My Outlook 2010 with mailbox size of about 2GB (using Exchange 2010) starts within one second, -if- I uninstal CC Pro. With CC Pro it takes about 30 seconds to start. That is my desktop PC. On notebook, it takes about 60 seconds / 1 second with / without CC Pro :(
I started using "Quick Steps" (macros) instead of CC Pro because of that, but I would be very happy to return to CC Pro if speed would be improved.
