As I was looking around today for some information about how to find a solution for forwarding address to an external email, I found this site http://www.msd2d.com.
Unfortunately, you have to actually have an account to be able to see anything on it. however, the good news is that it’s all free. there are a lot of useful tips and references there. For most people this is gibbly gunk. .. but for those of us who have an interest in Exchange, SQL or Sharepoint in any way, this might be a good site to visit.
