Autodiscover failed, how to get it resolved?

This is using 2 MS Exchange 2010 servers, 1 being the CAS, and another one is MB/Hub. Autodiscover used to work until probably 3 months ago. It was found not working as we have to resort to manual settings keyin instead of automatic configured. Both exchange servers using SP3

I checked the Microsoft remote test connectivity test, and the result is failed. Please see the results as attached.
The 2nd test is, I using Test Email Autoconfiguration, it also failed. 3rd test, browse to https://autodiscoer.abc.com/autodiscover/autodiscover.html, and result with error - 600. But, other features - OWA, Outlookanywhere, and others are working fine. What could be the problem, and how to solve it?

thanks in advance.

Hi,

https://abc.com:443/Autodiscover/Autodiscover.xml

This is the URL that fails... starting with https (implying port 443 i would think) so try to browse to this URL with a browser and make some changes in the adress until it finds the right xml file.

This you need to adjust in exchange.

BTW: Http 600 means autodiscover service works so ignore that error.

Hi Michael,

Via the exchange powershell module, for a step by step click this link.

look for
