- Product
- Microsoft 365 eDiscovery Export Tool
- Device & OS
- not provided
- Scenario
- Attempting to launch the eDiscovery Export Tool via Microsoft Edge, Google Chrome, or Internet Explorer to export Microsoft 365 search results.
- Observed behavior
- The tool will not start, fails to launch, or crashes unexpectedly depending on the browser being used.
Ensure you are using a supported operating system and have administrative privileges on your computer to install required frameworks or modify advanced browser security settings.
Install .NET Framework 4.5+ and Enable ClickOnce in Edge
The eDiscovery Export Tool requires the .NET Framework and ClickOnce browser support to execute properly.
Microsoft 365 eDiscovery relies on ClickOnce deployment technology. Modern browsers may block this by default, and missing framework dependencies will immediately cause the tool to fail upon execution.
Download and install Microsoft .NET Framework 4.5 or a newer version from the official Microsoft website if it is not already installed on your system.
Launch Microsoft Edge and type 'edge://flags' into the address bar to access the advanced experimental features menu.
Search for 'ClickOnce Support' in the flags search bar. Change the dropdown menu setting from 'Default' or 'Disabled' to 'Enabled'.
Click the 'Restart' button at the bottom of the Edge browser to apply the changes, then navigate back to your Microsoft 365 compliance center to re-launch the eDiscovery Export Tool.
Configure Local Intranet Zone Settings
Incorrect Windows security zone configurations can prevent the export tool from downloading or running correctly.
Resolve Outgoing Proxy Timeouts
A timeout in your proxy connection can interrupt the eDiscovery Export Tool's communication with Microsoft servers.

Frequently Asked Questions
Why does the eDiscovery Export Tool crash in Google Chrome?
Google Chrome does not natively support ClickOnce applications, which the Microsoft 365 eDiscovery tool relies on. To fix this, you must either install a third-party ClickOnce extension from the Chrome Web Store or switch to Microsoft Edge.
Can I run the eDiscovery Export Tool without installing .NET Framework?
No, the eDiscovery Export Tool strictly requires Microsoft .NET Framework 4.5 or a later version to be installed on your computer. Without it, the application will immediately fail to launch.
How do I know if my proxy settings are blocking the export tool?
If the eDiscovery tool attempts to start but hangs indefinitely or returns a network timeout error, your outgoing proxy server might be restricting the connection. Temporarily disabling your proxy or having your network administrator whitelist Microsoft 365 URLs can confirm and resolve this.
