Previous rate = 180-day period ending 10 May 2026. App adoption is measured by the presence of a last-activity date — cumulative signal across the window.
Chat (Work) now at 100%, with Outlook (95.7%), Teams (94.6%), Word (87.1%), PowerPoint (84.9%), Excel (80.6%), and M365 App (75.3%) all firmly embedded. This tier is stable and strong. Focus should be on prompt quality and depth of use, not awareness. Excel's +4.3pp growth is a standout positive signal.
Loop (+5.4pp to 61.3%), Copilot Chat Web (57.0%), and Edge (46.2%). Loop's growth is the most notable in this tier — approaching the 65% mark. A structured Loop pilot for 1–2 teams could push this above 70% in the next period. Web chat is growing steadily, likely reflecting external search and research use cases.
Copilot Agents (21.5%, +1.1pp) and OneNote (15.1%, flat) remain the largest adoption gaps. Agent adoption has barely moved across two reporting periods despite being flagged as the highest-value surface. The slow pace of growth here — just 1 additional user since the last snapshot — points to a lack of structured enablement rather than user resistance. A named pilot programme with defined use cases and owners is the required next step.
