Work email no longer working

so a big company had my dad employed through them. got laid off for winter. he called them and they said he'd get a call in a couple of weeks because they had his name down. he called again a couple of weeks later and they told him in a day or so because for sure they were up and running again. he saw the job posted so applied internally as it suggested to ensure his name got on the list. guess who's email no longer works for the portal. ugh. I don't have the heart to tell him..
