Updated September 5, 2025: We have updated the timeline. Thank you for your patience.

Microsoft Purview eDiscovery (Premium) is introducing support for pre-authorized and non pre-authorized export download links, to enhance the reliability and performance of export download.

Introduction

A new capability in Microsoft Purview eDiscovery (Premium) enables organizations to configure export download links as either pre-authorized or non pre-authorized.

  • Pre-authorized links offer faster downloads and maintain session continuity for a specified duration configurable by eDiscovery administrators.
  • Non pre-authorized links require re-authentication after each connection loss and are needed for restricted environments that allow access only to limited Microsoft 365 IP ranges.

This message is associated with Microsoft 365 Roadmap ID 498160.

When this will happen:

General Availability (Worldwide): Rollout begins mid-September 2025 and completes by end of September 2025.

General Availability (GCC, GCC High, DoD): Rollout begins early October 2025 and completes by end of October 2025

How this will affect your organization

This update allows organizations to maintain strict control over data access while optimizing download performance based on environment needs.

What you need to do to prepare

Admins should:

  • Review organizational policies and familiarize themselves with new export configuration options, including link type selection and duration settings.
  • Update internal documentation and training materials to reflect this capability.
