Converting MBOX files to use as EML or EMLX is possible using an email client or a third-party tool. There is a common method to convert emails that involves using Mozilla Thunderbird, an email client that supports MBOX files. To convert MBOX emails to EML, one can import the MBOX file into Thunderbird mail and then use the drag and drop feature to place all the desired emails into a folder created on the desktop, which will automatically convert all the emails to EML format. In case of EMLX used by Apple Mail, the step is similar but requires importing MBOX into Apple Mail first and then exporting the emails as EMLX. However, users have another option to choose, namely using the BLR MBOX Conversion Tool to easily convert all MBOX files to EML/EMLX formats.
