true, but when he mentioned 4770 i kind of assumed he meant the client side of the whole exchange. I doubt any server is running a 4770.
sccm can transfer program packages and quite a bit of data using only HTTPS. Dont see too much of a load on even a 1 core 1 threaded VM client.
to be fair, Windows 7 isn't even listed as a supported OS for Office 2003..
and that actually makes a lot of sense because at my old job one of my users was using '03 outlook and it would always freak out when the server guys would bounce Exchange. It couldnt recover on its own.
