What is Cigati OST Converter
Cigati OST Converter is a desktop utility for converting Microsoft Outlook OST (Offline Storage Table) files into other email and document formats for migration, backup, or eDiscovery workflows. It targets IT staff, support teams, and individual Outlook users who need to extract mailbox data when Outlook profiles are unavailable or when moving to different email systems. The tool focuses on OST-to-PST and OST-to-file exports (for example, message formats and common document outputs) and typically runs on Windows environments where Outlook data files are managed.
Focused OST mailbox conversion
The product is purpose-built for converting Outlook OST files rather than acting as a general document editor. This focus aligns with common support scenarios such as profile corruption, mailbox recovery, and migration preparation. It supports exporting mailbox content into formats commonly used for Outlook re-import or downstream processing.
Multiple export format options
OST converters are often used to produce different outputs depending on the destination system or review workflow. Cigati OST Converter is positioned to export to PST and other file formats used for email portability and archiving. This can reduce the need for separate tools when users require both Outlook-compatible and non-Outlook outputs.
Mailbox item preservation features
Tools in this category typically aim to retain folder hierarchy and message attributes during export. Cigati OST Converter is designed for mailbox-level extraction where maintaining structure (folders) and item types (emails, contacts, calendars) matters. This is useful for administrators who need predictable results for re-import or audit review.
Windows and Outlook dependency risk
OST handling is tightly coupled to Microsoft Outlook and Windows profile behavior. Depending on the specific build and scenario, conversion may require Outlook components or may behave differently across Outlook versions and OST encryption states. This can complicate use in locked-down enterprise environments or on systems without compatible Outlook installations.
Limited transparency on validation
For conversion tools, buyers often need clear documentation on supported OST types (IMAP/Exchange/M365), encryption, large-file limits, and fidelity guarantees. Publicly available technical validation details (test matrices, sample outputs, error handling behavior) are often limited for smaller utilities. This makes it harder to assess reliability for regulated or high-volume migrations without a pilot.
Not an end-to-end migration suite
The product addresses file conversion rather than full mailbox migration orchestration. It typically does not provide centralized administration, automated scheduling, chain-of-custody reporting, or connectors that enterprise migration platforms include. Organizations may still need additional tooling for discovery, deduplication, and destination-side import automation.
