It began with a familiar cry for help: “We have run out of SharePoint storage… what do we do now?"

A quick check usually suggests buying more storage, but a deeper look often reveals a very different story. In many tenants, storage limits are reached not because users are creating more content, but because SharePoint quietly accumulates unnecessary versions, retains content under Purview retention, preserves files under eDiscovery hold, and stores large volumes of inactive or cold data that no one is using.

This session goes beyond the basics and explains how SharePoint storage is actually consumed, using real-world patterns seen across Microsoft 365 environments. You will learn why versioning, retention, and holds inflate storage; how to set effective Version History Limits without sacrificing recoverability; how to identify high-growth sites; and how Microsoft 365 Archive can shift inactive SharePoint sites into low-cost storage tiers while freeing capacity for active collaboration.

We will break down five proven strategies you can implement to optimise storage, reduce cost, improve governance and avoid unnecessary storage purchases.

What you will learn
1. The technical impact of versioning, retention and holds on SharePoint storage.
2. How to reduce storage consumption using Version History Limits.
3. How to identify and manage high-growth or inactive SharePoint sites.
4. How Microsoft 365 Archive frees storage by moving cold content into low-cost tiers.
5. How to build a practical, scalable storage optimisation model for your organisation.

You’ll leave with a clear, practical set of strategies to cut waste, free capacity, and take control of your SharePoint storage footprint with confidence.
