I have tried to setup Exchange 2010 on our server and have been able to use POPcon to get emails to it from an external pop server. However, I can't seem to get the certifcations right. I get SSL cert errors everywhere. I fear it is so screwed up by now that I should just start over. It has been a mess from the start. I took this over after another IT guy was fired. Sadly, 2010 is not my strong suit.

Is there a step by step guide to setting up exchange 2010 and all the certs? Is it possible to drop back and punt and start anew?

And will active sync work if I am using a smart host?
