If you want to open MBOX files in Outlook, this process is not directly supported by Outlook, but can be easily done using the eSoftTools MBOX Converter tool. This tool helps you convert MBOX files to Outlook-compatible formats like PST or EML, which can then be opened in Outlook. To get started, first download and install the eSoftTools MBOX Converter Tool. Once installed, open the tool and click the "Add File" button to select your MBOX file. After selecting the file, choose PST as the output format, as this is the format Outlook uses. Click the "Convert" button to start the conversion process. After the conversion is complete, you will have a PST file that can be easily imported into Outlook. Simply open Outlook, go to File > Open & Export > Import/Export, choose "Import from another program or file", and then select the converted PST file. After importing, you will have access to all your MBOX emails right in Outlook. This method is simple and effective for anyone who needs to transfer MBOX files to Outlook.
