Is it possible to change the profile secondary email address. The My Profile web page permits changing the primary one, but only deleting the secondary one.
I believe all you can do is delete and add a new one.
I had the same question. During the process to remove the seconday e-mail address it warned that it could not be added later. I needed to remove it to solve a technical glitch per verizon but now I don't think I can add one going forward.
THIS IS NOT SOLVED!
I still have not found way to do this.
As verizon no longer offers email, they may have changed the way to add secondary accounts.
Log in to Verizon website.
I see sub accounts under My Verizon Profile.
