Copilot in SharePoint (formerly called AI in SharePoint) is officially moving to an opt-out preview starting mid-June 2026.
The experience will automatically appear for users with a Microsoft 365 Copilot license unless admins proactively disable it at the tenant or site level. What makes this announcement important is that Microsoft is finally bringing together years of investments across:
- Project Cortex (Precessor)
- SharePoint Syntex
- Microsoft Syntex
- SharePoint Premium
- AI in SharePoint
…into a much more operational AI experience inside SharePoint itself.
Copilot in SharePoint
Users will see a floating Copilot button across SharePoint sites, pages, document libraries, and lists.
The experience is fully permission-trimmed; Copilot only accesses content users are already authorized to view or edit within SharePoint. The capabilities go far beyond simple AI chat:
- Build and edit pages, sites, and HTML reports using prompts
- Organize libraries and populate metadata automatically
- Create and update lists through natural language instructions
- Find and remediate missing or incomplete content
- Encode organization-specific processes as reusable “skills” so Copilot follows your team’s operational playbook
The existing Site Agents experience will also transition into Copilot in SharePoint for licensed users automatically. Pay-as-you-go billing remains applicable only for custom SharePoint agents.
Another notable detail: Microsoft confirmed the rollout will initially use OpenAI’s GPT-5.4 Reasoning model, with no customer-controlled model selection available at this stage.
SharePoint is steadily evolving from a content repository into an AI-powered business process and knowledge platform, and Copilot in SharePoint feels like one of the biggest steps in that transition so far.
