I've been following a million and a half different posts here on EE, but am having some serious issues still with my Exch2k10 Autodiscover settings. Internal non-windows clients (i.e. MAC, iPAD w/mail, etc) are unable to configure their mail settings correctly, as well as anything external (Android, etc.)
Here's a breakdown, I'll try to keep it as specific and short as possible.
Here is the error we receive when we run the
"Microsoft Remote Connectivity Analyzer" at https://www.testexchangeconnectivity.com/
Attempting to send an Autodiscover POST request to potential Autodiscover URLs.
Autodiscover settings weren't obtained when the Autodiscover POST request was sent.
ExRCA is attempting to retrieve an XML Autodiscover response from URL https://DOMAIN.COM/AutoDiscover/AutoDiscover.xml for user TEST@DOMAIN.COM.
ExRCA failed to obtain an Autodiscover XML response.
An HTTP 500 response was returned from Unknown.
All other tests prior to this pass without issue (Certificate / DNS / etc). I've deleted and recreated the autodiscover virtual directory via the Exchange Shell, but the problem hasn't been able to be rectified.
Going to "http://mail.domain.com/autodiscover/autodiscover.xml", it prompts for credentials and then gives me an "Invalid Request, Error 600" - which tells me that the service itself is working.
I've done quite a bit of troubleshooting on this, based on other EE posts - but I'm open to trying anything to get this working, so if anybody has any information on how I can - I'd be more than willing to try their suggestions out.
Google has a plathora of people with the same error code, each with a different solution that worked for them. Unfortunately, I haven't been so lucky. :(
