All,
I've just been successful gettin exchange email after 2 days.
You need your server connection (able to view at least 1 drive on server).
I went to C:\users\public\public downloads and copied ansd pasted the SBS certificate package to my network folder\drive.
Opened IE and Internet Options. Under content tab, certificate, Trusted Root, Import and browse to the network drive you pasted the certificate and Import.
Worked.
