Un-deleting emails?

How do I retrieve all my emails that I auto archived by mistake :unsure:

They're not in the archive folder in Microsoft outlook express so I can only gather that they've been permanently deleted :ermm:

Is there a program to put all the emails back :whistling

Thanks in advance

I not sure but in Thunderbird you have an option to save on your IPS . Check with them ?

if they're totally removed i don't think you can get them back

i think you have to use some recovery tool .
