Summarize Teams conversations on leave return with Copilot at Peaksys

Use described publicly by Les Echos — Sandrine Mercier (Peaksys / Cdiscount) (16 June 2025), summarised by the desk. Not tested by iadujour.

The result to aim for

Sandrine Mercier, head of engineering at Peaksys (Cdiscount's tech subsidiary, about twenty developers), asks Copilot, in Teams, for a summary of the key points of the missed conversations: within minutes, without rereading all the messages.

What was done

Les Echos (Chloé Marriault, June 16, 2025). Peaksys: more than 600 employees. Use since 2024. Another gesture, out of title: recording Teams (with agreement) then synthesis for a report and assignment of Tasks. Distinct from the catbot product sheets already Cdiscount to the corpus. No volume of years summarized or error rate is published.

Before you start

Tool cited by the source: Microsoft 365 Copilot (Teams); other tools cited: Microsoft 365 Copilot. Fill in the bracketed items: [coller 12 lignes], [congés]. Strip confidential data that is not needed and check your tool’s access terms. Features and plans can change.

The method, in three steps.

  1. Gather the context

    Spot the bracketed items in the prompt ([coller 12 lignes], [congés]) and prepare what they ask for.

  2. Adapt the prompt

    Copy the prompt below, replace the bracketed items, then paste it into Microsoft 365 Copilot.

  3. Reread before using

    Reread the result, correct it if needed and keep the final decision. Caveats are detailed below.

Your starting point.

Replace the bracketed items, then adapt the proposal to your situation. This prompt is written by the iadujour desk It is not a quotation from the source.

The prompt to customise
Wire Teams (made, without name): [coller 12 lignes]. Period: [congés].

Proposes 8 key points only after the thread. If a deadline is missing, say so. Don't make up any commitment.

What deserves your attention

A generated summary is not the decision. Cross-check key points on the Teams feed before hiring the team, and do not paste customer data into a mainstream account.
Origin of the case. Use described publicly by Les Echos — Sandrine Mercier (Peaksys / Cdiscount) (16 June 2025).
Proof level: Testimony published by an identified source. Source checked on 10 November 2026. Use described by the source, not tested by the desk. Original summary written by iadujour.fr: figures and claims are the source’s; the prompt is a desk proposal, not a quotation.
