's for Anyone with a Microsoft 365 Copilot licence who wants real results — PMs, finance, ops, HR, executive assistants, managers, consultants. Not a guide for admins deploying Copilot or execs evaluating it; this is for the people actually using it. Pay what you want — including nothing It's $0+. Take it for free, or pay what it's worth to you. Either way, please pass it around. When you want it app by app The page is the method. The Honest M365 Copilot Kit is the method applied: 14 reference cards (5 foundations plus 9 app cards for Outlook, Word, Excel, PowerPoint, Copilot Chat, Notebooks, Cowork, Teams, and Researcher & Analyst), each with the 3 prompts that work, the 3 mistakes to avoid, and what to not use Copilot for at all. With a 30-minute user guide and a two-week practice plan. $39. Rolling Copilot out to other people rather than using it yourself? That is a different problem, and a different kit: the 90-day M365 Copilot Deployment Kit is the week-by-week roadmap with named owners, the governance checklist, and the ROI conversation template. $97.
