  • I am currently using Mozilla Thunderbird as my email client, but due to a job change and company policy, I now need to migrate my emails to another platform. I have thousands of important emails with attachments stored in Thunderbird, and I need to convert them into other formats like PST, PDF, MBOX, EML, or HTML for backup, sharing, and future access. I tried manual methods such as copying profiles and exporting messages, but they are very time-consuming and risky. There is also a concern about data loss, email structure, and attachment integrity during conversion. Can anyone please suggest the best and safest way to convert Thunderbird emails to other formats without losing emails, folders, or attachments?
