For efficient and seamless conversion, I recommended the MailsDaddy MBOX To PST converter software. That enables complete data integrity during the conversion time without any change in metadata properties, original folder structure, and text formatting. Users can convert MBOX files into many formats including PST, MHTML, EML, RTF, HTML, Office 365 and Live Exchange. It provides a filter option that helps users filter their email by To, From, Subject Date, etc. This software works with Netscape, Apple Mail, Mozilla Thunderbird, Entourage, Eudora, Gmail, Webmail, Seamonkey, and many more email clients. Capable of working with all Windows OS new to old.
