Common Office 365 to PST Export Errors 

  • If Internet Explorer 9.0 or later is being used, the application tries to connect but crashes without displaying an error message.
  • When using other third-party browsers, you receive the following error message: “Cannot Download the application. The application is missing required files. Contact application vendor for assistance”.
  • Sometimes, the eDiscovery PST Export tool fails or becomes unresponsive in the middle of an email export.

Causes of Office 365 to PST Export Errors
