This Error event indicates that Microsoft® Outlook Web Access did not read and update its configuration settings from the Active Directory® directory service for the Outlook Web Access virtual directory and Internet Information Services (IIS) Web site specified in the event description. This event may occur if the Web site that hosts the Outlook Web Access virtual directories was removed but the directories still have references to the Web site.

To resolve this error, follow one of these steps:

• Rename the Web site back to its original name.

• Restore Internet Information Services (IIS) metabase configuration settings from backup.

  Note   For more information about how to back up and restore the IIS metabase, see Microsoft Knowledge Base article 324277, How to Create a Metabase Backup by Using IIS 6.0 in Windows Server 2003.

If the Web site must use a new name, follow these steps:

1. Remove all the Outlook Web Access virtual directories before renaming the site.

2. Re-create all previously deleted Outlook Web Access virtual directories under the newly renamed Web site.

   Note   For more information about how to remove and replace an Outlook Web Access virtual directory, see New- and Remove-OwaVirtualDirectory.
