We currently run Exchange 2003 SP1, and also have Blackberry server. Up to now our understanding was that we need to apply the standard DST O/S fix to the Exchange server, but would only need to install the CDO patch if we had applications that use CDO – and Microsoft was only releasing the CDO patch for Exchange 2003 SP2 (KB937653).
Instead of migrating now to Exchange SP2 now, could we use KB940123?
This is the correct fix for an Exchange 2003 SP1 installation.
In this case the customer is installing it on on Blackberry Exchange Server (aka BES). We suggest that customers contact RIM to find out what RIM recommends and supports for their products in this scenario.
Otherwise, the customer may update the Exchange 2003 components on the BES computer to SP2 and then apply 937653 (as RIM states in the link).
