📖 What is Microsoft Purview Data Lifecycle Management?
Microsoft Purview Data Lifecycle Management is the framework used to manage the entire lifespan of data, from creation to deletion. It encompasses retention policies and labels to ensure data is kept for necessary periods and deleted when no longer required.
"Student, this is the broader strategy that includes both retention and deletion. It's about balancing legal requirements with the 'right to be forgotten'."

🔑 What are the Key Concepts of Microsoft Purview Data Lifecycle Management?
- ▸ Retention Policies apply broad rules across entire locations, such as all Exchange mailboxes, ensuring data is preserved for a minimum duration.
- ▸ Retention Labels provide granular control, allowing users or admins to apply specific lifecycle rules to individual files or emails.
- ▸ The 'Retention' phase prevents premature deletion, while the 'Deletion' phase ensures data is purged to minimize legal and storage risks.
- ▸ Disposition Review allows designated reviewers to manually approve the permanent deletion of data once a retention period has expired.
- ▸ Preservation Hold libraries in SharePoint store original versions of documents when retention labels are applied, preventing permanent data loss.
🎯 How does Microsoft Purview Data Lifecycle Management appear on the MS-102 Exam?
You may be asked to determine whether to use a retention policy or a retention label when a company requires a global 5-year hold on all corporate emails.
A scenario might describe a need to apply different retention periods to specific documents within a single SharePoint library, requiring the implementation of retention labels.
Expect questions about the 'Precedence' of retention settings, specifically how the system handles a conflict between a broad policy and a specific label.
❓ Frequently Asked Questions
What happens when a retention policy and a retention label are both applied to the same item?
Microsoft 365 follows a specific precedence: the shortest retention period is ignored, and the longest retention period wins. If one is a delete action and the other is a retain action, retention always takes precedence.
How does Data Lifecycle Management differ from eDiscovery holds?
Lifecycle management is a proactive, automated strategy for general data hygiene. eDiscovery holds are reactive and targeted, preserving specific data for legal investigations regardless of existing lifecycle policies.
