Large Mailbox Size

Microsoft eDiscovery has a maximum size limit for the report. If the mailbox exceeds the size limitation, you will face errors and crashes during the process.

How to Fix Error in Microsoft Office 365 eDiscovery Export Tool

To fix the eDiscovery Export Tool error in Microsoft Office 365, upgrade to the latest Windows and install the .NET framework. Also, you must change intranet settings, use a supported browser, install the ClickOnce extension, and open the outgoing proxy server to fix the problem.

eDiscovery investigates the internal and external information of a member of an organization. Therefore, you must be careful about security updates and network connections.

Here are the ways to fix the error in Microsoft Office 365 eDiscovery Export Tool:

1. Update Windows

Microsoft rolls security updates and patches with the latest version. You need to install the new version to match the compatibility with the eDiscovery tool.

Here is the way to update Windows:

  • Press on the Windows Start button.
  • Search and open Check for updates.check-for-updates
  • Click on Download and install.update-windows

Windows 10 and 11 are both compatible with export tools. After installing the latest Windows update, check Office 365 eDiscovery and see if any error appears.

2. Install .NET Framework

The .NET framework provides enhancements in applications to create and export eDiscovery reports. You need to install the latest update to get the best compatibility support.

Follow the procedure below to install the latest .NET framework:

  • Navigate to the .NET framework download page using a browser.
  • Press on Download.download-dot-net-framework
  • Find the files in your local storage.
  • Install all the .NET framework programs.

Restart your computer after the installation and ensure the eDiscovery tool works properly.

3. Use Internet Explorer or Edge

To export the reports in eDiscovery, you must use the Internet Explorer browser on your computer. Every browser uses IE in the background to download the files.

Currently, Internet Explorer is retired, and the mode has been converted to Microsoft Edge. So, you can use the Edge to access the eDiscovery Tool.

4. Set Up Local Intranet Zone Settings

Microsoft eDiscovery checks the email from Outlook to find related topics. Therefore, you must set Outlook as a trusted site in your local intranet zone settings.

Here are the steps to set up local intranet zone settings:

  • Search and open Internet Options.internet-options
  • Navigate to the Security tab.
  • Press on Local intranet and click on Sites.internet-options-sites
  • Click on the Advanced option.internet-options-advanced
  • Add the following websites:
    • https://*.outlook.com
    • https://r4.res.outlook.com
    • https://*.res.outlook.com
  • Press on Close.internet-options-local-intranet-sites

Now, run the eDiscovery tool, and it should fetch data without any error.

5. Install ClickOnce Browser Extension

When using a third-party browser, you need to use the ClickOnce browser extension to avoid automatic application launch and maintain security measurements.

The ClickOnce extension is available for Google Chrome and Firefox. You will find it on the official extension website.

6. Open the Outgoing Proxy Server

Microsoft eDiscovery uses port 8080 for the outgoing data. You need to keep the port open to avoid time out and maintain the flow of information.

Follow the procedure below to open the outgoing proxy server.

  • Open Windows Command Prompt.
  • Type the following command and click Enter:
netsh winhttp show proxy
  • Paste the following command and press Enter:
netsh winhttp set proxy proxyservername:8080

You must enter the proxy server name in place of the proxyservername—for example, proxy.contoso.com.

7. Reduce Mailbox Size

The maximum mailbox size limit for eDiscovery is 50 GB. You need to ensure the exported data are within the limit.

At that moment, you may see an Export failed with error type FailedToSearchMailboxes message in eDiscovery.

You can separate the mailbox by date or reduce the mailbox size to fit them in the Export Tool.

After completing all the above methods, the error in the Microsoft eDiscovery Export Tool will be resolved.

Ending Note

eDiscovery is an essential tool to find information about a user under the organization and use it to monitor or as proof for legal action.

When the export tool doesn’t work, you can update Windows, install the .NET framework, use a supported browser, open a proxy server, and reduce the mailbox server to fix the error in MS eDiscovery.
