Cigati PST File Viewer - 2026 Pricing, Features, Reviews & Alternatives

Cigati PST File Viewer is a standalone email file management application designed to open, read, and view Microsoft Outlook PST Personal Storage Table files without requiring an Outlook installation. The application serves IT professionals, forensic investigators, system administrators, and business users who need independent access to Outlook data files. It addresses the challenge of accessing PST file contents when Outlook is unavailable or when PST files are corrupted, inaccessible, or oversized.

The application supports viewing of all PST mailbox components including emails, contacts, calendars, tasks, notes, and journals. It preserves attachments and metadata properties during the viewing process. The software supports both ANSI and Unicode PST file formats and automatically detects file information such as format type, version, location, and compression status following the scanning process. Users can select from three recovery modes—standard, advanced, and deep—to process corrupted or damaged PST files. The scanning feature reveals mailbox structures in a hierarchical tree format and advanced filtering functions enable data selection based on date ranges. Duplicate email removal and attachment exclusion options assist with targeted data management and detailed log files maintain a record of all operations.

The software offers conversion capabilities that allow export of PST data into multiple formats including PDF, MBOX, EML, EMLX, MSG, CSV, HTML, and DOC. It allows selection of specific folders from the preview panel for conversion and handles PST files of any size without performance degradation or system lag. Batch processing enables handling of multiple PST files simultaneously and password-protected PST files can be accessed when the correct password is provided. The application operates as a standalone solution without dependencies on Microsoft Outlook or other email clients.

The application is compatible with Windows eleven and all previous Windows versions. It requires a modern multicore processor with a clock speed of three gigahertz or above and eight gigabyte of memory. Installation requires five hundred megabyte of disk space plus additional free space equal to twice the input file size. The trial version provides full viewing functionality and permits export of up to fifty items per folder to evaluate conversion functions.
