Kernel OST to PST Converter is a file conversion software that transforms Outlook OST files into PST format. The tool recovers emails, contacts, calendars, attachments, notes, tasks, and other mailbox items from corrupted, orphaned, or inaccessible OST files. It maintains the original folder hierarchy and formatting integrity throughout the conversion process while supporting bulk conversion without size restrictions. The software includes selective item conversion using filters, preview capabilities for recovered content, and options to export data to multiple formats including MSG, EML, PDF, and HTML. Users can search for specific emails within OST files, split oversized PST files into smaller manageable files, and migrate data directly to Office 365, Exchange Server, or IMAP servers. The tool works with all versions of Outlook and Exchange Server.
