Do you use an Anti-Virus product to scan outgoing emails ? If yes, access the AV product and switch off scanning outgoing mail.

Check your username.

Right click on mail account in Folder pane and select 'Settings' At bottom of left Pane, click on 'Outgoing Server (SMTP)'

This will show a list of all your smtp outgoing servers. select the one you use for the account. UserName: it is usually your full email address, but some only use the part before the @ symbol. Check the spelling. Make sure there is no full stop at the end.

Use 'EDit' button to faciliate editing. click on all 'OK's
