In case you missed: Exchange 2003 support retired

In case you missed, last week the mainstream support on Exchange 2003 ended. (As per 4/14/2009). Of course the Extended support is still available until 4/8/2014, which will probably cost you :)

One more reason to go out-with-old and in-with-the-new!
