OST PST Viewer Customer Reviews

Average Rating: 4.8/5 - 280 reviews

“ Just did a download of the PST Viewer and it is SO much easier than trying to load old PST files into outlook. Outlook can be so confusing and makes assumptions that you want to keep the archives mounted. PTS Viewer lets me just peek into my archives - then put them away neatly. Very handy tool indeed! ”
