Thunderbird – Export from Win7 32bit to Win7 64bit

data transferemailexportimportthunderbird

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:

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:

[General]
StartWithLastProfile=1

[Profile0]
Name=default
IsRelative=0
Path=(Give The Complete Path To Your Profile Here)
Default=1
