Recoving Deleted email in Thunderbird

Thunderbird only deletes email when it "compacts" it's folders.
To restore deleted (pre-compacted) email in Thunderbird, locate the email store under...

C:\Documents and Settings\YOUR USER NAME\Application Data\Thunderbird\Profiles.

And open the .MSF file (there will be no association)...

Open it with notepad and do a global replace for
“X-Mozilla-Status: 0009″ replacing it with “X-Mozilla-Status: 0″
and save the file.
