Recently, I've gone through an informative article that explains the best solution to open MBOX file in Thunderbird. Here, you will get the detailed guide of the manual method to perform this conversion process effectively. However, the manual methods are quite complicated to perform as it involves a high risk of losing the data.

In that case, you can use the Cigati MBOX Converter Tool that helps you to backup and transfer your MBOX file to Thunderbird, Office 365, Gmail, iCloud, Hotmail, and many other email clients. Additionally, this utility has a user-friendly interface that provides a smooth working experience to its users. It also facilitates its users to save their MBOX files into various file formats such as PST, PDF, EML, EMLX, CSV, etc. You can download and run its free trial version to analyze its performance.
