The OST to PST Converter is designed to assist users in converting their OST files into PST format without causing any data loss. It will transfer all of the original information that was stored within your OST file to your new PST file successfully. This program guarantees that during the transfer from one file type to another, all of your original content will remain unchanged; this includes email messages as well as attachments and contact lists/categories, calendar items, to-do lists, and notes. The original folder structure will also be preserved for all items in the same manner in which they were originally stored so that nothing is physically altered or left behind during the discharge of this function.
