Copilot pilot claims hours saved mostly in Teams and Outlook
Reviewed by Helen Jones
Consultancy 2toLead published a 12-week Microsoft 365 Copilot pilot at a 2,000-employee global nonprofit on 9 September 2026. In a selected cohort it recorded 1,115.6 hours saved, about $83,700 in estimated productivity value, and 13,994 Copilot-assisted actions. Usage was not even across apps. Teams sat at 78% and Outlook at 68%, while Excel was 19% and PowerPoint 9%. Average post-meeting recap time was reported as falling from about 30 minutes to 5 minutes. The firm says 92% of the participating group used Copilot and that licence cost recovered in about 4.5 months. The write-up is consultancy-authored, the dollar figure is estimated rather than audited cash, and it covers a chosen cohort rather than all 2,000 staff.
Adoption conversations have treated licence counts and a single active-user percentage as proof that Copilot is working. That hid a simple pattern: people click Copilot where meetings and mail already create context, then give up in Excel and PowerPoint when the same vague prompt produces weak slides or tables. This case study, even as an early community signal, splits those layers. Recap time is a checkable before-and-after number. Hours and dollars are still estimates. If your organisation is still reporting usage as success, you will over-claim Excel and PowerPoint value and under-invest in the Teams and Outlook habits that actually moved in this cohort.
Analysis
Treat this as a measurement pattern to test, not as proof that your licences will pay back in 4.5 months. Pick one recurring meeting recap or long email thread, time the manual version once, then time the Copilot version with a short review checklist, and keep Excel and PowerPoint off the scorecard until those numbers exist.
