Why your data deserves more attention than your coffee machine

Your digital desk is overflowing

Imagine if your office no longer had a filing cabinet and every employee stored their documents somewhere else—on their desk, in the kitchen, on the printer. Pure chaos for you? Then welcome to the digital equivalent: without well-designed storage management in Microsoft 365, that’s exactly what happens—pure chaos—only in the cloud.

Microsoft 365 offers a huge range of tools and storage locations: OneDrive, SharePoint, Teams, Exchange Online. But with great power comes great responsibility – especially for IT administrators, compliance officers, and executives. So should storage management be made a top priority, and what is storage management anyway?

Making it a top priority and what exactly is storage management?

Storage management refers to the administration, control, and optimization of storage resources. In the case of Microsoft 365, this involves the large amount of unstructured data that ends up in OneDrive, SharePoint, Teams, etc. For companies, it ultimately comes down to this:

  • Using storage capacities efficiently
  • Managing data lifecycles
  • Avoid redundancies
  • Comply with compliance requirements
  • Keeping costs under control

Let’s put it another way: storage management ensures that your digital data remains organized, secure, and cost-efficient, while ideally meeting compliance requirements. These are all issues that are absolutely in the interests of the company and the entrepreneur themselves, and should therefore be a matter for senior management, or at least involve management.

Why is storage management so important in Microsoft 365?

cost control

At first glance, Microsoft 365 seems like an all-inclusive package. But additional storage capacity comes at a cost—and it’s not cheap. When SharePoint websites are bursting at the seams or email inboxes are running at 99.9% capacity, it gets expensive.

Fun Fact: SharePoint Online starts with 1 TB + 10 GB per licensed user. Sounds like a lot? Not if every department thinks it needs a digital archive..

Compliance & GDPR

Companies are obliged not to store data indefinitely, but at the same time not to delete it prematurely. The trick is to get the timing right.

Efficiency & Performance

The larger the data set, the slower the search. A well-designed storage concept ensures that data is found—not searched for. Fast access times mean more productive employees and happier customers.

Security

Outdated or unstructured data can pose security risks. Phishing attacks often target poorly protected or incorrectly stored information. Storage management helps you maintain an overview and minimize vulnerabilities.

The equation for the solution is simple

Structured storage = Stronger company

Against this backdrop, the following cornerstones of optimized storage management are relevant for you:

  • Treat data in a lifecycle-oriented manner
  • Manage your storage space in a controlled and automated manner
  • Keep information findable and compliant

Does that sound like a lot of work and effort to you? Then we have an ace up our sleeve for you: the “Data Management” module from our Online Compliance Center is the secret weapon for your Microsoft tenant.

The module was developed for companies to regain control over their licensed Microsoft storage—in a structured, transparent, and automated way.

What the module does:

  • Automated storage monitoring: Keep track of how much storage you are using in your Microsoft 365 tenant and how much extra costs you are generating.
  • Lifecycle control: Define retention periods and versioning and have outdated or inactive content automatically archived or deleted.
  • Automated optimization suggestions: Receive automated suggestions to keep your Microsoft tenant lean and implement the suggestions at the touch of a button.
  • Savings potential: Always have an overview of your saved resources, storage, and costs.

In general, it is advisable to install processes alongside a tool that support the goal of efficient storage management through collaboration and cooperation. To help you proceed efficiently, here are our best practices:

How to get started

Step 1

Analyze the status quo

What data is stored where? Who has access to it? How much storage space has already been used?


Step 2

Define guidelines

What content must be retained and for how long? What can be deleted?


Step 3

Utilize automation

The Online Compliance Center allows you to automate workflows and storage rules.


Step 4

Creating transparency

A central dashboard for storage consumption, compliance status, and data movements provides clarity.


Step 5

Introduce training courses

After all, what good is the best solution if no one uses it properly?


A tidy storage space is a safe business

Storage management is not a chore—it is a strategic advantage. Establishing clear rules early on and using smart tools not only saves storage space and money, but also protects the company from legal and operational risks.

The Online Compliance Center makes this possible—simply, intuitively, and with 100% Microsoft 365 compatibility.
