If you want to replicate your offline Outlook email data on another computer, you have two options: you can configure Outlook and reconnect it to the original server to generate a new OST file, or—more efficiently—you can use a professional tool like the GoldyTools OST to PST Converter to convert your existing OST file into a PST file.


Microsoft has stated that unlike PST files, OST files cannot be directly imported into Outlook. However, using a reliable conversion tool like GoldyTools, you can effortlessly convert OST files into multiple formats, including PST, PDF, HTML, DOC, and DOCX—while preserving the original folder structure and data integrity.
Expert Method for Converting OST to PST Using GoldyTools:

1. Download and install the GoldyTools OST to PST Converter on your computer.
2. Launch the software and click "Browse" to locate and load your OST file.
3. Select the mail folder(s) you want to convert.
4. From the format dropdown menu, choose your desired output format (e.g., PST).
5. Set the destination path where the converted file will be saved.
6. Click the "Convert" button to begin the process.

This approach provides a fast, accurate, and user-friendly solution for transferring or recovering Outlook data—especially when the original account is no longer accessible.
