Hi, Can u verify that ur Exchange virtaul Directory Exchange has Basic authentication. Also what are you using https: or http for your OWA url, if https then can u confirm that SSL is enabled on OWA website. Also verify that services like WWW Service are running.

Hello, Check that in IIS the headers are in place, i.e. mail.yourdomain.tld should be in the headers for the default web site so that when you URL https://mail.yourdomain.tld/exchange you get in. Also, chek if use forms based authentication in the virtual directory properties in checked.

Thanks all guys for helping me alot. My Problem is resolved partially. Actually my Mailbox Store was mounted but my Public folder was not mounted thats why i was getting this error. As i mount my Public Store my users are connecting to OWA but one problem i am facing. Only one user is able to connect to OWA but not others. I also checked the exchange features tab in AD for all users having the OWA is enabled for them I even tried to access users Mailbox via MSoutlook but faced the below error message. (even the user has admin rights on that machine/PC) http://tinypic.com/view.php?pic=2ceedz&s=5 Any comment will be appreciated ________________________________ Thanks Zahid Haseeb zahidhaseeb.wordpress.com
