Hi guys, I installed a Exchange 2007 SP3 CAS, HUB and mailbox in a Windows 2008 SP1 server. When I run for the first time outlook 2007 clients, the account autoconfiguration works fine, but after that, the client propt credentials all the time and the test e-mail autoconfiguration also fails. When I join the user to Domain Admins all works fine. I checked de SSL Certificates and the autodiscover intertal url and all that is ok. Can you give me some help. Regards. Emiliano

Hi, Please locate C:\Program Files\Microsoft\Exchange Server\ClientAccess\Autodiscover folder, find the Autodiscover.xml and right click it, select Properties, click Security Tab, ensure the Authenticated Users in that list and has the Full Control. Thanks AllenAllen Song

Allen, yes I already have the authenticated users with full control. I also checked the in the adsi edit the autodiscover container and it has the same privilege.

Hello Did you Created SRV record for Autodiscover in DNS server ? http://support.microsoft.com/kb/940881 Verify the autodiscover using outlook http://technet.microsoft.com/en-us/library/cc539050.aspxThanks Mhussain

Muhssain, I'm not using SRV records because the clients are domain joined. The autodiscover test show me this log.
