@thunderbird I haven't used Thunderbird for two years or so now (due to some technical problens that Thunderbird caused with my e mail accounts after reinstallation). I would really like to give it another try, but I need to be able to import my old profile with all the archived messages and address book and so on. Is it possible to just copy and paste a 2 years old profile and use it? This used to be the standard way to migrate to a new machine, but will it work with several versions skipped?
