Another Exchange 2013 CU6 issue: Exchange 2007 users cannot sync over Activesync

It seems CU6 is not bringing much luck if you still have Exchange 2007 in your environment. There is yet another issue with this update:

Log Name: Application
Source: MSExchange Common
Date: <edited out>
Event ID: 4999
Task Category: General
Level: Error
Keywords: Classic
User: N/A
Computer: <edited out>

Description:
Watson report about to be sent for process id: 16024, with parameters: E12, c-RTL-AMD64, 15.00.0995.029, w3wp#MSExchangeSyncAppPool, M.Exchange.AirSyncHandler, M.E.A.Handler.LegacyUserAllowedToSync, System.InvalidCastException, 9619, 15.00.0995.026.
ErrorReportingEnabled: True
 

 

For some reason the 2013 mailbox breaks the legacy users sync. Microsoft is aware and working on an interim update. Current workarounds are either forwarding all traffic directly to the Exchange 2007 CAS server or reverting back to a previous update

Update 9/9/2014: A fix is available from Microsoft:
