Cigati PST Merge Tool - 2026 Pricing, Features, Reviews & Alternatives

Cigati PST Merge Tool is a specialized Outlook data management utility designed to consolidate multiple PST files into a single unified storage file. It addresses organizational challenges faced by IT administrators and enterprise users who manage extensive Outlook archives. The tool supports all PST formats such as ANSI PST, Unicode PST, and Archive PST, making it suitable for environments running various versions of Microsoft Outlook. It operates without the need for third-party integrations and functions entirely within the local system environment.

The tool provides two consolidation methodologies. The join function preserves original folder hierarchies by adding each source PST file as distinct folder structures. The merge function consolidates all data items into unified folder structures. Bulk addition capabilities allow selection of individual files or entire folders containing PST files. A date range filter enables selective consolidation of email items within specified time periods. All Outlook data objects including emails, calendars, tasks, contacts, journals, and notes can be consolidated with manual selection options. Duplicate entries identified by sender, recipient, subject, and date parameters are removed during processing to optimize storage utilization. An attachment removal feature excludes file attachments when they are not required. Password protection functionality secures the resulting PST file with a custom password.

The application runs on release eleven of the Windows operating system and prior releases. Minimum system requirements include a quad-core processor, eight gigabytes of memory and two hundred fifty-six gigabytes of free disk space. The software generates log files at default system locations with configurable paths for custom storage preferences. A trial version is available that supports consolidation of twenty-five email items to allow evaluation of core functionality. The tool does not process corrupted or damaged PST files and requires recovery of such files prior to consolidation. The tool enforces recommended PST size limits for optimal performance and data integrity.
