What did they say the setting should be?
Are you required to provide an account and password?
Did you speak to someone in their IT or lookup the configure information on their website?
Are they your email services provider?
Go Daddy is my email provider. They gave me the proper settings. I have an Office 365 exchange server account.
Outgoing Server smtp.office365.com
Connection Encryption TSL
Authentication (Plain Text)
All the settings are correct.
