Hi guys and gals

not sure if anyone can help here but I've just done a fresh install on my intel iMac which i've done before with no problems, till now. each time i do a fresh install i copy my mail folder to an external drive. once up and running I copy the mail folder to home/library then open mail create new account and all my previous emails are copied into the inbox. Now i have 4 different email address on this machine and out of the 4, 1 has thrown a wobbly I missed typed the password during setup so it never completed. I then corrected the password, but the old emails didn't copy across. They are still there in the folder.

I've tried drag and drop into mail but no joy, I've tried copying then in to a folder in mail still no joy. So what i need to know is how do i get the emix files to show in mail
