But, it can be a time-taking process, in case you have several or large MBOX files.<BR />To simplify, you can go for <STRONG>SysTools Thunderbird Importer</STRONG>. This tool helps you import an unlimited number of MBOX files at once into Thunderbird without losing a single email, attachments, or folder hierarchy. This is a straightforward approach to complete the import process without installing additional files in just a few steps.</P> Fri, 26 Jun 2026 06:12:11 GMT https://connect.mozilla.org/t5/discussions/how-to-import-mbox-to-thunderbird/m-p/130224#M52115 sharmahrsh137 2026-06-26T06:12:11Z
