Here is my issue, with an Outlook 2007 client if I'm setting up a new profile to an Exchange 2007 server I get prompted for the users password. If I enter it it simply asks me again and again and again. it does not authenticate.
This ONLY happens on the profile creation, if the user has a profile created in Exchange 2003 and is moved to Exchange 2007 everything works just fine.
I can only assume that autodiscover is not seeing the user as being able to read the SCP connection point as a domain user, and is intead using the XML file for "non domain joined clients".
I have the self installed certificate simply because the client here does not own their internal namespace so I can't get a UCC certificate.
I've looked up on the web and I am at the point of ripping my hair out with this issue. I see nothing wrong at all from my perspective and I know that many people have had this issue.
Integrated authentication is checked, SSL is being used, all autodiscover URLS are correct.
