I've read a lot in forums about calendaring issues etc when moving to Exch 2007, so I just wanted to check that everything was correct before we did.
So far, we have a bunch of Exchange 2003 SP2 servers and 2 BES 4.1.6 servers. We also have Exchange 2007 Hub Transport, CAS and one mailbox server. There are no mailboxes on the 2007 MBX yet apart from test ones.
I have read that Exchange 2007 no longer uses CDO.dll files, so there are no files we need to update when we move mailboxes to 2007? How about the BESAdmin account though - at what point does that need to be moved? First or last, or does it not really matter?
Any help appreciated!
