Shared responsibility sounds like a mature way to run a company, but inside the Microsoft 365 ecosystem, it often means nobody is actually in charge. When everyone is told they own a system, no one is structurally accountable for what happens next, leading to a dangerous ownership vacuum. In this deep dive, Mirko Peters explains why this fundamental gap in digital strategy creates long-term risks for your tenant and your data. 🚀

The video explores how the bystander effect translates directly into enterprise collaboration, where inaction becomes a rational choice for busy employees. We break down three critical incidents that reveal these failures: orphaned teams that persist after project leads leave, external sharing links that stay active for years after a project ends, and retention policies that look good on paper but lack real business logic. You will learn the vital distinction between technical custody held by IT and the business sovereignty required for true data quality and security. 🏢

Mirko introduces a robust service ownership model that moves beyond static RACI charts to create living stewardship. By separating platform, service, and data ownership, organizations can ensure their environment is ready for advanced tools like Microsoft Copilot. Discover how to design accountability directly into your provisioning workflows, use Microsoft Entra as a functional control plane, and implement structural enforcement through Purview and DLP. 🛠️

If you want to turn your Microsoft 365 environment from a liability into a high-performance asset, this session provides the roadmap you need. Please subscribe to the M365 FM podcast and connect with Mirko Peters on LinkedIn for more insights on how technology shapes business reality. 🎧
