A new build of Exchange ’12’ BETA 1 has been released to the Microsoft Connect site. The build (which is called BETA 1 DF3 or Dogfood 3) contains a lot of improvements especially when speaking the Exchange Management Console. Are you part of the BETA program I highly recommend you download the new build from the Microsoft Connect site.
NB
Don’t let the dates shown fool you, as they for some reason haven’t been changed to reflect the new release.
