More Knowledge for Copilot. Less Clutter in SharePoint.

Microsoft 365 Copilot is only as good as the content it can access. As a result, more and more data is being migrated into SharePoint — often via a simple lift-and-shift approach, dragging years of ROT data (Redundant, Obsolete, Trivial) along with it. We've been there too: lift-and-shift looked like the fastest option at the time. It turned out to be the more expensive one, once storage costs and Copilot quality both suffered.

The result? Rising storage costs, bloated content repositories, and Copilot responses based on outdated, duplicated, or conflicting information.

We'll look at how SharePoint storage really gets calculated, and the options Microsoft 365 provides to manage content intelligently instead of simply buying more storage. Drawing on real tenant migrations, we'll build a practical framework:

Reduce – Govern – Archive – Buy.

By the end, you'll know how to give Copilot more of the right information while keeping your tenant lean, well-governed, and cost-efficient.

Topics:
• How SharePoint storage is actually calculated
• Why lift-and-shift migrations can negatively impact both storage costs and Copilot quality
• The biggest hidden storage consumers: versions, retention policies, and ROT data
• Using auto-versioning, lifecycle management, and governance effectively
• Microsoft 365 Archive: when it makes sense and what it really costs

Ideal for IT admins, M365 leads, and decision-makers responsible for both Copilot rollout and SharePoint cost management.
