No, because in IE 11 owa is using basic authentication. &nbsp;Again to my question, is there any special configuration so I can use Premium login in IE11. &nbsp;Why is in IE10 or older version shows the option for Premium login, and it doesn't show the option in IE11.<br />
<br />
If using premium login, the compatibility mode might work.

We have OWA 2003 and Exchange 2003. &nbsp;When users go to OWA via IE10 or below, the owa screen has Premium/Basic Client logon option. &nbsp;However, in IE 11, that option is not list of the screen and it only displays the Security Option(Public or Private Computer&quot;.<br />
Here is my questions:<br />
<br />
1. &nbsp;How can I disable the Premium Client Logon option, so all the IE browser has the same look and feel using basic.<br />
<br />
2. &nbsp;How can I make all the IE browser to have the Premium Client Logon in the Logon Screen.<br />
<br />
I think if I have the answer for #1, then the answer for #2 is just the opposite for #1.<br />
Webvpn OWA didn't work well with premium client, it shows &quot;loading&quot;, but it work well with basic authentication.<br />
<br />
Thank you in advance for your help,

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
