To export Outlook OST to PST, you cannot directly convert an orphaned or inaccessible OST file using Outlooks built-in options. OST files are linked to the original Exchange or Outlook profile, and if the profile is deleted or the server is unavailable, manual export is not possible. In such cases, using eSoftTools OST to PST Converter Software is a reliable solution. This tool allows you to easily convert OST files into PST format without data loss. It supports recovery of emails, contacts, calendars, tasks, notes, and other mailbox items while maintaining folder hierarchy and data integrity. The software provides a simple interface, preview option, and supports large OST files. After converting the OST file to PST, you can open Outlook and import the PST file using the Import/Export feature to access all your mailbox data smoothly and securely.
