Import WLM database from files

Hello,

i'm having a problem on a computer, the "user" got corrupted and a new user had to be created, naturally all the mails vanished(i can see the directories of the WLM store just fine).

how can i "import" the old WLM DB into the new user?, we copied everything from the old user yet wlm opens EMPTY.

ultimately the idea is to transfer all mails to outlook as WLM is unreliable at best and a management headache but i need wlm to open the mail store for that
