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.

Thanks OST PST Viewer (pro), I have been able to restore Outlook archived sent items which were no more visible in Outlook. A seemingly know issue that one should be able to correct using MCFMAPI, but I never succeeded :-( . Thanks the "Export All items" function, I have been able to recreate new .pst files and retrieve hidden files!

I absolutely love this program. With the turn around rate in the job markets now, people come and go, and sometimes important work needs followed-up a year or two from now. OST PST Viewer makes it very simple to do that. Thank you so much! 5 stars!

I absolutely love the Outlook-like interface and this is truly the most complete PST/OST Viewer. It has all the features I could possibly ever need, especially for viewing my older saved OSTs from Exchange accounts.
