There is this KB article to reference and Outlook 2007 and 2010 ADM files http://support.microsoft.com/kb/2612922. The ADM files attached to the article were greate because they gave a way to disable the different methods Outlook uses to determine autodiscover in Outlook 2007 and 2010.

- SCP object lookup
- Root domain query based on your primary SMTP address
- Query for the AutoDiscover domain
- HTTP redirect
- SRV record query in DNS
