- Product
- Office 365 / Microsoft Edge
- Device & OS
- not provided
- Scenario
- Exporting search results using the eDiscovery Export Tool in Microsoft Edge.
- Observed behavior
- The eDiscovery Export Tool fails to launch or returns a location error because ClickOnce support is disabled by default in the browser.
Ensure you are using the official Microsoft Edge browser, as Microsoft does not support downloading eDiscovery results via third-party extensions or unsupported browsers.
Enable ClickOnce Support in Microsoft Edge
Since recent versions of Microsoft Edge disable ClickOnce by default, manually enabling this browser flag is required to launch the export tool.
The eDiscovery Export Tool relies on Microsoft's ClickOnce deployment technology. You must enable native ClickOnce support within Microsoft Edge's hidden flag settings to proceed with your data export.
Launch Microsoft Edge, type 'edge://flags' into the address bar, and press Enter to open the experimental features page.
In the search box at the top of the Flags page, type 'ClickOnce' to locate the specific setting.
Find 'ClickOnce Support' in the list, click the dropdown menu next to it, and change the status from 'Default' to 'Enabled'.
Click the 'Restart' button that appears at the bottom of the screen to apply the changes, then attempt to launch the eDiscovery Export Tool again.

Frequently Asked Questions
Why does the eDiscovery Export Tool fail to launch in Chrome or Firefox?
The eDiscovery Export Tool relies on ClickOnce technology, which Microsoft natively supports only through Microsoft Edge. Third-party browsers are not equipped to handle ClickOnce applications natively in this context.
Can I use third-party extensions to enable ClickOnce in Chrome?
No, Microsoft explicitly states that third-party extensions or add-ons for ClickOnce applications are not supported for exporting eDiscovery search results.
What should I do if the tool still fails after enabling ClickOnce?
If ClickOnce is enabled and the tool still fails, ensure your Microsoft Edge browser is updated to the latest version, clear your browser cache, and verify that your Office 365 compliance center account permissions are properly configured.
