Updated: Microsoft Purview | Data Lifecycle Management: New secure workflow to bypass legal holds and retention policies

The rollout of Microsoft Purview’s Priority Cleanup feature, allowing admins to bypass legal holds and retention policies for permanent deletion in Exchange, is delayed from early February to late February 2025. It requires multiple approvals, specific roles, and supports policy simulation for secure data lifecycle management. Updated August 18, 2025: After further review, this has been delayed to a later date. We apologize for any inconvenience. This new feature enables data governance administrators to expedite the permanent deletion of sensitive content from Microsoft Exchange mailboxes, overriding any existing retention settings or eDiscovery holds.

A new role permission “Priority cleanup administrator” is now added to Purview role permissions to enable data governance administrators to use this feature. Priority Cleanup administrators can now set up a Priority Cleanup policy for Exchange to create exceptions to retention principles and e-Discovery holds for specific scenarios. Once administrators are within the Data Lifecycle Management (DLM) Solution on Microsoft Purview, they can visit the Priority Cleanup tab and follow the wizard to set-up this policy. Like auto-apply retention labels, Priority Cleanup supports policy simulation mode, so administrators can check the returned samples in case the policy configuration needs any fine-tuning before enabling the policy. Once set-up, because the deletion by a priority cleanup policy is irreversible and can override existing holds, the […]
