Detailed technical explanation
How to think about this question
Under the hood, Data Lifecycle Management uses retention labels and policies that apply to items at the item level, leveraging the Unified Labeling client and the Microsoft 365 Compliance Center to enforce rules based on creation date, last modified date, or custom triggers. In a real-world scenario, an organization can automatically delete emails older than 7 years in Exchange Online while preserving legal hold items, ensuring both compliance and eDiscovery readiness without manual intervention.
