One day, due to the sudden termination of Outlook (Outlook-Exchange synchronization is in progress) my OST file get corrupted. To recover that file, I used a manual method called "Export to PST", but failed to access my OST file data. After that, I got your Convert OST to PST software free trial version and it not only helped me to resolve corruption issues, but also allowed to save data into PST file. Thanks a lot.
