The hidden cost of data sprawl: How Microsoft 365 training fixes your information chaos

Are your Teams channels spiralling out of control? Are your SharePoint libraries cluttered with duplicate documents? Or maybe your OneDrive folders are overflowing with files no one ever uses? You’re not alone. Industry research varies in its estimates of the degree to which data held by companies is redundant, obsolete or trivial (commonly referred to as ROT). With some claiming it could be as much as 85%. In other words, a significant portion of what sits in your Teams, SharePoint and OneDrive adds little to no value to your business. Yet, this wayward data quietly drives up your storage costs, slows down productivity and increases compliance and security risks. 

Without structured Microsoft 365 data governance training and clear retention policies, ROT data multiplies over time. In this article, we outline the hidden risks of unmanaged data sprawl and why generic, feature-focused tutorials aren’t sufficient.

How Microsoft 365 tools can create unintended information chaos

Virtually every organisation relies on Microsoft 365 to collaborate, store and manage information. These tools transform the way we work. While Teams enables real-time collaboration, SharePoint centralises knowledge, and OneDrive provides flexible file access from anywhere. In a hybrid working world, these capabilities have become increasingly indispensable.

But the very flexibility that makes Microsoft 365 so transformative also makes it difficult to control at scale. An extra Teams channel created for a short-term project. A SharePoint folder added ‘just in case.’ A OneDrive file never moved into a shared library. Individually, these actions seem harmless, but over weeks and months, these small actions add up, and information is scattered everywhere. Channels are abandoned, libraries fill with duplicate versions, and important information becomes impossible to find. 

This is how data sprawl begins.

What is Microsoft 365 data sprawl and why does it matter?

Data sprawl in Microsoft 365 is the uncontrolled proliferation of files, sites and information across Teams, SharePoint and OneDrive. More than simply ‘untidy storage’, it’s fragmented, poorly structured information spread across multiple digital locations without consistent governance.

For employees, this means:

• Searching far longer than necessary to find files
• Uncertainty about where documents should be stored
• Recreating work that already exists

For the organisation, the consequences are more serious:

• Poorly structured data undermines AI and analytics initiatives
• Retention policies are inconsistently applied
• Sensitive information can be exposed or retained longer than required
• Regulatory and audit risks increase

Data sprawl isn’t something that happens overnight, but instead it builds quietly over time. Buying more storage may contain the volume, but it doesn’t address the root cause. The real solution is addressing behaviour and information management at the source. This is why Microsoft 365 data governance training is essential.

The hidden risks: Why controlling data sprawl in Teams and SharePoint is a priority

The flexibility of Microsoft 365 is one of its greatest strengths. Teams channels can be up and running in minutes. SharePoint sites can be created effortlessly. Everyone can share and upload content and collaborate across departments. This agility is powerful. But without governance, it’s also a source of risk. 

The rapid growth in content across a Microsoft 365 ecosystem creates ROT (redundant, obsolete and trivial) data. This is:

• Redundant: Duplicate or unnecessary versions of files
• Obsolete: Outdated or inactive content
• Trivial: Temporary or low-value information with no business purpose

Left unchecked, ROT data can create serious hidden risks, including: 

• Spiralling storage costs as unnecessary content accumulates
• Compliance exposure when retention rules are not enforced
• Security vulnerabilities from orphaned or over-permissioned data
• Productivity loss as staff waste time searching or recreating work
• Unreliable analytics and AI outputs due to inconsistent data structures

Effectively controlling data sprawl in Teams and SharePoint requires practical skills. Staff need to know how to organise, share and manage content in a way that prevents the accumulation of ROT and reduces these hidden risks.

How SharePoint helps control Microsoft 365 data sprawl

SharePoint is the backbone of document management within Microsoft 365. It underpins Teams, integrates with OneDrive and acts as the central control point for information architecture. 

When properly structured and well used, SharePoint can provide the information architecture to control data sprawl. However, SharePoint can only deliver this when it’s structured intentionally, and content is stored logically and consistently.

Key elements of a strong SharePoint information architecture include:

• Clear Teams channels and SharePoint site hierarchies – everyone knows where projects and documents belong, reducing confusion and lost files.
• Standardised naming conventions and metadata – files are easier to find, and searches return accurate results.
• Retention policies and lifecycle management – old or irrelevant content is archived or removed automatically, keeping the environment organised without constant manual effort.

This structured approach improves operational efficiency while also reducing compliance risks and the likelihood of uncontrolled data accumulation.

The role of expert SharePoint training in taming information chaos

Long-term control of Microsoft 365 data sprawl depends on changing behaviour. When employees understand why structures exist and how to use them correctly, they are far more likely to apply them consistently, embedding governance into daily work habits.

Go Tech Training’s expert SharePoint training for users goes beyond feature demonstrations. It focuses on practical skills and information architecture best practices that help prevent sprawl before it starts.

Through hands-on exercises, employees learn to:

• Navigate SharePoint confidently, understanding core features such as sites, libraries, lists and pages – and personalising navigation for faster, more intuitive access.
• Master SharePoint lists, adding, editing, deleting and restoring items while organising information through sorting, filtering and grouping.
• Manage documents effectively in libraries, including version control, editing and restoring files to reduce duplication and confusion.
• Create and customise views, both personal and public, to improve visibility and make structured information easier to access.
• Enhance collaboration and integration, using alerts, co-authoring, check-in/check-out functionality and seamless integration between SharePoint, Teams and OneDrive.

Armed with this knowledge, information governance becomes second nature. Teams work together with greater confidence, content is easier to find, duplication is reduced, and compliance becomes manageable rather than an ongoing headache. 

Next steps: How to take control of your data sprawl with expert-led Microsoft 365 training

Data sprawl often only starts to feel urgent when it becomes expensive, risky or disruptive. But the reality is, the longer data sprawl remains unmanaged, the greater the losses – in productivity, in unnecessary storage spend and from compliance failures. 

By combining SharePoint expertise with broader M365 compliance training, businesses can tackle the root causes of data sprawl rather than just masking the symptoms. 

Go Tech’s expert-led training is designed for organisations that want more than a feature demonstration. It equips teams with the practical skills, information architecture best practices and compliance awareness that creates lasting behavioural change. And the results are measurable:

• Reduce storage and duplication
• Improve search and findability
• Strengthen compliance
• More reliable and advanced performance from AI and analytics

If your organisation is experiencing uncontrolled growth across its Microsoft 365 environment (or if you want to prevent it before it becomes a problem), acting now can save time and resources down the line.
