Average Rating: 4.8/5 - 295 reviews
"I was very frustrated with accessing pst files with Outlook. Outlook's instructions are confusing and can cause all kinds of problems if not done right. Hours and hours of wasted time. What a relief to be able to view PST files with OST PST Viewer without using Outlook."
