Hello,

I have tried this solution but it is a time-consuming procedure and have some limitations as well. Using this ImportExportTools, the folder structure of the MBOX file is not maintained. So, Is there any solution using which I can import MBOX files into Thunderbird easily while maintaining folder structure?

Hi,

Yes, there is an alternative solution too i.e. a third party software to import MBOX files into Thunderbird using which you can easily add MBOX file to Thunderbird. Another benefit of using the software is that it maintains the folder structure of file intact.
