Pick a recurring task and write it in RTCF format (Role, Task, Context, Format). Check your licence tier and remember: no company data in a consumer Copilot.
Turn rough notes into a structured document with "Draft with Copilot", summarize a long document, then reference a file with "/". Apply the 70/30 rule: you own the decisive 30%.
Convert a range into a table (Ctrl+T), query your data in natural language, generate a formula (and "explain this formula"), then a chart describing the message. Test every formula on a known case.
Create a presentation from a Word document (validate the outline before the form), then write an Outlook email in the right tone — and re-read before sending.
On a transcribed meeting (announced to participants), get the summary and actions; test the live catch-up; capture a good answer in Copilot Pages.
In Copilot Studio, create a simple agent (instructions + clean knowledge), test it before sharing, and note the safeguards: permissions, confirmation, supervision.
