Hello all,

We are on part two of our rolling migration to Exchange 2007. We successfully migrated Ex2003 to a temp Ex2003 server. The BES server is on a separate standalone server and it rolled along with the change nicely.

We have removed the existing Ex2003 and installed Win2008/Ex2007 and are ready to roll back from the temp server.

I am confused however with Blackberry KB14502 for the move back. I understand the stop the services part and uninstall the Exchange service manager and rename the mapi32.dll and cdo.dll files.

Do I need to install the Mapi CDO objects on the BES server? On the EX2007 server? On both?

Thanks in advance for your help..

MAPI CDO gets installed on the BES.
