Helo I am trying to configure the SMTP engine in Windows Server 2008 to use a TLS certificate. When I right click the SMTP Virtual server --> Properties --> Access Tab. In the secure communications section it says "TLS is not available without a certificate". There is no certificate button to add one. I did some Googling and read that if you use the MMC certificate snapin to manually add a certificate to the Local Machine\Personal store that it will be detected by IIS and this certificate will show up in the SMTP virtaul server properties. Unfortunately this doesn't seem to have happened. I added the certificate via the MMC and then did, IISReset. No certificate. I then tried rebooting the server, still no certificate. Anyone have any ideas how to add this certificate to allow outbound TLS SMTP communciation in Windows server 2008? Thank you.
