It is always quite tough to select good software among many. I was also in same situation when I needed to convert an .ost file to Outlook compatible PST format. After searching for many free solutions I found an article with the list of a few good converters. Most of free converters were online and need to upload OST file to their server for the conversion. My file was quite large 26 GB and not possible to upload it to the server for free conversion. Finally I converted my entire mail using a paid solution that was developed by mails daddy. It was a great help for me. You guys may also find a suitable solution from the list
