Hello community,I tried to configure the autodiscover system. I checked- SCN entries with the ADSI edit - DNS name resolvingThe problem is that I tried to configure a Windows Mobile 6.1 mobile phone with the autodiscover function. The mobile phone can not retrieve the settings. So I looked for a solution and found a test page.https://www.testexchangeconnectivity.comThe error I get is:Attempting to Retrieve XML AutoDiscover Response from url https://autodiscover.xx.net/AutoDiscover/AutoDiscover.xml for user Markus.Schuhmacher@xx.net Failed to obtain AutoDiscover XML response. Additional Details No Settings, Error, or Redirect element present in XML responseWhen I open the autodiscover.xml URI for my self I get the following (I read about this; this message should be normal and the autodiscover should work) <?xml version="1.0" encoding="utf-8" ?> - <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> - <Response> - <Error Time="13:20:54.7137485" Id="3007185755"> <ErrorCode>600</ErrorCode> <Message>Ungltige Anforderung.</Message> <DebugData /> </Error> </Response> </Autodiscover>Remarks:The internal and external address is configured (Get-AutodiscoverVirtualDirectory shows valid entries)The test with Outlook in the LAN works.

Please refer this article to further verify the AutoDiscover service and post the output at here Is there an ISA server or else in front of CAS server? How to Configure Exchange ActiveSync Autodiscover Settings

Haha, I defeated the server :).the external URL of the Microsoft-Server-ActiveSync was wrong. I changed this in the Management console (Serverconfiguration --> Clientaccess). Then the test resaults were better; I received a configuration, but still the wrongaddress. So I made a IISRESET then everything works.Thanks for the tipps.By the way. Please answer me one question. At our customer we have got one ISA Server. Something I must change / notice?

J Glad you solved the issue Well, if you want to deploy ISA server into the environment, the articles below can help: Using ISA Server 2006 with Exchange ActiveSync Publishing Exchange 2007 OWA, Exchange ActiveSync and RPC/HTTP using the 2006 ISA Firewall Publishing Exchange Server 2007 with ISA Server 2006 Notes: Mobile devices (active sync) only work when listener authentication is set to Basic (with basic delegation) on ISA
