WSUS supports Exchange 2007
Some time ago, I read this on Bink , but only now I was able to see it by my own eyes. I installed a test WSUS server and confirmed that Exchange 2007 is on the list of products that can be updated.
Now that Beta 2 is coming, the most courageous early adopters can rest assured that their Exchange 2007 servers will get the most recent security patches.
Notice that the Forefront line of products also started to appear on the list.
