I understand now.  I'm sorry my reply wasn't any help.  My understanding is that the employer has no way of updating the employee's email address for their Workforce account after the invite has been sent.    The only solution I was able to come up with for my employee has been to scan and email their paystub to them using the email address the Workforce invite should have been set up as.  Of course, they won't have access to their W2s or other past paystubs, but I was never able to get a workable solution from any QB customer service I've contacted.  Good luck.
