Transfer e-mail messages between different Thunderbird profiles

Question

Is there a way to transfer e-mail messages between different Thunderbird profiles on the same machine? I'm using Linux Ubuntu.

Answer 1

What I would do is to create a new folder Import in the target profile, then a new subfolder called anything arbitrary (eg Temp), to establish the correct folder structure. After this exit Thunderbird and copy all the mail folders from the source profile into the same place where Temp resides (or create links if the folders are large, but this makes the source mails more vulnerable).

When TB is restarted, all the source profile's e-mails will be available as subfolders of Import and e-mails can be selected and copied at will into the target profile's normal folders (the vulnerability is that the e-mails could be moved by mistake, removing them from the source profile if they are links).

After all the required e-mails have been imported, the source profile copies or links can be removed, but not from TB unless they are copies. Finally remove Temp and Import from Thunderbird.
