Setting up mail in outlook - -ERR USER NOT AUTHENTICATED"

Hi



I go to add new email account in outlook

I go to manual set up
choose POP or IMAP

my complete email address as user name and password and all the following setting

Incoming Server Settings:

Incoming Server Name: pop.zoho.com
Port: 995
Require SSL: Yes

Outgoing Server Settings: 

Outgoing Server Name: smtp.zoho.com
Port: 465, SSL or
Port: 587, TLS
Require Authentication: Yes

email client manages to log on to incoming mail server but fails to send a test email message giving the below error details:

"Send test e-mail message: Cannot send the message. Verify the e-mail address in your account properties.  The server responded: -ERR USER NOT AUTHENTICATED"

Please advise how this issue could be solved.

Many thanks
