Cigati PST Converter is a Windows application designed to transform Microsoft Outlook PST files into a wide range of formats suitable for archiving, migration, sharing, and data management. It supports both ANSI and Unicode PST files, allowing users to process mailbox data while maintaining the original folder hierarchy and item structure throughout the conversion process.

The software works with complete mailbox content, including emails, contacts, calendars, notes, journals, tasks, and attachments. It offers several export options, enabling information to be saved in formats such as PDF, EML, MSG, MBOX, HTML, TXT, DOC, DOCX, CSV, and other commonly used file types. This flexibility makes it useful for users who need access to Outlook information outside the email client or wish to transfer mailbox content to different platforms.

A built-in preview feature displays mailbox items before processing begins. Users can browse folders, inspect individual messages, and verify selected data before starting the operation. This helps reduce errors and ensures only the required content is included in the final output.

The application includes advanced filtering options for greater control over exported data. Mailbox items can be selected according to date range, sender, recipient, subject, or folder. These filters are helpful when handling large mailboxes and extracting only relevant information instead of converting the entire PST file.

Batch processing support allows multiple PST files to be handled in a single session, saving time when working with extensive collections of Outlook data. Password-protected PST files can also be processed by entering the appropriate credentials, making it possible to access secured mailbox content without changing the original file.

For users planning mailbox migration, the program supports exporting directly to several email services and cloud-based platforms. This reduces the need for intermediate file creation and simplifies the movement of mailbox data between different environments. Throughout the process, email formatting, metadata, attachments, and folder organization are preserved to help maintain consistency after export.

The software includes options to exclude duplicate emails during processing, helping reduce unnecessary storage usage and keeping destination mailboxes organized. Users can also split large output files where supported, making archived data easier to manage and store.

An intuitive interface keeps navigation straightforward for both experienced professionals and first-time users. The step-by-step workflow guides users from selecting the source PST file to choosing the destination format and applying optional filters before starting the conversion.

Compatibility with multiple versions of Microsoft Outlook and Windows allows the application to function across a variety of system configurations. Even when Outlook is unavailable, the program can access offline PST files for conversion, making it suitable for backup restoration, mailbox recovery, document preparation, and long-term data preservation.

Whether the goal is creating readable document copies, transferring mailbox content to another platform, extracting selected information, or maintaining an organized archive, Cigati PST Converter provides a range of features that support different Outlook data management requirements while preserving the integrity of the original mailbox.
