10 SharePoint Best Practices Every Admin Should Know

SharePoint has long been a cornerstone of enterprise collaboration, document management, and intranet strategy. But as the platform evolves, from classic sites to modern communication hubs, from on-prem to cloud-native experience, so too must your approach to administering it.

Whether you’re overseeing a sprawling enterprise tenant or just getting your hybrid environment under control, there’s no room for “set it and forget it” anymore. From security gaps to sprawl to permission chaos, SharePoint can quickly go from business enabler to operational liability without disciplined oversight.

Here are 10 SharePoint best practices every admin should know, compiled from the latest Microsoft guidance, insights from certified Microsoft partners, and real-world enterprise deployments.

1. Design with Governance in Mind—From the Start

Let’s start here: SharePoint site sprawl is real. And it’s usually the result of launching without clear governance policies in place.

Before a single site is created, define:

• Who can create sites (and what kind—Team vs Communication)
• Site naming conventions
• Retention and deletion policies
• Who owns the site and how ownership will be maintained

A formal governance strategy doesn’t mean choking productivity, it means giving users the freedom to collaborate safely and consistently. Microsoft’s SharePoint Governance Planning guide emphasizes balancing control with autonomy, especially in M365 environments where self-service site creation is enabled.

Pro Tip: Use Microsoft’s SharePoint Governance Checklist and consider automating site provisioning with Power Automate to enforce consistency.

2. Implement a Tiered Permission Model

SharePoint permissions can be deceptively complex. One of the biggest mistakes admins make is overusing unique permissions or granting access ad hoc. It leads to permission sprawl, audit headaches, and potential data leaks.

Best practice? Stick to group-based access control:

• Use Microsoft 365 groups to manage access at the site level.
• Avoid breaking inheritance unless absolutely necessary.
• Keep permission levels consistent (Read, Edit, Full Control).

Pro Tip: Regularly audit permissions using Microsoft Purview or third-party tools to surface excessive privileges and stale access.

3. Standardize Site Architecture for Findability

If users can’t find what they need, they’ll store it somewhere else. SharePoint isn’t just about storage, it’s about structured knowledge management.

Every SharePoint environment should have a clearly designed architecture:

• Use hubs to organize related sites by function, department, or region.
• Define metadata and content types for common document formats.
• Create navigation standards that are intuitive and role-based.

Pro Tip: Leverage managed metadata services to standardize tagging across libraries and improve search performance.

4. Embrace Modern Sites and Phase Out Classic Ones

Still clinging to classic SharePoint sites? It’s time to let go. Microsoft has made it clear: the future is modern.

Modern SharePoint sites are:

• Responsive and mobile-friendly
• Easier to maintain and customize without code
• Integrated with Microsoft Teams and Viva

Pro Tip: Use the SharePoint Modernization Scanner from Microsoft to assess what needs to be upgraded and how to modernize your classic sites.

5. Monitor External Sharing Like a Hawk

SharePoint’s sharing capabilities are powerful—but risky if left unchecked.

You need clear policies (and tools) for:

• Who can share externally
• What content types are eligible for sharing
• How long shared access lasts

In Microsoft 365, you can configure external sharing policies at the organization, site, and file levels.

Pro Tip: Turn on expiration dates for external sharing links and use sensitivity labels to apply data protection policies automatically. Monitor activity with Microsoft Purview and Defender for Cloud Apps.

6. Use Sensitivity Labels and DLP to Secure Data

Speaking of labels—classification is your first line of defense in the age of data leaks and compliance fines.

Integrate Microsoft Purview Information Protection with SharePoint to:

• Classify sites and files (e.g., Confidential, Public, Internal)
• Apply DLP (Data Loss Prevention) policies
• Control what can be downloaded, copied, or shared

Pro Tip: Sensitivity labels can also dictate site privacy settings (private vs public) and sharing capabilities, giving you control from creation to deletion.

7. Enable Versioning, But Set Limits

Versioning is a lifesaver—until it isn’t. By default, SharePoint keeps 500 versions of every document. Multiply that across your tenant, and you’re looking at massive storage bloat.

Best practice:

• Keep versioning enabled for traceability
• Set realistic limits (e.g., 50 versions)
• Educate users on restoring previous versions

Pro Tip: Storage in SharePoint is pooled across your tenant. Monitor usage with the Microsoft 365 admin center to prevent overages and optimize capacity.

8. Automate Lifecycle Management

One of the most overlooked areas of SharePoint administration is content lifecycle management. Too often, sites, pages, and documents linger long after their usefulness has expired.

Use Microsoft’s built-in tools to:

• Set retention policies and auto-delete rules for old content
• Archive or decommission stale sites
• Trigger reviews and renewals for site ownership

Pro Tip: Automate content lifecycle with Microsoft Purview’s retention labels and rules, and build workflows in Power Automate for content review.

9. Train End Users (and Power Users)

An admin can build the most secure, structured SharePoint site on earth—and users will still upload a PDF titled “finalfinalFINAL_revised2.pdf” into the wrong folder.

Training matters. Focus on:

• Naming conventions
• Search vs navigation
• Version control and check-in/check-out
• Team vs communication site usage

Pro Tip: Create a SharePoint Champions program. Identify departmental power users and equip them to support adoption at scale.

10. Monitor Usage, Adoption, and Risk

You can’t manage what you can’t see. Use Microsoft 365’s built-in analytics to track:

• Site activity and user engagement
• Sharing and collaboration patterns
• Storage and growth trends

For security and compliance, Microsoft Purview, Defender for Cloud Apps, and Azure AD logs offer critical insights into who’s accessing what, from where, and when.

Pro Tip: Create dashboards in Power BI to report on key usage and security metrics for stakeholders.

Wrapping Up

SharePoint is no longer “just” a file dump. It’s a digital workplace platform, an intranet engine, and a security perimeter all in one. That means SharePoint admins are no longer simply technical custodians, they’re stewards of collaboration, compliance, and user experience.

By following these best practices—rooted in Microsoft’s most current guidance, you position yourself not just as a SharePoint admin, but as a strategic enabler of your organization’s modern work ecosystem.
