I am trying to export my thunderbird mails and mail accounts from my old win7 32bit to a new win7 64 bit.

Both have the same version (16.0.1). Earlier in this situation I just copy the Thunderbird folder found under my user data account (tried both local and roaming), but this is not working in this scenario.

I also tried to use Thunderbird export/import function, but it gives me a blank screen. This is what I am talking about:

What happened when you first tried using the export mode? – Michael Oct 16 '12 at 9:14

Instead of exporting and importing, you could copy all your mail data and profile across. After copying, open %AppData%\Roaming\Thunderbird\profiles.ini in Notepad and update the Path to the directory where your profile is and ensure that Default is set to 1. If you don't have a profiles.ini file, run Thunderbird to create a new profile (you won't be using this profile later and can delete it).

Your profiles.ini should look like this:

Thanks, Ive tried that (as I tried to explain in my question), but it is like Thunderbird does not recognize this - I still have empty thunderbird – Muleskinner Oct 16 '12 at 10:25
Open the command prompt and launch the Profile Manager (using Thunderbird -p - if necessary go to the directory where Thunderbird is installed). In the Profile Manager, choose to create a new profile and note the directory where it creates it. Copy your old mail data into that directory and ensure that this profile is the default. – M K Oct 16 '12 at 10:31
Thanks a lot this solved it - still not sure why it was not working before – Muleskinner Oct 16 '12 at 10:46
