Use the eDiscovery Export Tool in Microsoft Edge

Important

The guidance in this article is for a eDiscovery legacy solution or feature that was retired on May 26, 2025.

Unless you're working directly with Microsoft when using these legacy features for specific short-term scenarios, use the guidance for solutions in the new eDiscovery experience in the Microsoft Purview portal.

As a result of recent changes to the newest version of Microsoft Edge, ClickOnce support is no longer enabled by default. To continue using the eDiscovery Export Tool to download Content Search or eDiscovery search results, you either need to use Microsoft Internet Explorer or enable ClickOnce support in the newest version of Microsoft Edge.
