Hi all,
I’ve been having trouble importing large MBOX files into Thunderbird manually, as the process often fails or takes too long. I tried using the SysTools Thunderbird Import Wizard, and it worked well, managing large files without any data loss. However, I’m still looking for more options and would love to hear if anyone has used other tools or methods that can handle large MBOX imports effectively. What has been your experience with importing oversized files into Thunderbird?
