We'll help your employee change their email, Mirabel.

When your employee accepted your invitation in Workforce, their Intuit account was also created. Thus, if they need to update their email address, they need to do it on their end. Then, you can just update their email on your record, so they can receive their future pay stubs in their Workforce account.

Please have your employee follow the steps in this article: How to change the user ID or email address for QuickBooks Workforce. After that, you can update your employee's email in QuickBooks.

If you need more help, you can always go back to this thread. Your employee can also post questions in the Community if they need help.
