Exchange 2010 and pop3/smtp outlook account

Hi,

I have installed exchange 2010 in test environment and configured a test account as POP3/SMTP. but outlook is keep asking for password.

if i configure outlook as exchange account it work fine. or i have to do the following,

Tools --> Account Settings--> More Settings --> Outgoing Server -->
"Log on to incomming mail server before sending mail"

is there any way to bypass this option. I don't want to use the above options,

thanks,
