Most users searches the best tool to convert OST files into PST format. I want to recommend MailsDaddy OST to PST Converter that allows users to export OST files into PST, EML, MSG, MBOX, RTF, Office 365, Live Exchange Server, and many more. It has the ability to recover any type of corrupted OST fiels witohut losing a single bit of information. After the recovery process the application display the preview of complete OST file databases before convetion.
