Given my busy schedule, I often rely on third-party tools to streamline data conversion tasks. Lately, I’ve been using the GoldyTools OST to PST Converter to extract and convert Outlook OST files into PST format. I originally purchased this software last month for OST data recovery, but it has since proven to be a reliable and efficient solution for routine conversions as well.

If you're looking to export Outlook contacts or other mailbox items to a PST file, I highly recommend this tool. It’s fast, intuitive, and delivers consistently accurate results with minimal effort.
