Outlook is unstable when your files get big. I've wasted days of time and lost lots of data trying to manage the files and archives. OST PST Viewer and PSTSplitter solved all of my problems.

I was very frustrated with accessing pst files with Outlook. The Outlook instructions are confusing and can cause all kinds of problems with Outlook 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.

My company just moved to the Microsoft Exchange, and we had to find the solution to convert the pst files to ost. I have found this program via the internet and it works perfectly, we are considering to buy an enterprise version soon. Thank you 4team corporation! My recommendations.

Looks promising. Leaving a first feedback of the free version. Search options are not similar to that of Outlook, but have to explore some more to understand whether it is powerful. Giving 4 starts now, definitely will consider giving 5 stars if searching is good and I am able to extract attachments.

It worked well, I tried datanumen originally and it was terrible.

I downloaded the free version and it does exactly what I needed it to do.
Installation was fast and easy and I managed to restore 5 months of emails that were previously lost. I cannot thank you enough and I heartily recommend this Product.
