I installed Exchange 2010 with SP1 rollup 5 on 2K8 R2 server and am having the following certificate issues.
I have a separate AD server with AD Certificate Services installed to issue certificates.
I generated the request from the EMC for a wildcard certificate, open up the file and copy the contents and paste it into the web based certificate request form from AD server. It creates two cert files, certnew.cer and certnew.p7b.
I use the MMC for Certificates and install the certnew.p7b in the Intermediate Certificate Authorities, then go to the EMC to complete the pending request. It appears to install correctly, but then disappears from the EMC.
I found on this site where others said the GUI is flakey, so I followed the commands using the Exchange Management Shell from this http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_26722561.html
It returns the following error...
The certificate with thumbprint blahblahblah was found but is not valid for use with Exchange Server (reason: PrivateKeyMissing)
Where did I go wrong and how can I fix?
