This method can be applied in situations like when you cannot send or receive email as well as if you cannot get the email server to connect. It may be necessary for you to update the email server settings and ensure the settings are correct and working fine on a home computer. To make sure you are using the correct settings, please contact your email provider or ISP to verify the correct email settings for your account. Also ensure you are connected to the Internet.
