Retention Policies and Records Management for SharePoint

SharePoint retention policies are essential rules that define how long content is kept and what happens once the retention period expires. These policies protect valuable data, ensure compliance with regulations, and prevent premature or accidental deletion of important information. Implementing SharePoint retention policies is critical for organizations that manage sensitive or regulated data in SharePoint environments. These policies automate lifecycle management, helping reduce legal and operational risks.

Today, regulatory frameworks such as GDPR, HIPAA, and SOX require organizations to demonstrate control over their data retention. Microsoft offers robust tools, including Purview retention, to support organizations in creating and enforcing SharePoint retention policies effectively. These policies are a cornerstone of good information governance and ensure that content is preserved or deleted in alignment with business and legal needs. At the end of this article, there’s a checklist to help you configure, enforce, and manage SharePoint retention policies to protect content and ensure compliance.

Definition:
A SharePoint retention policy is a set of automated rules that govern how long content must be retained and what actions are taken after that period, such as deletion or archival. These policies can be applied to SharePoint sites, libraries, and documents, enabling centralized content lifecycle management.

Why this matters

According to a 2025 Forrester Total Economic Impact™ study of Microsoft Purview, commissioned by Microsoft, organizations that unify data security, governance, and compliance on Microsoft Purview achieve a 30% reduction in the likelihood of data breaches and significant ROI over three years. When combined with SharePoint site and storage policies that automate archiving and deletion of unused content, organizations can substantially reduce storage and infrastructure costs while keeping their environment clean and compliant. Together, SharePoint and Microsoft Purview provide a strong foundation for data management that supports business goals and regulatory requirements.

Understanding retention vs archival

SharePoint retention policies ensure that data remains available and protected for a predefined period, preventing users from deleting or altering it prematurely. Retention typically applies to active content that must be preserved for legal or operational reasons. Microsoft’s Purview retention framework manages these policies across SharePoint and other Microsoft 365 services, providing centralized control.

What is Archival?

Archival is a separate process of moving inactive data to long-term storage for cost optimization and historical reference. Unlike retention, archival does not enforce compliance but supports data preservation. While SharePoint retention policies keep data accessible during the retention period, archival reduces storage burden post-retention.

Key Differences

Criteria	Retention	Archival
Purpose	Compliance and protection	Cost-effective long-term storage
Accessibility	Full access during retention	Limited or slower access
Managed by	Purview retention policies	Archival tools or manual processes
Automation	Automated retention and policy-based deletion	Semi-automated or manual

Real-World Scenario

A financial services firm applies SharePoint retention policies to keep audit documents for seven years as per regulations. Using Purview retention, these documents are protected from deletion during this time. Afterward, they are moved to archival storage to optimize costs while retaining compliance. This hybrid approach balances data protection with storage efficiency.

Common Challenges

Many organizations confuse retention with archival, which risks premature deletion of essential data. Proper application of retention policies using tools ensures content management in accordance with legal requirements.Additionally, misunderstanding these concepts can lead to increased storage costs or compliance gaps.

Clearly distinguishing retention from archival is vital for applying effective SharePoint retention policies that balance compliance with operational needs.

Setting Up Retention Labels and Deletion Rules

Retention labels are tags that apply specific retention periods and post-expiration actions to SharePoint content. Using the Microsoft Purview retention portal, administrators create and publish labels to sites or libraries to automatically manage the lifecycle of content. These labels play a key role in retention policies and can trigger policy-based deletion or disposition reviews.

Types of Retention Actions

• Delete content automatically after retention period.
• Retain content indefinitely.
• Initiate a disposition review before deletion.

Each action serves different compliance and business scenarios, and correct configuration is key to effective SharePoint retention policies.

Creating Retention Labels in Purview

The setup involves:

1. Signing into the Microsoft Purview compliance portal.
2. Navigating to Information governance > Retention labels.
3. Creating descriptive labels with retention duration and post-retention actions.
4. Publishing labels to relevant SharePoint locations.

