how to import large MBOX file to Thunderbird?

[akshat262001]

Hello Everyone,
I’m looking for a reliable tool or method to import large MBOX files into Thunderbird efficiently. My current situation involves handling an MBOX file that’s over 3GB in size, and I’m facing multiple challenges during the import process. I’ve tried using Thunderbird’s native tools and the ImportExportTools NG add-on, but the process either freezes midway or takes an unreasonably long time to complete.
The primary issue seems to be the size of the file, as smaller MBOX files import without any problems. However, with larger files, the process is painfully slow, and sometimes Thunderbird stops responding altogether. I’ve also noticed that when the import does work, some emails appear to be missing, which makes me question the reliability of the method I’m using.
I’m wondering if there’s a more robust solution or tool specifically designed to handle such large MBOX files efficiently.

Are there any premium tools or software that can streamline the process while ensuring that no data is lost?

Additionally, I’d like to know:

• Does Thunderbird have a specific file size limit for MBOX imports?
  
• Would splitting the large MBOX file into smaller parts improve the process, and if so, what tools can I use to safely split it?
  
• Are there any configurations or settings in Thunderbird that I can tweak to make the import process smoother for large files?
  
• How do I verify that all emails have been imported successfully after the process is complete?
  

If anyone has faced similar challenges or has a reliable method for importing large MBOX files into Thunderbird, I’d greatly appreciate your guidance and recommendations. Thank you!
