SharePoint Best Practices
Governance, Security, AI Integration & Enterprise Content Management - Expert guidance from Microsoft's original Project Tahoe beta team
From Project Tahoe to SharePoint Online
EPC Group's founder, Errin O'Connor, was part of Microsoft's original SharePoint beta team known as "Project Tahoe" in 2001. This early involvement in the development of what would become one of the world's most widely adopted collaboration platforms provides EPC Group with unparalleled insight into SharePoint's evolution and best practices.
From the original SharePoint Team Services 2001 release through SharePoint 2003, 2007, 2010, 2013, 2016, 2019, SharePoint Server Subscription Edition, and now SharePoint Online in Microsoft 365, we've guided enterprises through every major version and architectural shift.
"Having been there from the beginning with Project Tahoe, I've seen SharePoint evolve from a simple document management tool to the backbone of enterprise collaboration and AI-powered content management. The fundamentals of good governance remain constant, but the capabilities have transformed dramatically."

SharePoint Best Practices FAQ
Common questions about SharePoint governance, security, and implementation
What is a SharePoint Governance Committee and why do we need one?
A SharePoint Governance Committee is a cross-functional team responsible for defining policies, standards, and procedures for SharePoint usage across your organization. It typically includes IT, legal, compliance, and business stakeholders. The committee ensures consistent site provisioning, security controls, content lifecycle management, and user adoption strategies. Without governance, SharePoint deployments often result in sprawl, security gaps, and poor user experience.
How do we implement a proper SharePoint security model?
A proper SharePoint security model follows the principle of least privilege using SharePoint groups (Owners, Members, Visitors) and Microsoft 365 Groups. Best practices include: never breaking permission inheritance unless absolutely necessary, using security groups instead of individual permissions, implementing sensitivity labels through Microsoft Purview, enabling conditional access policies, and conducting quarterly permission audits. External sharing should be restricted and governed with link expiration policies.
What are SharePoint Power Users and how do we develop them?
SharePoint Power Users are business users with advanced knowledge who serve as first-line support and champions within their departments. They understand site creation, list/library configuration, Power Automate workflows, and governance policies. Develop Power Users through structured training programs, certification paths, and regular community sessions. They reduce IT burden, accelerate adoption, and ensure business-driven configuration aligned with organizational needs.
How does AI integrate with SharePoint in 2025-2026?
AI integration with SharePoint has become essential through Microsoft Copilot, Microsoft Syntex, and Purview. Copilot enables natural language queries across SharePoint content, automatic document summarization, and intelligent search. Syntex provides automatic content classification, metadata extraction, and retention label application. Organizations need AI governance policies defining acceptable use, data boundaries, and compliance requirements. The integration of AI is moving from optional to mandatory for enterprise content management.
What are SharePoint Records Management best practices?
Modern SharePoint Records Management centers on Microsoft Purview retention labels rather than legacy Records Centers. Best practices include: defining retention schedules based on regulatory requirements (GDPR, HIPAA, SEC), using event-based triggers for disposition, enabling automatic classification with Syntex, implementing disposition reviews for sensitive records, and maintaining audit trails. The trend is moving from site-specific records management to unified, platform-wide governance across SharePoint, Teams, and Exchange.
How do we implement SharePoint ECM (Enterprise Content Management)?
Effective SharePoint ECM requires: defining content types and site columns at the root site level (not subsites), using metadata instead of folders for content organization, implementing document lifecycle policies, enabling version history with appropriate limits, configuring content approval workflows, and integrating with Microsoft Purview for compliance. Avoid renaming native fields like Title, and use remote provisioning for consistent Information Architecture across sites.
What are SharePoint intranet best practices for 2025-2026?
Modern SharePoint intranets should leverage: SharePoint home sites for organization-wide landing pages, Viva Connections for personalized employee experiences, news posts with audience targeting, mega menus for intuitive navigation, multilingual support for global organizations, and mobile-first responsive design. Content should be governed with publishing approvals, and analytics should track engagement. Integration with Teams, Viva Engage, and Stream creates a unified digital workplace.
How do we ensure SharePoint collaboration best practices?
SharePoint collaboration best practices include: using Microsoft 365 Groups for team sites, enabling co-authoring with AutoSave, implementing @mentions and comments, integrating with Teams for real-time communication, using Planner for task management, configuring alerts and flows for notifications, and enabling guest access with appropriate controls. Train users on version history, check-in/check-out when needed, and document library best practices to prevent file conflicts.

1. Enterprise Content Management (ECM)
Poor content management creates findability failures and compliance gaps. Follow these ECM fundamentals:
- Content types — Define reusable content types in the content type hub. Apply them site-wide so metadata stays consistent.
- Managed metadata — Use the Term Store for taxonomy terms. Avoid free-text columns for values that need to be filtered or reported.
- Document lifecycle — Set creation, review, and archive stages. Use retention labels to automate disposition.
- Retention policies — Apply Microsoft Purview retention policies at the site or library level. Do not rely on users to delete files.
- Version control — Enable major and minor versioning. Set a maximum version count (50 is a reasonable default) to manage storage.
2. Collaboration Best Practices
SharePoint collaboration works best when it is structured. Use Microsoft 365 Groups as the foundation:
- Microsoft 365 Groups — Every SharePoint team site should have an M365 Group. This links the site to a Teams channel, Planner board, and shared mailbox automatically.
- Co-authoring — Store Office files in SharePoint or OneDrive, not local drives. Co-authoring requires files to be in the cloud.
- @mentions — Use @mentions in comments and news posts to notify colleagues without leaving SharePoint.
