From outlook express on the user properties when I set the option "My server requires authentication" only then my exchange server checks the authentication and allow the authenticated users to access mail.
But the problem is when I uncheck the options "My server requires authentication" it also allows the user to send and recive mail. My outlook settings isTools-Accounts- User-Properties-Server-IncomingIMAP-(10.10.10.10 Exchange serverIP; where IMAP is configured.OutgoingmailSMTP(10.10.10.10 Exchange serverIP)
My aim is to allow authenticated user to send mail using outlook express while the user is out of office.
My schenario is PIX-FE-BE exchange cluster uisng exchange 2003.
Please suggest me what configuration I am missing for my exchange
