One common issue why your Verizon email not working can be incorrect login credentials, so double-check that your username and password are correct. Another possibility is that there is a problem with your internet connection or with Verizon's servers. Also, try restarting your modem and router and make sure that your email client is properly configured and up-to-date. You can also consider accessing your Verizon email through the webmail portal. Contacting Verizon support if the issue remains.
