Designed for both individual users and IT professionals, the software handles healthy, orphaned, encrypted, and inaccessible OST files without requiring an Exchange Server or Outlook profile. It converts emails, contacts, calendars, tasks, notes, journals, and attachments to PST, PDF, MBOX, EML, MD, DOCX, CSV, and other popular formats. Users can preview mailbox data before export, apply date-based filters, remove duplicate emails, split large PST files, and organize output using custom folder naming. The software also supports direct migration from OST to Microsoft 365, Gmail, IMAP, and other email services with accurate folder mapping. Bulk processing enables the conversion of multiple OST files in a single operation while preserving folder hierarchy, metadata, read/unread status, and email properties. It supports large OST files without size restrictions and is compatible with all major Outlook editions and Windows versions. The free trial version allows users to export up to 50 items per folder for evaluation before purchasing.
