Microsoft Purview Data Lifecycle Management
The Purview solution that retains content you need to keep and deletes content you no longer need, using retention policies and retention labels.
Microsoft Purview Data Lifecycle Management governs how long content stays in Microsoft 365 workloads — Exchange mailboxes, SharePoint sites, OneDrive accounts, and Teams messages — automatically retaining or deleting it by administrator-defined rules. It helps meet regulatory retention obligations and keeps stale data from surfacing in Copilot responses. The exam distinction is scope: retention policies act broadly at the workload level, while retention labels apply at the item level and travel with content when it moves. When both apply, the principle of retention wins — the longest retention period takes precedence over a shorter one.
