We would like to suggest download demo version of Microsoft OST Recovery tool (carry out at no cost) to see the process for how to recover OST files to Outlook PST files. By downloading free utility, users simply can understand its recovery/conversion procedure for OST files.
The trial version of Microsoft Exchange OST Recovery tool works as similar to full edition but, offers some restrictions as performs recovery and save OST files to PST, EML, HTML and MSG file format up to 25 items. For availing the unlimited saving facility, you need to buy complete edition of software.
