I am helping a friend's small company with their IT needs and just renewed their self signed exchange certificate. Both the old and new certs show up in the exchange management shell, but only the old cert shows up in Cert Manager MMC on the server. Comparing the two certs in the Exchange mgmt shell, the only real difference is with the RootCAType. The old shows "GroupPolicy", and the new shows "None". How do I get the new cert into the "Trusted Root Cert... Authorities" in certmgr.msc?

A server certificate should appear in the Personal store for the Computer Account of the Local Computer. How did you renew the self-signed certificate? Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
