Stellar Phoenix OST to PST Converter

Stellar Phoenix OST to PST Converter—now rebranded as Stellar Converter for OST—is a powerful software solution developed by Stellar Data Recovery to address one of the most common challenges faced by Microsoft Outlook users: accessing data from offline OST files that have become orphaned, corrupted, or otherwise inaccessible. OST (Offline Storage Table) files are created when Outlook is used in conjunction with Microsoft Exchange or IMAP accounts, allowing users to work offline and sync changes once reconnected. However, when the Exchange server crashes, the Outlook profile is deleted, or synchronization fails, these OST files can become unusable. Stellar Converter for OST steps in to recover and convert these files into PST (Personal Storage Table) format, which can be easily imported back into Outlook. The software is designed with a user-friendly interface that caters to both technical and non-technical users. Upon launching the application, users can either manually browse for the OST file or allow the software to auto-locate it from configured Outlook profiles. Once the file is selected, Stellar performs a deep scan and presents a preview of all recoverable mailbox items—including emails, attachments, contacts, calendars, tasks, notes, and journals. This preview feature is particularly useful for verifying the integrity of the data before initiating the conversion. The software maintains the original folder hierarchy and metadata, ensuring that the converted PST file mirrors the structure and content of the original OST file. One of the standout features of Stellar Converter for OST is its ability to handle encrypted and large-sized OST files with ease. The software has been rigorously tested to convert oversized OST files without compromising performance or data accuracy. It also includes an auto-split feature that divides large PST files into smaller, manageable parts to prevent corruption and improve accessibility. For users dealing with multiple OST files—such as IT administrators or organizations migrating email systems—the Technician edition of the software supports batch conversion, allowing several files to be processed simultaneously. This edition also enables direct export of mailbox data to Microsoft 365 or Exchange Server, streamlining the migration process. In addition to PST, Stellar Converter for OST supports exporting data in various formats including MSG, EML, RTF, HTML, and PDF. This flexibility allows users to access their emails and other mailbox items across different platforms and applications. The software also includes advanced search and filtering options, enabling users to locate specific emails based on parameters like sender, subject, date, and message content. Individual mail items can be saved separately, which is particularly useful for archiving or legal discovery purposes. Another noteworthy feature is the ability to save and load scan information. Users can pause the conversion process, save the scan as a DAT file, and resume it later without having to re-scan the OST file. This is especially beneficial when working with large files or limited system resources. The software also generates detailed log reports of the conversion process, providing transparency and aiding in troubleshooting if needed. Stellar Converter for OST is compatible with all major versions of Microsoft Outlook, including Outlook 2021, 2019, 2016, and earlier. It runs on 64-bit Windows systems and requires minimal system resources, making it accessible to a wide range of users. The software is available in multiple editions—Corporate, Technician, and Toolkit—each tailored to different user needs and budgets. While the Corporate edition is ideal for individual users, the Technician and Toolkit editions offer advanced features suitable for enterprise-level deployments. Overall, Stellar Converter for OST is a comprehensive and reliable tool for recovering and converting OST files. Its robust feature set, intuitive interface, and high accuracy make it a preferred choice among IT professionals, businesses, and individual users alike. Whether you're dealing with a single corrupted OST file or managing a large-scale email migration, Stellar provides a seamless and efficient solution to restore access to your Outlook data
