Many organizations have successfully migrated large volumes of documents into SharePoint. File shares, legacy ECM systems, and on-premises SharePoint environments have all been consolidated into Microsoft 365.
But once the migration is complete, a new challenge often emerges: much of that content lacks the metadata needed to make it searchable, governed, and usable.
Without metadata, documents are difficult to find, classify, or manage at scale. This creates what many organizations are now experiencing as “metadata debt” — large repositories of valuable information that remain unstructured.
This challenge was the focus of our recent webinar, Introducing Metadata Enrich – Structure & Get Value from Existing SharePoint Content, where we explored how organizations can apply metadata to existing SharePoint content and unlock the full value of their information.
The Hidden Problem of Metadata Debt in SharePoint
Many organizations assume that once content is migrated into SharePoint, the hard work is done. In reality, migration often exposes a new governance challenge.
When documents are moved from file shares or legacy systems into SharePoint, they frequently arrive without meaningful metadata. Instead, organizations inherit:
- Deeply nested folder structures
- Inconsistent naming conventions
- Duplicate files across libraries
- Documents with little or no classification
The result is a growing repository of unstructured content.
Over time, this creates metadata debt — the accumulation of documents that lack the metadata needed for effective governance and discovery.
Without addressing this debt, organizations struggle to:
- Locate critical documents
- Enforce retention policies
- Support compliance requirements
- Enable automation and workflows
The challenge of unstructured SharePoint content is widespread. In fact, during our recent webinar on metadata enrichment, we asked attendees about the current state of metadata usage in their SharePoint environments.
The results highlight how common the problem is:
-
35% reported relying mostly on folders with minimal metadata
-
30% said metadata is defined but inconsistently used
-
24% described metadata as limited or siloed
-
Only 11% said they are actively improving their metadata strategy
In other words, nearly nine out of ten organizations are still struggling to apply metadata consistently across their SharePoint repositories.
These results highlight why many organizations are now exploring metadata enrichment as a way to structure existing SharePoint content and reduce metadata debt.
Why SharePoint Migrations Often Leave Content Unstructured
Content migrations are often focused on moving data quickly and safely, not restructuring it.
As a result, many organizations migrate content with minimal changes to its original structure. Common migration patterns include:
Preserving legacy folder structures
Instead of applying metadata, organizations often replicate folder hierarchies from file shares. While this approach simplifies migration, it does not provide the flexibility or scalability that metadata offers.
Limited metadata applied during migration
Migration projects typically prioritize speed. Applying metadata to millions of documents during migration can be complex and time-consuming.
Lack of consistent classification models
Different teams often organize documents in different ways. Without a shared taxonomy, metadata quickly becomes inconsistent.
The result is a SharePoint environment that contains the right information — but lacks the structure needed to manage it effectively.
Why Metadata Is Essential for Modern SharePoint Environments
Metadata plays a critical role in how SharePoint functions as an information management platform.
Properly structured metadata enables organizations to:
Improve search and discoverability
Metadata allows users to filter, sort, and locate documents quickly, even in very large repositories.
To learn more, see our three-part post: A Practical Guide for Metadata in SharePoint.
Support governance and compliance
Retention policies, records management rules, and classification frameworks often rely on metadata to identify the correct lifecycle for documents.
Enable automation and workflows
Automation tools such as Power Automate rely on metadata to trigger workflows and route documents to the appropriate processes.
Prepare content for AI tools
Emerging tools such as Microsoft Copilot rely on structured content to generate accurate responses and insights.
Without metadata, AI systems struggle to understand document context or relevance.

Why Fixing Metadata Manually Doesn’t Work at Scale
Applying metadata manually works well when documents are created — users can classify content as they upload or generate it.
But applying metadata after the fact is much more difficult.
Organizations attempting to fix existing metadata challenges quickly encounter several barriers.
- Large volumes of content – Repositories often contain hundreds of thousands or millions of documents.
- Inconsistent naming conventions – File names may not clearly indicate document type, owner, or subject.
- Limited user capacity – Expecting employees to review and tag historical content manually is unrealistic.
- Governance gaps – Without automation, metadata quality often degrades over time.
Because of these challenges, many organizations postpone addressing metadata debt — allowing the problem to grow.
What Is SharePoint Metadata Enrichment?
SharePoint metadata enrichment is the process of applying metadata to existing content in order to improve structure, discoverability, and governance.
Unlike traditional metadata implementation, which focuses on tagging documents as they are created, metadata enrichment focuses on retrofitting metadata onto existing documents.
This approach allows organizations to:
- Add metadata to existing SharePoint documents
- Improve document classification
- Enable better search and filtering
- Prepare repositories for governance and automation
Metadata enrichment helps transform large repositories of unstructured files into organized, searchable information systems.
Introducing Metadata Enrich: Structuring Existing SharePoint Content
To address the challenge of metadata debt, Colligo introduced Metadata Enrich.
Metadata Enrich helps organizations structure existing SharePoint content by applying metadata to documents at scale.
Instead of relying on manual tagging, organizations can enrich content by:
- Identifying documents lacking metadata
- Applying rules to classify documents
- Assigning metadata automatically
- Improving the structure of existing repositories
This approach enables organizations to quickly improve the usability and governance of their SharePoint environments.

Real-World Use Cases for Metadata Enrichment
Metadata enrichment can provide immediate value across many scenarios.
Structuring content after file share migrations
Organizations that migrate large volumes of files into SharePoint often find that their content lacks consistent metadata. Enrichment helps restore structure.
Improving governance for legacy repositories
Adding metadata enables organizations to apply retention policies and compliance rules more effectively.
Preparing SharePoint for AI and Copilot
Structured metadata helps AI tools understand document context and relationships.
Making historical documents searchable
Metadata enrichment can significantly improve search results by enabling filtering and categorization.
Best Practices for Metadata Enrichment in SharePoint
Organizations implementing metadata enrichment should consider several best practices.
- Start with high-value repositories – Focus on libraries that contain critical business documents.
- Align metadata with governance policies – Ensure metadata fields support compliance, retention, and classification requirements.
- Use automation where possible – Automated metadata enrichment enables organizations to scale efficiently.
- Maintain consistent taxonomies – Standardized metadata improves usability and reporting.
- Monitor metadata quality over time – Governance processes should ensure metadata remains accurate and consistent.
Common Questions About SharePoint Metadata Enrichment
SharePoint metadata enrichment is the process of adding metadata to existing documents in order to improve search, classification, and governance.
Yes. Metadata can be applied retroactively to existing content using enrichment tools or automation processes.
Metadata allows users to filter, categorize, and locate documents more efficiently within large repositories.
AI tools such as Copilot rely on structured metadata to understand document context and deliver accurate results.
