Microsoft Office 365 has become a regular name in mid and large-sized enterprises. It comprises a range of applications, such as Exchange Online and SharePoint, all packaged in a cloud-based suite. As the usage of cloud storage increases, the major concern of the organization becomes data security.

To keep Office 365 data secure, the front-line defense for any cloud system is to save the data on a local system. Microsoft offers an eDiscovery search facility, that you can use to search the content. Additionally, you can export the data into local file formats using the export tool. In short, eDiscovery is an inbuilt program in O365 that export Office 365 mailbox to PST format.

Reasons Why “eDiscovery Export Tool Export Failed with Error”

Many users have observed complaints about Office 365 eDiscovery search not working or failing under various conditions. So, after considering this, we have identified the major points where this tool fails, and we list those situations below:

  • Unsupported Browsers – If you are using any third-party browser other than Microsoft Internet Explorer, such as Google Chrome, etc. You may encounter an eDiscovery export tool not working error. eDiscovery is only supported with Microsoft Internet Explorer. To fix this, you have to add the ClickOnce extension.
  • .Net Compatibility Issue – If you do not have the installation of .Net 4.5 or a previous framework, then you are most likely to encounter, the eDiscovery export tool stuck error. To fix it you have to install .Net 4.5 or a previous framework.
  • Permissions issues – The user attempting to export the data may not have the necessary permissions to do so. This could include permissions to access the relevant mailboxes or SharePoint sites, or permissions to export data from those locations. You will need to check the eDiscovery Manager Role Group and verify that the required permission is allotted.
  • Large data sets – If the user exports data more than 50 GB in size. Then, the eDiscovery tool freezes and does not move the data into PST format properly. Also, the eDiscovery method may struggle to process and export the entire data. Moreover, this can be particularly problematic if the export is being run on a system with limited resources or slow network connections.
  • Network connectivity issues – If the eDiscovery export process is being run over a network with high latency or dropped packets. Then it could potentially cause the export to fail. To fix it, you need to ensure that the network is stable with minimal latency.
  • Incompatible file formats – The export tool might not have compatibility with the file formats used in the eDiscovery process. For instance, if the tool is meant to export data in a specific format, but the exported data is in a different format, the tool might not be capable of processing it.
  • System limitations – The system on which the export tool is being run may not meet the necessary system requirements for the tool. This could include limitations on the amount of available memory or CPU power, or limitations on the operating system or other software components.
  • Local Intranet Zone Setting – The Local Intranet zone includes all the network connections created using the UNC (or Universal Naming Convention) path. If Internet Explorer doesn’t set it up properly, the eDiscovery tool cannot perform well.

Due to these reasons, many O365 users are looking for an alternative to the Office 365 inbuilt export tool. To ensure the safe process of exporting data from O365 to PC, the users are suggested to utilize reliable software.
