It is important for you to understand the difference between several authentication types Exchange offers for Outlook Anywhere
Basic authentication: If you select this authentication type, Outlook will prompt for username and password while attempting a connection with Exchange.
NTLM authentication: If you select this authentication type, exchange does not prompt users for a user name and password. The current Windows user information on the client computer is supplied by the browser through a cryptographic exchange involving hashing with the Web server. If the authentication exchange initially fails to identify the user, the browser will prompt the user for a Windows user account user name and password. So, when Outlook is trying to connect to Exchange and if the machine is domain joined, there isn’t a need to provide password.
