<p style="text-align: justify;">PST to MBOX conversion is useful when moving Outlook emails to email clients that support the MBOX format, such as Thunderbird. The easiest approach is to use a reliable PST to MBOX conversion tool that can process PST files while maintaining email content, attachments, and folder organization. Before converting, it is recommended to create a backup of the original PST file. Choose software that supports large PST files and provides a simple interface so the conversion can be completed with minimal technical steps.
