MS Outlook suddenly cannot access my prodigy.net email . . .?

Been using Outlook for many years for my prodigy.net (Yahoo!) email.  Last week I get an error message that the server cannot be accessed.  I've gone through the Outlook email settings (in Yahoo! help) three times to access my email account.  No joy.  Has anything changed lately that isn't on the help set up page?
