When you switch to a new computer you often want to move Thunderbird profile to new computer. Especially when you are working on a desktop email client like Thunderbird or Outlook. The same may be required after a hard drive crash for instance.

As it is, we all know that Thunderbird is an open-source desktop email application that is similar to MS Outlook. Thunderbird allows the user to communicate from one or more email accounts and provides business productivity tools like calendars and task lists.

When you upgrade your computer, you want to make sure that your contacts, emails, calendars, and appointments stay with you. Unlike Outlook, there is no in-built feature to export your email and settings in Thunderbird.

Either you need to manually copy your profile folder over to the new machine, or you can take the help of a third-party tool. Both solutions we will describe below to move Thunderbird profile to new computer.

“Hello there, my Thunderbird email client has crashed, which I was using on my old machine. But today I acquired a new laptop, and once again I began using the Thunderbird email software on my laptop. But I need to access prior data, but I don’t know how can I achieve this. Please advise to me the solution that enables me to transfer Thunderbird email to new machine without Thunderbird”