- Teams integration — Surface SharePoint document libraries as Teams tabs. Keep files in SharePoint; Teams is the conversation layer.
- Planner — Attach a Planner board to each project team site. This keeps tasks and documents in the same M365 Group context.
- Guest access — Govern external sharing with sensitivity labels and expiration policies. Audit guest accounts quarterly.
3. Governance Best Practices
Governance is what keeps SharePoint usable at scale. Without it, sprawl and orphaned sites accumulate fast.
- Site provisioning policy — Require business justification before creating a new site. Use a Power Automate approval flow, not an open self-service portal.
- Naming conventions — Define a site URL and display name standard before go-live. Retroactively renaming sites breaks links and user bookmarks.
- Ownership requirements — Every site must have at least two active owners. Orphaned sites (no active owner) become security and compliance risks.
- Access reviews — Use Microsoft Entra ID access reviews to audit group memberships quarterly. Remove stale guest accounts automatically.
- Storage quotas — Set per-site storage quotas in the SharePoint admin center. Alert site owners at 80% capacity.
4. Information Architecture — Hub-Spoke Model
Hub-spoke is the recommended information architecture for SharePoint Online in 2026. EPC Group uses one hub per business unit with five to fifteen spoke sites.
- Hub sites — Aggregate search results, navigation, and news from all associated spoke sites
- Mega-menu navigation — Replace cascading left-nav menus with a flat mega menu on the hub. Users find content in two clicks.
- Sensitivity-label sharing controls — Set sharing policies at the hub level. Spokes inherit those controls automatically.
- Flat folder structure — Eliminate deep folder hierarchies. Use metadata filters and views instead of subfolders five levels deep.
Client results after migrating to hub-spoke flat IA:
- 60% faster content discovery
- 40% fewer helpdesk tickets related to "I can't find the file"
- 100% sensitivity-label coverage in 90 days
5. Intranet Design Best Practices
Modern SharePoint intranets use communication sites, not team sites. Design for the mobile reader first.
- Home site — Designate one SharePoint site as the organizational home site. This site surfaces in Viva Connections.
- Viva Connections — Deploy Viva Connections to bring the SharePoint intranet into Microsoft Teams. Employees access it without leaving Teams.
- News posts with audience targeting — Target news to specific departments, locations, or roles. Avoid broadcasting all news to all users.
- Mega menus — Use a flat, two-level mega menu on the home site. Navigation deeper than two levels increases time-to-content.
- Page templates — Create two or three approved page templates. This enforces brand consistency without requiring designers for every new page.
6. AI Integration Best Practices
Microsoft 365 Copilot uses SharePoint as a grounding source. Poorly governed SharePoint produces poor Copilot results.
- Sensitivity labels before Copilot — Every SharePoint site and document library must have a sensitivity label before Copilot goes live. Unlabeled content can surface to unauthorized users through Copilot responses.
- Restrict oversharing — Audit "Everyone except external users" permissions. Remove this group from sensitive sites before enabling Copilot.
- SharePoint search configuration — Copilot uses the SharePoint semantic index. Exclude irrelevant or outdated content from indexing using site exclusion policies.
- Agents and Copilot Studio — Build scoped agents in Copilot Studio that query specific SharePoint libraries. This limits Copilot to authorized content for each business function.
SharePoint Migration Best Practices
Most SharePoint environments have legacy content that needs cleanup before migration. EPC Group uses two primary migration tools:
- ShareGate — Best for permission preservation and granular reporting. Ideal for migrations under 10 TB.
- AvePoint Migrator — Best for large enterprise migrations with compliance chain-of-custody reporting.
Pre-migration best practices:
- Delete or archive content not accessed in 18+ months
- Flatten folder hierarchies before migrating — do not replicate old folder trees
- Validate permissions at source; do not assume they are correct
- Run a pilot migration on a non-critical library first
Frequently Asked Questions
What is the most important SharePoint best practice in 2026?
Governance before sprawl. The single biggest SharePoint failure pattern is site sprawl — hundreds of sites with no owners, inconsistent permissions, and no retention policies.
Establish a governance framework before you allow self-service site creation. Define who can create sites, what naming conventions apply, and who is accountable for each site.
Should we use folders or metadata in SharePoint?
Use metadata instead of deep folder hierarchies. Folders are familiar but they hide content from search and make permissions messy. Metadata columns let users filter and sort without navigating into nested folders. Use one or two folder levels for basic organization, then rely on views and filters for everything else.
How do we prevent SharePoint sprawl?
Three controls work together. First, require business justification for new site requests — use a Power Automate approval flow. Second, enforce a minimum of two active site owners. Third, run quarterly access reviews that flag sites with no active owner and no activity in 90 days. Delete or archive those sites after confirmation.
What is a hub site and when should we use one?
A hub site is a SharePoint site that aggregates navigation, search, and news from associated spoke sites. Use a hub site for each major business unit or division. Attach team sites and communication sites to the hub as spokes. The hub site becomes the starting point for that business unit's SharePoint experience.
How should we prepare SharePoint for Microsoft 365 Copilot?
Three steps are required. First, apply sensitivity labels to every site and library — unlabeled content can overshare through Copilot. Second, audit and remove "Everyone except external users" permissions from sensitive content. Third, configure the SharePoint semantic index exclusions to prevent Copilot from surfacing stale or irrelevant content.
How long does it take to implement SharePoint best practices in an existing tenant?
EPC Group's governance assessment takes two weeks. Implementing the full hub-spoke architecture and sensitivity-label structure typically takes 60 to 90 days for a mid-market tenant (500–5,000 seats). Full Copilot readiness — including semantic index tuning — adds another 30 days.
