In Eudora, Files>Import asks me to "select the account I would like to import", & lists as options Outlook Express (which is not installed), & Microsoft Outlook. I states it will import mail, address book & personalities. Choosing that imports no messages.
If I choose Advanced the options are the above 2 plus Netscape Messenger (also not installed). This screen also asks me to locate the .pst file, which I did, as shown in my original message. This option also imported no messages, though there are a number of messages in Outlook.
