The Sysinfo OST to PST Converter Tool is a reliable and efficient utility developed to convert OST files into PST and many other file formats without affecting the original data. It allows users to export OST mailbox items such as emails, contacts, calendars, tasks, notes, and journals while keeping the folder structure unchanged. The software supports conversion into multiple formats, including PST, MBOX, EML, MSG, PDF, CSV, HTML, DOC, and more, and also allows migration to email platforms like Gmail, Office 365, Yahoo Mail, and IMAP accounts.

This tool can process single as well as multiple OST files at the same time and does not require Microsoft Outlook installation to perform the conversion. It comes with advanced features like a preview option, a date range filter, duplicate email removal, attachment handling, and the ability to split large PST files. The software also supports encrypted, orphaned, and inaccessible OST files for safe and accurate conversion.

The converter works with all Outlook versions and is fully compatible with Windows 11, 10, 8, 7, and earlier versions, making it easy to use for both technical and non-technical users.
