108,582 of the 1,000,000 top sites in our Tranco top-1M census run Microsoft 365 (10.9%). Microsoft's subscription suite of productivity apps and services, including Exchange Online email hosting. Detection is homepage-level HTML/header fingerprinting, so a site can run Microsoft 365 on other pages without it showing here.
