When your Microsoft Outlook mailbox becomes inaccessible due to a corrupted or offline OST file, retrieving your emails, contacts, and calendar entries can feel like a daunting task.

This lightweight yet robust software specializes in converting OST (Offline Storage Table) files into PST (Personal Storage Table) files—formats that are fully compatible with Microsoft Outlook. Whether you're migrating from an old Exchange server, recovering lost data after a system crash, or simply backing up your Outlook profile, this tool delivers fast and secure results.
Developed by Cigati Solutions, the software has gained popularity since its release on Softonic in June 2024. With over 100,000 downloads and a solid 4.1 rating, it's clear that users appreciate its simplicity and effectiveness. The current version, 20.0, is optimized for Windows 11 and above, ensuring compatibility with modern systems while maintaining performance on older versions like Windows 10 and 8.1. One of its standout features is the intuitive interface—designed with both beginners and advanced users in mind—making the conversion process straightforward, even for those unfamiliar with file formats.
What makes Cigati OST Converter truly valuable is its ability to recover data without altering the original OST file. This non-destructive approach ensures that your source data remains intact, reducing the risk of permanent loss. It also preserves folder structure, email metadata, and attachments, so nothing important gets left behind.
For businesses and individuals alike, this tool offers peace of mind when dealing with critical email archives. Best of all, it’s completely free to download and use, with no hidden fees or trial limitations.

Key Features of Cigati OST Converter – Why It Stands Out
Cigati OST Converter isn’t just another file conversion tool—it’s a comprehensive solution built with real user needs in mind. Its feature set is both powerful and accessible, making it a go-to choice for anyone dealing with Outlook data recovery or migration. One of the most important features is its 100% data integrity guarantee. During the conversion process, the software meticulously preserves the original structure of your emails, contacts, calendars, tasks, and notes. This means your folders stay organized, and no attachments are lost—critical for professionals who rely on accurate record-keeping.
Another standout feature is its batch conversion capability. If you’re managing multiple OST files—common in enterprise environments—you can process them all at once, saving hours of manual work. The tool also supports selective conversion, allowing you to choose specific folders or date ranges to export, which is ideal for minimizing file size and focusing on relevant data. For users concerned about security, Cigati OST Converter includes password protection support, enabling the conversion of encrypted OST files without compromising safety.
The software also provides real-time progress tracking and a detailed log report after each conversion. This transparency helps users verify that the process completed successfully and identify any potential issues early. Additionally, the output PST files are fully compatible with all versions of Microsoft Outlook, including Outlook 2021, 2019, 2016, and earlier.
You can open the converted PST file directly in Outlook, or even import it into other email clients that support the PST format. With its clean, minimalistic interface and straightforward workflow, Cigati OST Converter ensures a hassle-free experience from start to finish. Whether you're recovering from a server failure or preparing for a migration, these features make it one of the most reliable free OST-to-PST tools on the market.

The final PST file is ready to be imported into Microsoft Outlook. Simply open Outlook, go to File > Open & Export > Import/Export, and select “Import from another program or file,” then choose the PST file.
For advanced users, the tool also supports command-line operations for automation, which is useful in IT environments managing multiple user profiles.
