I had a Exchange 2003 and BES 126.96.36.199, I then installed a Exchange 2007, gave the BESAdmin full Exchange admin rights + Send as/recive as rights.
I then tryed to install: "Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1" On the BES
But got the message: "Messaging API and Collaboration Data Objects 1.2.1 -- Messaging API and Collaboration Data Objects 1.2.1 cannot be installed with this version of Microsoft Exchange."
How do I solve this?
Is it possible to run a BES with both Exchange 2003/7?
Looking forward to hera from an expert.
