Actually i did know that, i'm sorry i didnt mean to leave that part out.
Actually this weekend we are updating to 4.1, so i'm not worried about the 4.0 SP4 part.
I guess i'll upgrade the BES to 4.1, then install ESM 2003 + SP2

The only way to properly register the mapi32.dll files it to install the Exchange System Manager tools on the BlackBerry Enterprise Server.

SP4 is the only service pack in 4.0 that supports Exchange 2003 sp2 (6.5.7638.x).
