CoolUtils Outlook Viewer is a productivity tool that lets users open and view files for MS Outlook such as PST or OST files. Since MS Outlook usually comes packaged with the other apps in the MS Office suite, installing it just to view one or two files is incredibly inefficient. With the CoolUtils Outlook Viewer, you can access those email files without going through as much trouble. The tool can also be used to create email reports, convert emails to EML files, and sort emails. With its easy-to-understand interface, CoolUtils Outlook viewer can be used by virtually anybody. It’s a small and lightweight app that can’t hurt to have around in your PC.
