MC999442 - Microsoft Purview | Data Lifecycle Management: Retention based on “last accessed” for OneDrive and SharePoint files

Coming soon for Microsoft Purview | Data Lifecycle Management: Admins will be able to apply a retention policy or retention label in Microsoft OneDrive and Microsoft SharePoint for files that have not been accessed by anyone in your organization for a specified period of time. This message applies to retention for Microsoft 365 file types. We will support other file types (non-Microsoft 365) in a future rollout.

This message is associated with Microsoft 365 Roadmap ID 472030.

When this will happen:

Public Preview: We will begin rolling out mid-February 2025 and expect to complete by late February 2025.

General Availability (Worldwide): We will begin rolling out mid-March 2025 and expect to complete by late March 2025.

How this will affect your organization:

This feature will help delete obsolete data, which will improve the quality and relevance of Microsoft 365 Copilot responses.

This feature will be available by default.

After the rollout, admins can use the retention control When items were last accessed when configuring labels and policies.
