I'm installing Exchange 2010 and am having a small problem with AD users and computers. On my old exchange 2003 server if I ran the AD users and computers MMC there would be a number of options pertaining to exchange. In addition users that I created there would also have an associated exchange mailbox created as well. On the 2010 server this isn't the case, I see no exchange tabs in AD and when I create a user a mailbox is not automatically created either. Any idea what I'm missing?
