We have been using BES 4.1(5) for a while now and it has been a resource hog on exchange due to high number of MAPI calls. I have heard that BES 5.0 is even worse. the comparison i heard is that BES 4.1 is makes MAPI calls equal to 5 outlook clients per BB user and BES 5.0 makes MAPI calls equal to 10 outlook clients per BB user.
can someone confirm if it is true? is BES 5.0 is really that bad in MAPI calls and for exchange performance. ?

thanks
