Collaboration Data Objects (CDO) 1.2.1 with Outlook 2010 and 2013
Many vbscripts use old Outlook / Exchange CDO components for MAPI access. Without CDO you'll get "ERROR: ActiveX component can't create object (MAPI.Session)" error message. Unfortunately CDO works only with 32-bit Outlook 2007. If you're running 32-bit Outlook 2010 or 2013 in either 32-bit or 64-bit OS following might come handy.
