☕ SharePoint Tip #25 — Microsoft 365 Copilot: SharePoint as your AI brain

Posted on by

Good morning! Here is your 15-minute SharePoint tip for today.

Day 25 | Week 4 — Product Owner Mastery

Microsoft 365 Copilot and SharePoint

Microsoft 365 Copilot is the AI assistant built into the M365 suite — and SharePoint is its knowledge base. Understanding how Copilot uses SharePoint is one of the most strategically important topics for a Product Owner in 2025 and beyond.

How Copilot uses SharePoint

When a user asks Copilot "Summarise last quarter’s project reports" or "What is our policy on remote working?", Copilot searches the user’s accessible SharePoint content using Microsoft Graph and surfaces an answer with citations.

This means: the quality of your SharePoint directly determines the quality of Copilot answers.

  • Well-organised content with good metadata → accurate, relevant Copilot responses
  • Poorly named files in deep folder structures → Copilot struggles to find relevant content
  • Outdated documents → Copilot surfaces stale information confidently

Copilot respects permissions

Copilot only surfaces content the signed-in user has access to. If a file is in a restricted library, Copilot will not include it in responses — even if it would be relevant. This is a feature, not a limitation. But it means over-permissioned content becomes a Copilot risk — Copilot may surface confidential content to users who technically have access but shouldn’t realistically be reading it.

Preparing SharePoint for Copilot

Audit and clean up — remove or archive outdated content before enabling Copilot. Stale content = bad answers.

Review permissions — run an access review. Does everyone who has access to sensitive libraries really need it? Copilot amplifies over-permissioning.

Improve metadata and titles — files named "v3_FINAL_revised.docx" confuse Copilot. Rename with clear, descriptive titles.

Publish key policies as SharePoint pages — Copilot reads page content better than it reads buried Word documents. Publish your HR policies, IT procedures, and governance documents as SharePoint news/pages.

Try it today (5 minutes)

Go to your most important SharePoint library. Look at the last 10 files. Are the file names clear and descriptive? Are the titles filled in (not just the filename)? Could Copilot understand what each file contains from its name alone? Fix 3 filenames right now. This is Copilot readiness in practice.

As a Product Owner

Copilot readiness is a SharePoint quality initiative. Your governance work, metadata strategy, and permissions hygiene — everything we’ve covered in this 30-day series — directly prepares your organisation for AI. Position your SharePoint improvement programme as "Copilot readiness" to executives. It’s the language that unlocks budget.
