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.
