Easy to use and well-designed, this program is a joy to use. Even a non-technical person will be able to use this application without any difficulty. Once the whole database has been exported from OST to PST without losing any data, the file may be retrieved. The hierarchy will be kept while all files and folders are aligned. No data is lost during the conversion process since the OST Converter program performs the conversion in a precise and fast way. No matter how unread an email was before conversion, it will keep its original format after conversion.
