I have installed OWA and granted 'log-in local' rights to users. When accessing the page I am receiving the initial Outlook Web Access Log on screen. After entering the userid and clicking on 'click here to your personal e-mail account' I am presented with a connect to domain login in prompt. The user name is entered in the format domain\userid followed by the password. However each time OK is clicked on I am re-presented with the domain log in prompt. Please could anyone suggest what needs to be done to correct this authentication problem?
