What it does

Why it’s useful

For a mainstream team, the best AI tool is often the one inside the software they already use. The learning focus is not novel prompting; it is how to ask Copilot for useful work while respecting file permissions, meeting context, and review boundaries.

How to learn it

Teach three Office-native workflows: summarize a Teams thread, draft a client email from approved notes, and turn a spreadsheet into a decision-ready slide. Keep each exercise inside Microsoft 365 to avoid copy-paste risk.

Core topics to study

Office-native contextUsing files, meetings, and email threads where they already live.

Permission inheritanceUnderstanding what Copilot can and cannot see.

Document reviewTreating generated drafts as first drafts, not approved records.

Meeting follow-throughConverting calls into action lists without losing accountability.
