GAL-related client-only message rule is not applied in Outlook after you apply RU1 for Exchange Server 2010 SP2 in an Exchange Server 2010 environment

Consider the following scenario:

• You create a global address list (GAL)-related client-only message rule by using Microsoft Outlook in a Microsoft Exchange Server 2010 environment.
• You experience the issue that is described in Microsoft Knowledge Base (KB) article 2543850. When this issue occurs, the client-only message rule is not applied.
• To resolve the issue, you apply Update Rollup 1 (RU1) for Exchange Server 2010 Service Pack 2 (SP2) on the Exchange servers in the environment.

In this scenario, the client-only message rule is still not applied. For example, assume that you create a client-only message rule that moves email messages to a specific folder if the sender is not listed in a GAL address book. However, the email messages are still moved when the sender is listed in a GAL address book.
