I have several accounts in the Thunderbird I was using from 2007-2009 and I cannot open them on a new Thunderbird Install, I've tried the following procedure but it does not work. On old hard drive: Your profile should be located here:

   C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\
   Copy the Roaming/'Thunderbird' folder 


On new computer: Assuming you have installed Thunderbird and it has run once to create a default profile, but as yet no mail account or you want to use the old mail account settings, address books etc.

   Exit Thunderbird - it should not be running. 

Access default profile location:

   C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\
   Delete that new 'Thunderbird' folder from the 'Roaming' folder.
   Then paste the copied 'Thunderbird' folder (from old hardrive) into the 'Roaming' folder.
   Start Thunderbird.

just what do you have? those instructions are for an old profile, not some mail files.
