How can I get my BES Server to see two exchange servers (exchange 2k3 and a new 2k7) using the installed software holding the licenses. Permission already given to 2K7 and ready to run in mixed mode

Which version of MAPI32.dll do you have on the BES? You will probably have Calendar issues with one of the Exchange servers as Exchange 2003 does not like Exchange 2007 CDO and vice versa. Are both Exchange servers in the same Exchange Org?

As long as you have MAPI installed you should be able to see both Exchange servers. MAPI makes the BES Exchange world go round

I have installed the MAPI from MS download center as stated by the exchange 2K7 installation guide.
I can not find the way to set both servers to the same BES software. At the “Edit MAPI “ only one can be used

As long as both servers are in the same Exchange org then you only need to point the MAPI to server holding the BESAdmin mailbox. Other than that the BES will see all Exchange servers in that Org, the BES won't show it but it can see them because of MAPI. Also, have you configured permissions on both Exchange Servers? If not that could be a reason why you're having issues, all Exchange servers need to have permissions set on them.
