The SYSessential OST to PST Converter is a user-friendly application that converts OST files to PST. The converter supports batch conversion and a complete scan of your data before any operation. There will be no loss of data during conversion, since it preserves the folder hierarchy, sender/recipient addresses, subject of the email, and attachment of contacts, calendar items, images, journals, and other files. Only selective folders, files, or dates need to be exported, rather than the entire OST file migration. This software also recovers orphaned, corrupt, and inaccessible files without using Outlook. It is compatible with all Windows versions.
