MAPI is a UDP based protocol for communicating with Microsoft Exchange. The BlackBerry solutions for Microsoft Exchange use the MAPI protocol to communicate with Microsoft Exchange.
You must install the Exchange System Manager onto your BES for Exchange server for two reasons:
1. It is required to complete the pre-installation tasks (granting of permissions)
2. You have to open and close the Exchange System Manager on your BES for Exchange server to initialise the MAPI subsystem on that server. If you don't when you go to start the BES you will get MAPI errors (always starting with a "8")
You will also get a MAPI error if you have just created a System Account, normally BESAdmin, and given it a mailbox and don't send it an E-mail BEFORE starting the BES server.
If you do not have an Exchange CD, to install the Exchange System Manager from, I suspect you shouldn't have an Exchange server.
If you get a "module not found" error when you attempt to register the CDO.DLL then copy the CDO.DLL to the \Windows\system32 or \WINNT\system32 (whichever applies to your server) and then type "regsvr32 cdo.dll".
