Auto Configure not prompting for credentials

Hi Folks,

I've a problem where users of Outlook on XenApp cannot configure an email profile. It just times out. I access the same XenApp server/user account from a Published Desktop or RDP the profile configures fine. 

The Outlook Auto Configuration tool works identically in both scenarios except for the last step. On the Published Desktop I am prompted for domain credentials and then sent the Autodiscover XML file. However, over a XenApp session Auto Configuration never prompts for login details, although the log say differently, and the attempt fails.

I turned on Outlook logging and captured Autodiscover logs for both scenarios (identifying information is changed to NWTraders)

I have the Autodiscover methods which use Active Directory turned off because the Exchange service is not on my domain or a Trusted domain. So we are relying on the HTTPS method only

Hi,

Based on the information you provided, the issue was caused by an Autodiscover failure. To troubleshoot the issue, I suggest you post the question in Exchange forum:
