SharePoint is Microsoft’s platform for document management, intranet communication, and team collaboration — included in all Microsoft 365 business and enterprise plans. It is the underlying system where files shared in Microsoft Teams are stored, where organization-wide intranet content lives, and where document libraries and version history for business-critical files are managed.
For many organizations, SharePoint operates invisibly — Teams users share files without realizing those files are in SharePoint behind the scenes. But SharePoint’s value goes well beyond being Teams’ file storage layer. Organizations that understand and use it deliberately use it to replace shared drives, build internal communication sites, standardize document templates, and automate approval workflows.
Overview
SharePoint serves three primary functions in most Microsoft 365 organizations: document management (organizing, versioning, and securing business files), intranet communication (publishing company news, policies, and resources to all employees), and team collaboration (shared workspaces where project teams co-author documents and organize their files). Each function addresses a specific organizational need; many organizations use SharePoint for all three simultaneously.
- Document management: organized document libraries with version history, permissions, and metadata
- Intranet: company news, policies, organizational information published to all employees
- Team sites: collaboration workspaces organized around teams or projects
- Business process: approval workflows and forms using Power Automate and Power Apps
- Integration: deeply connected to Teams, OneDrive, Microsoft Search, and Microsoft 365 Copilot
The 5 Why’s
- Why does SharePoint specifically replace the shared drive or file server for most Microsoft 365 organizations? Shared drives and file servers store files locally with limited version history, no co-authoring, and access management that requires IT involvement for every change. SharePoint document libraries provide version history for every document (restore any prior version), real-time co-authoring (multiple users edit simultaneously), metadata and tagging for better findability, and permission management that team owners can handle without IT tickets. For cloud-forward organizations, SharePoint is the modern replacement for the file server.
- Why does Teams using SharePoint for file storage specifically matter for governance? When a file is shared in a Teams channel, it is stored in the SharePoint document library for that team’s site. Permissions set on the SharePoint site affect what Teams members can access. Compliance policies applied in SharePoint govern files shared through Teams. Understanding this connection is essential for organizations managing compliance, data retention, and document governance — the SharePoint layer is where those controls operate.
- Why is the SharePoint intranet specifically valuable for organizations with distributed workforces? A SharePoint intranet centralizes the organizational information that employees need: company news, HR policies, benefits information, organizational charts, and department resources. For employees who do not come to a central office, the intranet provides the organizational context and shared information that previously required physical presence or email announcements. A well-maintained SharePoint intranet reduces “where do I find X?” questions and keeps distributed teams aligned.
- Why does version history in SharePoint specifically eliminate the “final_v3_REAL_final” file naming problem? When documents are managed in SharePoint, SharePoint maintains version history automatically — every save creates a version record that can be reviewed or restored. Users do not need to save multiple copies with descriptive names to preserve prior states; they can restore any previous version from the version history panel. For business-critical documents, this capability eliminates the risk of losing prior states due to file overwriting.
- Why is metadata and search specifically more powerful in SharePoint than in a traditional file system? Traditional file systems find files by filename and folder location. SharePoint documents can be tagged with metadata — document type, project, department, status, author — that enables search filtering beyond filename. Microsoft Search in SharePoint and across Microsoft 365 indexes SharePoint content and returns results based on content relevance, not just filename matching. For organizations with large document repositories, findability through metadata and search produces significant time savings.
SharePoint Use Cases in Practice
Document Management and Libraries
SharePoint document libraries are organized file repositories with:
- Version history: every document has a complete edit history; restore any prior version
- Check-out: optionally lock a document for exclusive editing to prevent conflicting changes
- Metadata columns: tag documents with custom fields for better organization and findability
- Views: filter and display document libraries by metadata criteria (e.g., show only documents from Q3, or only documents in “Review” status)
- Co-authoring: multiple users edit the same Word, Excel, or PowerPoint document simultaneously
Intranet Communication Sites
SharePoint communication sites are designed for broad organizational publishing:
- Company news and announcements
- Employee handbook and policy documentation
- Benefits and HR information
- Organizational charts and directory
- Department resource pages
- Event calendars
Communication sites are typically owned and maintained by HR, marketing, or communications teams and are read by all employees.
Team Collaboration Sites
SharePoint team sites are workspaces for specific teams or projects:
- Organized document libraries for team files
- Shared calendar
- Links to frequently accessed resources
- Discussion boards (though Teams channels have largely replaced these)
- Team-specific pages for project documentation
Every Microsoft Teams team has a corresponding SharePoint team site where its files are stored.
Business Process Automation
SharePoint integrates with Power Automate and Power Apps to automate business processes:
- Approval workflows: document approval routing through Power Automate — submitted documents route to designated approvers with notifications and audit trail
- Forms: Power Apps forms that submit data to SharePoint lists
- Automated notifications: alerts triggered by document changes, new list items, or status field updates
Common SharePoint Challenges and How to Address Them
- Governance: without naming conventions and ownership policies, SharePoint sites proliferate and become difficult to manage. Address with a site creation policy and an annual site review process.
- Adoption: employees revert to email attachments and local files if SharePoint feels harder to use than familiar alternatives. Address with training and by ensuring SharePoint is the default save location in Office applications.
- Permissions complexity: overly granular permissions that differ at folder and file level create management complexity. Address with site-level permissions and documented permission tiers.
Final Takeaway
SharePoint is used for document management, intranet communication, and team collaboration — and it is the file storage foundation beneath Microsoft Teams. Organizations that use SharePoint deliberately, with clear governance and user adoption, replace shared drives, reduce email attachments, and build the organizational knowledge and communication infrastructure that distributed workforces need. Those that let it grow without governance accumulate the SharePoint equivalent of a cluttered filing cabinet.
