If you’ve been using SharePoint for a few years – managing document libraries, building intranets, wrestling with permissions – you’ve probably noticed that it doesn’t feel quite the same as it did even twelve months ago. That’s not your imagination. Microsoft has been quietly (and sometimes not so quietly) transforming SharePoint into something it was never originally designed to be: an AI-native knowledge platform. And the pace of change in 2025–2026 has been faster than anything we’ve seen since SharePoint first moved to the cloud.
Whether you’re an IT admin, a developer building SPFx web parts, or a business owner trying to figure out how Microsoft’s roadmap affects your team, this article walks you through the most important updates, the changes you can’t afford to ignore, and an honest look at where SharePoint is heading next.
The Headline Story: SharePoint Is Now an AI Platform First
Let’s get the big picture out of the way before diving into the specifics.
For most of its life, SharePoint was a place to store files and build portals. Useful, but rarely exciting. In 2026, that framing has fundamentally shifted. Microsoft has repositioned SharePoint as the primary content backbone for Copilot and AI agents across the entire Microsoft 365 suite. Every major update this year connects back to that goal – better metadata, stronger governance, smarter search, and AI agents that can reason across your content.
The practical implication is this: the better your SharePoint is organised, the more value you’ll get from every AI feature Microsoft ships. That’s a real change in stakes. Messy SharePoint used to mean people couldn’t find files. Messy SharePoint now means your AI assistant gives you bad answers.
Key Updates You Need to Know About
Copilot in SharePoint (Formerly “AI in SharePoint”)
This is probably the most significant feature to land in 2026. What started as the “SharePoint Knowledge Agent” in September 2025 has been rebranded and expanded into Copilot in SharePoint, now rolling out in preview from mid-June 2026.
The core idea is genuinely impressive: instead of navigating through document libraries, users can simply describe what they want to build or find in plain language. Need a project tracker? Describe it. Want to create a new team site with a specific structure? Ask for it. The agent builds it.
Beyond creation, Copilot in SharePoint automatically extracts and applies metadata to new uploads, adapts libraries as content changes, and helps keep information structured for downstream AI experiences across Microsoft 365. Every SharePoint site now gets a pre-configured agent – you ask it “What’s our policy on X?” and it reasons across all documents in that site to give a cited answer.
This is no longer a future feature. It’s here.
SharePoint Agents in Microsoft Teams
SharePoint agents don’t just live in SharePoint anymore. Since January 2026, users can discover and add SharePoint agents directly inside Microsoft Teams – through the Teams Store or via the Add Agents option in any chat. If your team lives in Teams, they can now access their SharePoint site knowledge without ever switching tabs.
This also works the other way: agents built with Copilot Studio can connect specifically to SharePoint lists and libraries to automate workflows like contract approvals, project tracking, or vendor communications. The boundary between SharePoint and Teams is effectively dissolving.
SharePoint List Agent (Copilot-Powered)
One of the smaller but genuinely useful updates that rolled out between December 2025 and February 2026 is the SharePoint List Agent. It lets users create SharePoint lists through natural language conversations – no more clicking through columns and data types. Tell Copilot what you want to track, and it builds the structure for you.
Lists have always been one of SharePoint’s most underused features, partly because setting them up properly requires a bit of technical thinking. This update removes that barrier for everyday users, which should dramatically increase adoption for structured data capture across organisations.
The New Permissions Report – Finally
This one will make SharePoint admins very happy. A new Permissions Report has been added to the SharePoint Admin Center under Data Access Governance. It shows which sites a user can access, including both direct and group-based permissions, all in one place.
Permissions sprawl has historically been one of the nastiest governance problems in SharePoint environments – you couldn’t easily see what access a given user had without running custom scripts or using third-party tools. This report changes that, and it requires no configuration to use.
Content Security Policy Enforcement for SPFx
From March 1, 2026, Microsoft began enforcing Content Security Policy (CSP) on SharePoint Online for custom SPFx solutions. This means scripts loaded from non-trusted or unapproved sources will now be blocked.
If you’re a developer or you manage custom web parts, this requires attention. Any SPFx solution that loads scripts from external CDNs, uses inline scripts, or pulls resources from unapproved locations needs to be reviewed and updated. Microsoft did provide a 90-day delay option via PowerShell, but that window is either closing or already closed depending on when your organisation opted in.
The intent is solid – this significantly hardens SharePoint against modern security threats – but it’s one of those updates that catches teams off guard if they’re not actively monitoring the roadmap.
Classic SharePoint Publishing Is Being Locked Down
Between September 2025 and March 2026, Microsoft has been disabling custom scripting by default on all classic publishing site collections. New customisations, master pages, or page layouts are no longer possible without temporarily re-enabling scripting, and that option expires permanently on March 15, 2026.
To be clear: existing classic publishing sites are not being deleted. But they’re effectively in maintenance mode now. They’ll keep running, but you can’t grow them, customise them meaningfully, or expect long-term investment from Microsoft.
If your organisation is still running classic SharePoint publishing sites, this is the moment to start planning your migration to modern. It’s not optional anymore – it’s a question of when, not whether.
End of Support for SharePoint Server 2016 and 2019
This one deserves its own paragraph. Support for SharePoint Server 2016 and 2019 ends on July 14, 2026. After that date, Microsoft will no longer provide security updates or paid support.
Similarly, InfoPath Forms Services will be fully retired from SharePoint Online after July 14, 2026. If you’re still using InfoPath, you need to migrate to Power Apps, Power Automate, or Microsoft Forms before that deadline – this retirement applies to all environments including government clouds.
