VSPL OST Converter efficiently convert OST mailbox data into PST format, allowing users to access their emails independently in Outlook. To move the OST mailbox, install and launch the software, add the OST file, and let the tool scan all mailbox items including emails, contacts, calendars, tasks, notes, and attachments. After previewing the data, select PST as the output format and choose the desired destination location. The software maintains original folder structure, email formatting, and metadata during conversion. It supports orphaned, encrypted, and large OST files without requiring an Exchange connection. With its user-friendly interface and advanced conversion engine, VSPL OST Converter software ensures accurate and hassle-free OST mailbox migration to PST format.
