Corporate users often ask how they can convert OST to TXT when OST files become inaccessible due to corrupted profiles, disabled Exchange accounts, M365 shifts, or decommissioned servers. TXT is preferred by compliance teams, auditors, and data analysts because it offers plain text visibility with zero platform restrictions. Manual conversion approaches work only if the original Outlook profile and server connectivity are still active, which is not always possible. A practical alternative is using the SysInfo OST to PST Converter Tool, which is designed for smooth OST data extraction and conversion. The software supports orphaned OSTs, bulk emails, selective folder export, and multiple output choices, including TXT, PST, EML, MBOX, CSV, and others. It retains data integrity, header details, attachments, folder structure, and ensures no email body truncation, which is crucial for audit trails. Additionally, the tool provides preview functionality before conversion, saving time and helping users verify content. IT teams appreciate that the tool reduces manual workload and avoids dependency on Outlook, making the conversion process scalable, accurate, and secure for professional environments.
