📖 What is Retention Labels?
Retention Labels are Microsoft Purview settings applied to individual items in SharePoint, OneDrive, and Exchange to control how long a file or email is kept. They ensure that specific data is preserved for a required period or deleted automatically after a set timeframe to meet regulatory requirements.
"Contrast labels with retention policies; labels are applied to specific items or folders, whereas policies are applied to entire containers."

🔑 What are the Key Concepts of Retention Labels?
- ▸ Granular Application: Unlike retention policies, labels are applied to specific items or folders, allowing precise control over individual documents or emails within a site.
- ▸ Retention Trigger Events: Labels can start their countdown based on when an item was created, last modified, or when the label was applied.
- ▸ Disposition Reviews: Admins can configure a review process where a designated person must decide whether to permanently delete or extend the item's retention.
- ▸ Auto-Apply Capabilities: Labels can be automatically applied to content using KQL queries or sensitive information types to reduce manual effort and human error.
- ▸ Conflict Resolution: When multiple labels or policies apply, Microsoft 365 follows a hierarchy where retention always takes precedence over deletion to prevent data loss.
🎯 How does Retention Labels appear on the MS-102 Exam?
You may be asked to determine the best tool for a scenario where only specific documents within a SharePoint library must be kept for ten years, while others are deleted.
A scenario might describe a requirement for a manual classification process where users must tag emails as 'Financial' to trigger a mandatory five-year preservation period.
Expect questions about configuring a disposition review process to ensure that legal experts approve the deletion of sensitive records after the retention period expires.
❓ Frequently Asked Questions
What happens if a retention policy and a retention label conflict?
Microsoft 365 follows the 'Retention Wins' rule. If one setting says keep and another says delete, the item is kept. If both are retention settings, the longest period is applied.
Can users be prevented from removing a retention label?
Yes, administrators can configure labels so that they cannot be removed by the user, ensuring that compliance requirements are met regardless of user action.
