As I mentioned in an earlier post, I was recently caught out deploying a new organisation running Server 2008 R2. As our only DCs were R2 boxes we opted to run our AD at that functional level only to find that the latest Exchange 2007 packages (SP2) were incompatible.
Microsoft have now posted updates to the BPA files which will allow installation with this configuration, the english versions to which are linked below:
To use the above just right click and ’save target as’ as the links are to the xml files themselves unpackaged which will otherwise be rendered by your browser. Then all you need to do is drop them in to the Setup\ServerRoles\Common\<language> of your installation directory – those installing from the DVD media will need to copy the DVD to local storage on the machine so they can drop the files in and make use of the fix.
Other language versions and more information is available here.
