Consider the following scenario:
WARNING: The test was unable to log on to Outlook Web Access because of an authentication failure. URL: xxxx Mailbox: xxxx User: xxxx WARNING: The test for URL 'xxxx' failed.
This issue occurs because Exchange Server rebuilds the network credential and uses only the NetBIOS domain name when non-FBA authentication methods are used. Authentication fails because the NetBIOS domain name does not match the FQDN in a disjoint namespace scenario.
To resolve this problem, install Update Rollup 7 for Exchange 2007 Service Pack 1.
