💡 Our Technical Review in summary
Summary
Microsoft is updating the retention policy for direct export download containers within Microsoft Purview eDiscovery. Effective February 16, 2026, all direct export packages generated from eDiscovery cases will have a strictly enforced expiration period of 14 days from the time of creation. This change is designed to optimize storage efficiency and enhance tenant security by reducing the lifecycle of staged data exports.
Impact
- Export Availability: eDiscovery users will have exactly 14 days to download an export package once the process is complete. After this window, the container will be deleted and will no longer be accessible for download.
- Affected Features: This change specifically applies to direct exports from eDiscovery cases. It does not impact exports generated from Review Sets.
- User Interface: The Microsoft Purview interface will be updated to display a clear banner notification when an export package has reached its expiration date.
- Historical Data: Any exports created prior to February 16, 2026, will follow previous retention logic and will not be retroactively shortened by this update.
- Source Data Integrity: This change only affects the prepared export container; the underlying source data (emails, documents, chats) remains unchanged and protected within the Microsoft 365 environment.
Action Required
- Update Internal Documentation: Revise your organization’s Standard Operating Procedures (SOPs) for legal and IT discovery to reflect the new 14-day download window.
- Communicate to Stakeholders: Ensure that eDiscovery managers, legal teams, and compliance officers are aware of the timeline to prevent the need for repetitive work.
- Establish Download Workflows: Encourage users to download required packages immediately upon completion of the export task to avoid expiration.
- Regeneration Process: In the event an export expires before it is downloaded, admins should be prepared to re-run the export from the original search using the same parameters to generate a new 14-day download link.
