Have any of you had experience of installing and setting up Server 2008 R2 and Exchange 2010? I'm trying to set up a DELL PowerEdge server to install in a braille library in Africa, and I seem to be hitting one issue after another. While the Server part seems to be OK, Exchange is proving to be a real pain in the whatnot. For example after running the Exchange Best Practices Analyser, it told me that I had an "unrecognised Exchange signature". To add insult to injury, even though I have applied all known updates, to both Server and Exchange, Help on this did not include Exchange 2010. After ages hunting the internet, I find that this is actually a bug in the Analyser tool which will be resolved when SP1 is released later in the year. Even finding where to put the license key is clearly an issue which has defied many professionals it would seem! Server 2003 and Exchange at the office here were an absolute doodle and took me less that a day to set up, but this lot is really taking the biscuit!!
