I can't seem to import mailboxes into Mail. I just picked up a used Macbook and am trying to import mailboxes from a g3 imac but it's just not working.
First I tried using the Migration Assistant and a firewire cable. I selected to import files and folders from the imac. Once it was finished and I opened Mail, none of my previous emails were there. Only the most recent ones are there.
Next I tried just importing mailboxes through Mail. So I again hooked up the computers with a firewire cable, seleced the import mailbox function in Mail , it seemed to work and then all my previous maiboxes were put in a folder labelled 'import'. So I thought 'great, it worked!' But when I go to any of those mailboxes they're empty! Also when I exit out of Mail and then re-open it, the import folder (and thus, the imported mailboxes) are gone. What's going on?
