SYMPTOMS

Microsoft Exchange Server 2007 Client Access Servers (CAS) cannot copy the offline address book (OAB) from the OAB share on Windows Server 2008-based Exchange 2007 Cluster Continuous Replication (CCR) clusters. The result of this situation is that OAB data on CAS servers may be stale. Or, you may be unable to download the offline address list because it is unavailable. Additionally, the following event is logged on the CAS server:

Source: MSExchangeFDS
Event ID: 1021
Task Category: General
Level: Warning
Keywords: Classic
Description:
Process MSExchangeFDS.exe (PID=xxxx). Could not find directory <OAB share location> This is normal if the directory has never been generated. Otherwise, make sure this directory and share has read permission for the "Exchange Servers" group.

CAUSE

This problem occurs because Windows Server 2008 clustering introduces the concept of share scoping. In share scoping, a file share is specific to either the node name or to one of the cluster name objects that the share hosts. In this case, if the share is shared by the node name, it cannot be accessed by the Clustered Mailbox Server (CMS) name.

RESOLUTION

Download and install Update Rollup 5 for Exchange 2007 Service Pack 1. For more information about Update Rollup 5 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
