User testimonials

Collected across 92 reviews from portals and emails. Two reviews below are unedited.
This Free PST Viewer Tool is amazing, to say the least. It lets me open and preview my PST files without MS Outlook. It makes the entire process completely efficient and independent of any other program installation beforehand. Moreover, this tool provides incredibly unique features that are hard to find in any other tool. Simply put, this utility is justified to be an expert favorite.
I am not an Outlook user, however, I had been sent over 25 PST files to view and sort as a work assignment. This astonishing Microsoft Outlook PST File Viewer has helped me tremendously. Not only did it upload and preview PST files in bulk but also helped me avoid having to install Outlook beforehand. Its dual search settings helped me sort the PST emails in an efficient and hassle-free manner.
