Hi all Can this be done where you prevent users to browse their mail on their mobile devices? I see in their AD profile on the Exchange Features tab is a option Outlook Mobile Access option. What does this option do? W e do not want users to do be able to see their e-mails on their personal devices thanks in advance

If you are allowing users to access OWA, then no, you can't stop it. While you could block OMA, with the modern browsers on PDA devices, they will almost certainly be able to use the full OWA client. OMA is http://host.example.com/oma and is a plain text version of OWA. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources

or you can add/modify the default.htm document to verify the web browser version and deny access. Pretty sure each mobile browser is easily identifiable thru its version/name
