Symptoms
After Service Pack 2 is applied to the server that is running Microsoft Forefront Unified Access Gateway 2010, a Microsoft Outlook user successfully authenticates with that server to access Outlook Anywhere. If the user is not in the list of authorized users for the application, Forefront Unified Access Gateway returns an authentication prompt even though the user is successfully authenticated.
In this case, when a user is not in the list of authorized users, you would expect Forefront Unified Access Gateway to return an error to Outlook and Outlook to enter a disconnected state.
Cause
This problem occurs because Service Pack 2 introduced an unexpected change in behavior.
Resolution
To resolve this problem, install Service Pack 4 for Microsoft Forefront Unified Access Gateway 2010.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
