When you create a new Microsoft Outlook 2010 profile, you receive the following error:
This error occurs when Outlook tries to connect with your Microsoft Exchange server. For example, see the following screen shot:
This problem occurs when both of the following conditions are true:
To resolve this problem, use either of the following solutions.
When you create an Outlook profile by using the Auto Account Setup process, a Lightweight Directory Access Protocol (LDAP) query is first performed to look up the user who is currently logged on. Then, this user's e-mail address and Exchange server information is returned from Active Directory Domain Services. This LDAP query is successful in Outlook 2010, and the query is not the cause of the error message that is mentioned in the "Symptoms" section.
When you click Next in the Auto Account Setup process to connect with your server and finish creating the profile, Outlook 2010 has some new additional code (This code is not found in Outlook 2007) to make sure that you do not add the same Exchange account two times. This new code assumes that Autodiscover succeeds. And, it pessimistically assumes that if Autodiscover fails, you might be trying to add a duplicate Exchange account. Because Autodiscover is expected to fail in almost all configurations that involve an Exchange 2003 mailbox, this new code generates the 0x80070057 error.
In this scenario, you can force a successful Autodiscover connection by using a local Autodiscover.xml file and some registry data. This registry data forces Outlook to use a local Autodiscover.xml file for Autodiscover queries.
The following is an example Autodiscover.xml file:
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