This enables consistent enforcement of retention policies across the organization.

Event-Based Retention

When retention depends on specific business events (e.g., contract signing), event-based retention labels can trigger retention periods accordingly. This is a best practice within SharePoint retention policies to ensure accurate and compliant data lifecycles.

Example Use Case

A healthcare provider uses Purview retention labels for patient records with a 10-year retention. After the period, policy-based deletion automatically removes records unless flagged for review. This automation helps the organization comply with health data regulations efficiently.

Best Practices

Map document types to appropriate retention labels and use metadata to automate labeling. Regularly audit and update retention settings to align with evolving regulations. These actions reinforce the effectiveness of SharePoint retention policies.

Setting up labels with deletion in the Purview retention section provides automated, scalable lifecycle management according to compliance requirements.

Declaring records and enabling disposition reviews

Record declaration formally identifies documents as official records, blocking them from being modified or deleted until their retention period expires. This is an important step to maintaining the integrity of data, especially legally sensitive information. With Microsoft Purview, organizations can use record declaration as part of their compliance strategy.

How Does Disposition Review Work?

At the end of a retention period, records declaration processes often trigger disposition reviews, where authorized reviewers decide whether to delete, retain, or archive the content. This adds a necessary human control point to automated policy-based deletion, reducing risk of premature removal.

Benefits of Disposition Reviews

• Validates deletion decisions to comply with regulations.
• Provides an audit trail supporting governance.
• Ensures records remain protected until it is safe to dispose of them.

Utilization reviews complement record declarations, providing a balance between automation and oversight.

Real-Life Example

A legal department declares contracts as records with a 7-year retention using Purview retention. At retention expiry, contracts enter disposition review, where legal teams confirm if deletion via policy-based deletion is appropriate. This ensures compliance with legal holds and audit requirements.

How to Enable

Administrators enable disposition reviews when creating retention labels in Purview, assign reviewers, and configure notifications. This setup integrates with retention policies and enhances control over content lifecycle.

Combining record declarations with disposal reviews ensures that critical content is retained and only removed when legally and operationally justified.

Governance best practices for compliance

Effective governance is essential for maintaining compliant SharePoint retention policies over time. Regulations evolve, business needs change, and without governance, retention policies may become outdated or inconsistent. Regular oversight ensures that policies remain aligned with compliance requirements and organizational goals. Governance also promotes transparency and accountability in information management.

Organizations should establish clear procedures for applying and monitoring SharePoint retention policies to ensure compliance with legal and business requirements. Using SharePoint Advanced Management & Lifecycle Tools can strengthen oversight, provide advanced reporting, and enable more granular policy controls.

Developing a Retention Schedule Matrix

The Retention Schedule Matrix details each document type, its retention period, and the corresponding actions within the retention policies. This document serves as a central reference for compliance departments and helps standardize retention procedures. Maintaining and updating the matrix helps ensure ongoing compliance.

Standardizing Retention Labels

Applying consistent retention labels throughout the organization ensures uniform enforcement of SharePoint retention policies. It reduces errors, simplifies audits, and helps end-users understand retention requirements. Label standardization is key to leveraging the full capabilities of Purview retention.

Automating Reporting and Audits

Purview’s automation tools for retention management create reports and audit trails to track retention label enforcement and policy-based deletion results. This visibility helps identify gaps and conflicts in retention policies. Automated reporting reduces manual workload and enables proactive management.

Employee Training and Awareness

Educating users about SharePoint retention policies, the purpose of record declarations, and policy-based deletion principles helps ensure compliance. Trained employees are less likely to bypass policies, either accidentally or intentionally. Ongoing awareness programs help foster a culture of responsible data use.

Success Story

A global corporation unified its previously disparate data retention policies using the Purview storage system, resulting in a 25% reduction in storage costs and faster audit readiness. The initiative increased compliance assurance and operational efficiency, demonstrating governance benefits.

Effective governance practices are essential for effective and sustainable data retention policies that meet regulatory requirements and business objectives.
