Launching FEI Viewer
You can launch the viewer component of Forensic Email Intelligence (FEI) in four ways:
1. Through the Startup Page
Section titled “1. Through the Startup Page”When you launch the main FEI application without any command-line arguments, you are greeted with the Startup Page below. Clicking on the Launch Viewer button launches FEI Viewer.

In this mode, FEI Viewer will be launched without loading any emails for examination. You can drag & drop an email on the viewer to examine it:

2. By Opening an Email Message with Forensic Email Intelligence
Section titled “2. By Opening an Email Message with Forensic Email Intelligence”If you open an EML or MSG file with the Forensic Email Intelligence application, the email will open in FEI Viewer. If Forensic Email Intelligence was already associated with the EML or MSG file extension on your system, then you can simply double-click on the file to open it with FEI Viewer. Otherwise, you can right-click on the file and choose Open with ➫ Forensic Email Intelligence.
3. From The Evidence Grid
Section titled “3. From The Evidence Grid”If you ingested a collection of emails into Forensic Email Intelligence by creating an FEI project, you can launch the project and double-click on an email item to launch it in FEI Viewer. Once the viewer is open, selecting a new item from the Evidence Grid using a single click will load the new item into FEI Viewer. If you close FEI Viewer, you can double-click on an email from the grid to open it again.
In this mode (i.e., Connected Mode), we recommend opening the Evidence Grid in one monitor and FEI Viewer in another, or opening both tools side by side in an extra-wide monitor, so that you can arrange the two tools on your screen without any overlap.
4. As an Email Viewer for Other Forensic Tools
Section titled “4. As an Email Viewer for Other Forensic Tools”If you are working with a forensic suite and encounter some email data that you would like to examine with FEI, you can use FEI Viewer as an email viewer for your forensic suite. This requires that the forensic suite support opening a file via an external viewer application.
