Frustration with error, can anyone assist? The server is have issues with autodiscover, however not on the Outlook clients. Having an issue with Vipre for Exchange not blocking spam and they are pointing to a autodiscover issue. [PS] C:\Windows\system32>Test-OutlookWebServices | FL Id : 1003 Type : Information Message : About to test AutoDiscover with the e-mail address Administrator@mydomain.com Id : 1007 Type : Information Message : Testing server EXCHANGE.internal.mydomain.com with the published name https://mail.mydomain.com/EWS/Exchange.asmx & . Id : 1019 Type : Information Message : Found a valid AutoDiscover service connection point. The AutoDiscover URL on this object is https://mail.mydomain.com/autodiscover/autodiscover.xml. Id : 1013 Type : Error Message : When contacting https://mail.mydomain.com/autodiscover/autodiscover.xml received the error The remote server returned an error: (401) Unauthorized. Id : 1006 Type : Error Message : The Autodiscover service could not be contacted. In my research, I have found that the directorys have the correct read access. If I go to https://mail.mydomain.com/autodiscover/autodiscover.xml, the username/password login box appears. If I goto https://localhost/autodiscover or https://localhost/autodiscover/autodiscover.xml I am not prompted for U/P and get this XML output: <?xml version="1.0" encoding="UTF-8"?> -<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> -<Response> -<Error Id="3007185755" Time="12:44:27.5320723"> <ErrorCode>600</ErrorCode> <Message>Invalid Request</Message> <DebugData/> </Error> </Response> </Autodiscover> I have run the commands from MS Article 940726 and set the clientaccessserver uri as noted. Still getting the (401) Unauthorized error. The SSL cert is with godaddy, and it was keyed with this command: New-ExchangeCertificate -GenerateRequest -keysize 2048 -domainname exchange.internal.mydomain.com,mail.mydomain.com,autodiscover.internal.mydomain.com -FriendlyName mail.mydomain.com -privatekeyexportable:$true -path c:\cert_exchange.txt Again, all services outside are working (active-sync, OWA, OOF, POP) and the internal Outlook clients do not have any connecting issues. Thnks in advance.

Also note, this is Server 2008 R2 and Exchange 2007 Std SP3

Hi Mark, Per the information, I donot think there are some issue with the autodiscover service, but for the error information you could resolve it as below: Disabled IPv6 and disabled Loopback check followed the KB articles: http://support.microsoft.com/kb/896861 http://support.microsoft.com/kb/929852 Like you refered all the services working well for external and interual users, it would not be with the services issue.
