An MBOX file must first be converted to a compatible format, such as PST (Personal Storage Table), in order to be manually opened in Outlook. There are multiple steps in this procedure, and it can be rather complicated. Start by importing the MBOX file into an email client such as Mozilla Thunderbird. After importation, an add-on like ImportExportTools NG must be installed in order to export Thunderbird emails in EML format. After that, you may transfer these EML files into Outlook by using the drag-and-drop functionality, which will create a new folder for them. Finally, use Outlook's export feature to export this folder to a PST file.

However, this manual process comes with challenges. It is time-consuming, requires multiple software installations, and involves a steep learning curve, especially for non-technical users. Additionally, there is a risk of data loss or corruption during the conversion process.
