Using a professional tool for converting an OST file to a PST file is the most efficient and secure method. Manual methods usually do not work when the OST file cannot be accessed or if it has been disconnected from the server. A good solution that works well is the
FixVare OST to PST Converter software. FixVare converts an OST file into PST format while keeping all of the information contained in the original OST file (including all e-mails, contacts, calendars, and attachments) intact and free from data loss. The program supports all versions of Outlook and Windows, and allows users to view their data before conversion. The easy-to-use interface of FixVare makes it easy to use by both technical and non-technical users alike.
