Microsoft turns on AI page creation in SharePoint by default in June
Message Center item MC1311968 confirms Copilot in SharePoint begins an opt-out preview rollout to all tenants in mid-June 2026. The feature is available only to users who already hold Microsoft 365 Copilot licenses. Once enabled, licensed users can generate and edit page content with AI assistance directly inside SharePoint. Admins can still disable the preview at tenant level before the rollout starts. No additional licensing is required beyond existing Copilot seats, and the preview carries the usual warning that behaviour may change before general availability.
Until now Copilot only touched files users already had permission to see. The new SharePoint integration changes that by letting AI draft and surface content across any site the user can reach, including legacy pages and libraries that were never reviewed for external links or broken inheritance. The practical result is that every permission gap and abandoned site becomes visible the moment someone asks Copilot to 'improve this page' or 'summarise recent news'. Small teams that postponed cleanup now face the same exposure without extra headcount to handle the fallout.
Analysis
Opt out at tenant level today, then pick the 20 busiest communication sites and force a quick ownership and sharing review before mid-June instead of gambling that nothing sensitive surfaces.
