Update Rollup 5 for Exchange 2007 SP1 (KB953467)

The hot topic of the day for Exchange is the release of Rollup 5 for Exchange 2007 SP1. A laundry list of fixes (48 in all). Some are worth mentioning:

949968 Unified Messaging does not handle the diversion header correctly in Exchange Server 2007 Service Pack 1
954197 Exchange 2007 CAS cannot copy the OAB from the OAB share on Windows Server 2008-based Exchange 2007 CCR clusters
957978 The OAB generation is unsuccessful and Event IDs 9328 and 9373 are logged in the Application log in a Windows Server 2008-based Exchange 2007 Single-Copy cluster environment

Looks like a couple good fixes to address Windows 2008 compatibility not to mention the UM diversion header fix.
