SharePoint vs Microsoft Teams: When to Use Which

The most-asked question in Microsoft 365 — answered with a clear decision framework and the surprising truth about how these tools relate.

SharePoint & Teams May 23, 2026 6 min read

"Should we put this in SharePoint or Teams?" is the question we hear on almost every Microsoft 365 engagement. It causes genuine confusion, creates duplicate content, and often results in neither tool being used well. The answer requires understanding what these tools actually are — and the surprising relationship between them.

The Surprising Truth: Teams IS SharePoint

Every Microsoft Teams team automatically creates a SharePoint site behind the scenes. Every Teams channel gets its own document library folder within that site. When you upload a file in a Teams channel, it is stored in SharePoint — you're just accessing it through the Teams interface.

This means the question isn't really "SharePoint or Teams?" — it's "which interface is right for this audience and this use case?" Teams and SharePoint are deeply integrated layers of the same platform, not competing alternatives.

Files shared in Microsoft Teams are stored in SharePoint document libraries. Version history, metadata, permissions, and retention policies all apply automatically — Teams simply gives you a different way to access and collaborate on that content.

What SharePoint Is Best For

SharePoint is the publishing and governance layer of Microsoft 365. It excels at:

Company intranets — branded communication sites with news, announcements, policies, and an org-wide search experience
Formal document management — structured libraries with metadata, content types, retention labels, and approval workflows
External-facing portals — project extranets and client portals where specific external users need controlled access
Broad publishing — content intended for a large, varied audience beyond a single team (HR policies, IT procedures, company news)
Compliance archival — content subject to records management, legal hold, or regulatory retention requirements

SharePoint pages are designed to be navigated and read by many people, not just edited by a small team. Communication sites — as opposed to team sites — are the right format when your goal is broadcasting information, not collaborative workspaces.

What Microsoft Teams Is Best For

Teams is the real-time collaboration and communication layer. It excels at:

Day-to-day team collaboration — ongoing conversation, quick questions, and contextual file sharing within a working group
Meetings and calls — scheduled and ad-hoc video meetings, meeting recordings, transcripts, and meeting notes
Project workspaces — a self-contained environment for a project team with channels, files, a Planner board, and shared notebooks
Cross-functional task coordination — looping in people from multiple departments with @mentions and shared task lists
Chat-based workflows — quick, conversational work that doesn't need to live in a structured document library

Teams is designed around conversation first. The interface prioritises activity, notifications, and participation — it's not well-suited for read-heavy content consumption by a broad audience.

Side-by-Side Comparison

Scenario	Best tool	Why
Company-wide HR policy library	SharePoint	Broad audience, formal structure, version control needed
Marketing team's daily collaboration	Teams	Ongoing conversation, quick file sharing, meetings
Client-facing project extranet	SharePoint	Controlled external access, no need for external chat
Cross-department product launch	Teams	Real-time coordination across multiple stakeholders
Company intranet homepage	SharePoint	News publishing, org directory, search for all staff
Weekly team stand-up & follow-ups	Teams	Meetings, chat, action items in one place
Contract repository with approval workflow	SharePoint + Power Automate	Metadata, retention, structured approval routing
Onboarding a new employee	Both	Teams for daily intro; SharePoint for policies and handbook

The Three-Question Decision Framework

Ask these three questions before creating a new team or site:

1. Who is the audience? If it's a small, known working group who need to actively collaborate → Teams. If it's a broad organisational audience consuming information → SharePoint.

2. What's the interaction model? If people will be chatting, meeting, and editing together in real time → Teams. If people are mainly reading, searching, and referencing content → SharePoint.

3. What's the lifecycle? If the content has a defined end date (project team, campaign workspace) → Teams. If the content is permanent and organisational (policies, intranet, records) → SharePoint.

The Hybrid Approach: Using Both Together

Many of the best Microsoft 365 implementations use Teams and SharePoint in deliberate combination. A project team lives in Teams for daily work — then at project close, key deliverables and learnings are published to a SharePoint communication site visible to the wider organisation. The Teams site can even embed a SharePoint page as a tab, giving team members a view of the broader context without leaving their workspace.

Viva Connections takes this further — it brings the SharePoint intranet directly into the Teams interface as a tab, meaning employees can access company news, policies, and tools from Teams without ever needing to navigate directly to SharePoint.

What to Do Right Now

If your organisation doesn't have clear guidance on when to create a Teams team vs a SharePoint site, you're likely accumulating both. Here's a quick action plan:

Audit your existing Teams and SharePoint sites — identify overlap and consolidation opportunities.
Define a provisioning policy: what triggers a new Teams team, what triggers a new SharePoint site.
Set naming conventions for both, enforced through a request process or automated via Microsoft Forms + Power Automate.
Publish the guidance on your intranet (naturally, in SharePoint) so all staff know where to look.
