Autodiscover failed (0x800C8203)

When you run "Test E-mail AutoConfiguration", you get the following result.

Autodiscover to https://<FQDN>/Autodiscover/Autodiscover.xml Failed (0x800C8203)


One of the reasons is the Outlook client cannot find the DNS record of Autodiscover service.

To solve this case, you need to create a DNS record for the Autodiscover service in the DNS server.



Another reason is the Client Certificates setting of Autodiscover in IIS doesn't select "Ignore".


After updating the above settings, the Autodiscover of the Outlook client resumes normal.

    Hi Terry and thank you for this post

    May you please assist me if possible
    Currently I have exchange 2010 and 2013 in the same environment/network and autodiscover seems to work for 2010 but fails for 2013 when I perform the "Test E-mail AutoConfiguration" Test
    I already have both 2010/2013 Host A Record on my local DNS and I've even created an A Host Record pointing to exchange 2010 for now since most of clients reside on it

    What could I be missing

    Thanks in advance

      Hi,
      Have you configured and pointed your autodiscover record to Exchange 2013 CAS?

      There are 2 articles to explain about Exchange 2010 to Exchange 2013.
