i installed a new hard drive for a friend and told him to back up all his important files, he backed up his outlook express folders, address book, inbox, sent, etc. only instead of .pst files the ones he backed up are .dbx files. from the file sizes i think they correspond to the folders he wanted but i've never seen .dbx files. is there any way i can import them to outlook or outlook express? any help would be appreciated...🙂
