Body (from Message Center)

[Introduction]

We're introducing a new capability in Microsoft Purview Data Lifecycle Management that allows admins to override existing retention policies and delete content from OneDrive and SharePoint Online before the retention or legal hold duration expires. This feature supports organizations managing Copilot-related artifacts—such as Teams recordings and transcripts—independently of OneDrive retention policies, giving admins greater control over how long this content is retained.

This message is associated with Microsoft 365 Roadmap ID 489454.

[When this will happen:]

General Availability (GCC): We will begin rolling out late November 2025 and expect to complete by early December 2025.