If you’re still on-premises and haven’t started planning your migration to SharePoint Online, the clock is ticking loudly now.
OCR for Scanned PDFs in OneDrive and SharePoint Mobile
A small but welcome update: OneDrive and SharePoint mobile apps now include built-in OCR for scanned PDFs, making them editable and searchable. This is particularly valuable for legal, finance, and operations teams who deal with a lot of scanned documents. No admin setup required – it works by default.
The broader significance here is that it reduces what Microsoft calls “dark data” – information that exists in your SharePoint environment but can’t be searched or used by AI tools because it’s locked inside image-based files.
Catalog Management for Admins
SharePoint Advanced Management now includes Catalog Management, a centralised, intelligent site clustering tool that automatically groups sites based on metadata and admin-defined attributes. It enables scalable governance at scale – lifecycle policies, access reviews, permissions auditing, and storage optimisation – all from one dashboard.
For organisations with hundreds or thousands of SharePoint sites, this is a meaningful step toward making governance manageable without needing a dedicated team of PowerShell experts.
A New FAQ Web Part
In February 2026, Microsoft quietly shipped a new native FAQ web part for SharePoint pages. This might seem minor compared to the AI updates, but it’s genuinely useful for knowledge bases, HR portals, and intranet pages where accordion-style Q&A has traditionally required custom development or third-party tools.
What’s Happening with SPFx in 2026
For developers building on the SharePoint Framework, the March 2026 SPFx roadmap update from Microsoft confirmed that SPFx remains a first-class extensibility platform – but the direction is unmistakably AI-first.
Microsoft’s focus for SPFx in 2026 is on AI-powered portals, deeper integration with Microsoft Graph and Copilot, and improved developer tooling for building agent-backed experiences. The SharePoint 2026 Hackathon in March drew strong community participation, and Microsoft signalled that future SPFx updates will continue expanding capabilities specifically for AI scenarios.
One breaking change developers need to be aware of: Domain-Isolated Web Parts have been fully removed as of April 2026 for all existing tenants. If you have web parts using this architecture, migration is no longer optional.
The Future of SharePoint: What’s Coming Next
Reading through everything Microsoft has shipped and signalled, a clear picture emerges of where SharePoint is heading over the next two to three years.
From Document Storage to Knowledge Infrastructure. SharePoint’s identity is shifting from “where we keep files” to “the trusted content backbone that powers AI across Microsoft 365.” Every investment Microsoft is making – Copilot integration, metadata automation, governance tooling – is designed to make SharePoint a reliable, structured source of truth that AI agents can reason across accurately.
Agentic Automation as the Default. The introduction of the SharePoint Admin Agent, which lets admins manage their tenant using natural language, is a preview of where all SharePoint administration is heading. Within a few years, routine tasks like identifying inactive sites, reviewing permissions, and enforcing governance policies will be largely automated through AI agents.
SharePoint Embedded for Custom Apps. For developers building enterprise applications, SharePoint Embedded is opening up SharePoint’s document management infrastructure – security, compliance, version control, real-time collaboration – as a backend for custom apps hosted outside Microsoft 365 with entirely custom UIs. Upcoming milestones include integration with Azure AI Foundry and new Power Automate connectors for document processing workflows.
Modern-Only, No Exceptions. Microsoft has made it abundantly clear that the future is modern SharePoint. The lockdown of classic publishing, the retirement of InfoPath, the end of support for Server 2016 and 2019 – these aren’t isolated decisions. They’re part of a deliberate strategy to concentrate investment in the cloud-based, modern experience.
Content Quality Becomes a Competitive Advantage. Perhaps the most underappreciated implication of the AI era for SharePoint is this: organisations with well-structured, well-governed, metadata-rich SharePoint environments will get dramatically better results from Copilot than organisations with sprawling, unorganised content. The quality of your SharePoint is now the quality of your AI assistant.
What Should You Do Right Now?
If you’re responsible for SharePoint in your organisation, here’s a practical short list:
If you’re on SharePoint Server 2016 or 2019: Start your migration planning immediately. Support ends July 14, 2026, and migrations take time. Don’t wait until you’re patching security vulnerabilities without vendor support.
If you’re using InfoPath Forms Services: Identify every form and begin migrating to Power Apps or Power Automate. The deadline is the same – July 14, 2026.
If you have custom SPFx solutions: Audit them for CSP compliance. Any solution loading scripts from unapproved sources needs to be updated now that enforcement is live.
If you’re still running classic publishing sites: Use Microsoft’s Modernisation Scanner to understand what you have, prioritise business-critical migrations, and build a realistic timeline. The PowerShell delay option is not a long-term strategy.
If you’re planning for Copilot adoption: Start with your content. Audit your SharePoint for well-organised, metadata-tagged, current content – that’s where you’ll run your AI pilots. Sites with poor structure will produce poor AI results.
Final Thoughts
SharePoint has always been one of those products that people love to complain about – and sometimes for good reason. But what’s happening in 2026 represents the most meaningful evolution the platform has ever undergone. The transition from file storage to AI-powered knowledge infrastructure isn’t just a marketing rebrand. The features being shipped – agents, Copilot integration, automated governance, OCR, natural language administration – reflect real engineering investment in a genuinely new direction.
The organisations that will get the most value from these changes are the ones that treat SharePoint governance as a strategic priority, not a maintenance task. That’s the real message underneath all the roadmap updates.
The platform is changing. The question is whether your approach to it will change along with it.
