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.

Ost Viewer is more efficient than outlook to manage mails from multiple e-mail addresses

Excellent software. Works like a charm, but free version only views. To do anything with the view you need to upgrade

The program free version worked for me to retrieve pst files from 10 years ago without outlook even on the computer I was using. Now I'm ordering the pro version so I can print the attachments.

I had some important data buried in an old OST file. After trying multiple "solutions" online to open the OST file in Outlook--none of which worked--OST PST Viewer made it extremely easy to open the OST file and recover the data.
