Outlook 2007 / Exchange 2003 profile setup error, autodiscover-s.outlook.com prompting for credentials.

Hello,

We have an installation of outlook 2007 on one Citrix server, and exchange 2003 on the back end. Whenever a new user attempts to setup their profile, it does populate their name correctly, but when you go to the next screen, a login window appears that has 'autodiscover-s.outlook.com' as the source. No creds will work at this prompt.

We have an autodiscover DNS record for our upcoming Exchange 2010 deployment, but it currently points to an IP that isn't assigned to anything. Could that be causing the issue? We have several other Outlook 2007 instances in the same location and domain that have no issues.

Has anyone seen this issue?

Yes.  Outlook 2007 will do a DNS query and if there is an autodiscover A record in DNS it will try to use it.

To test this, temporarily remove the autodiscover record from DNS, you can always put it back.   If the problem goes away, you have your answer.

If you need an autodiscover DNS record for testing your new Exchange 2010, test it from a workstation that you configure with a host file and put the autodiscover record in the host file.  The workstation will see autodiscover just like it was coming from DNS and it will contact the 2010 server.  You can also test OWA and Outlook anywhere by putting entries in the host file.  That way none of your users are affected until you cut over at which time you will add autodiscover to DNS and change webmail or owa DNS entries, too.

This is from the following web article: "When Outlook 2007 is launched from a client machine it immediately starts searching your DNS server(s) for a host record. If an IP address is found the client will try to access the Web Site....."

Thank you, this is exactly what I needed. A basic understanding of how auto discovery works in 2010. Saved me from making some bad decisions regarding testing of our 2010 server build.
