Microsoft turns on AI content creation in SharePoint by default
Reviewed by Helen Jones
Starting mid-June 2026, Copilot in SharePoint moves from opt-in to opt-out preview. Licensed users gain automatic access to natural language prompts for creating sites, pages, lists, libraries, reports, and files. Admins control exposure through Set-SPOTenant with KnowledgeAgentScope parameters: AllSites, IncludeSelectedSites, ExcludeSelectedSites, or NoSites. The list of included or excluded sites cannot exceed 100 items. Preview applies only to Microsoft 365 Copilot license holders. Daily and weekly usage limits remain in place. Government clouds and 21Vianet tenants are excluded.
Before this change, Copilot features stayed dormant until an admin deliberately enabled them. Permission problems, abandoned sites, and overshared content stayed hidden because AI search never reached them. Now the default is exposure. Every site that is not explicitly blocked becomes part of the AI surface. Restricted Content Discovery still works as a backstop, but most tenants never turned it on. The gap between what users can now generate and what admins have actually cleaned just widened overnight.
Analysis
Treat this as an immediate exposure event, not a feature release. Set KnowledgeAgentScope to NoSites or a vetted IncludeSelectedSites list today, then audit the sites you leave enabled before any user starts prompting.
