Importing new SSL cetificate Exchange 2007

Posted on 2015-02-02
Last Modified: 2015-02-10
Hello, I'm having problems importing our new mail SSL certificate into Exchange 2007 using the PowerShell. The error I'm getting is -

The certificate with thumbprint (number here) was found but is not valid for use with Exchange Server (reason: PrivateKeyMissing).

I've scanned the web and have tried the certutil -repairstore command to no avail. The only thing that's different from last year is that GlobalSign (the certificate creator) have changed from using SHA-1 to SHA-256 as their default.

Should i try to install the EV Cross Certificate in order to try the SHA-1 certificate instead of the SHA-256 option?

Any help is greatly appreciated.

Follow below steps

1) Import Certificate into IIS, Personal folder into same server where from you generated CSR.
2)IF you generated CSR from same server, Open EMC and select newly import certificate and click apply
3)If not, Please export the certificate in PFX format with Password and private key option checked.
4)Open IIS in Exchange server and Import certificate into IIS personal folder.
5)Open EMC in Exchange server and apply newly import certificate.
6)In additions to this, make sure intermediate certificate installed on Exchange server.

Even if i click Next / Browse and manually type certname.pfx it attaches the .cer on to the end and i don't get any option to export attached keys or certificates.

Remove .cer extension. just save the file in PFX format.

Attach screenshot for your reference.

But even if i remove the .cer extension in the Browse window it adds it again to the file on the next screen. The options to "Export Keys" and "Include all certificates in the certification path" are set to No and I can't change them.

When you initally imported the key using the pfx or cer file you need to specifically make sure that "allow private key to be exported" was checked. My guess it was probably "unchecked".

That being said you will need to find the original PFX file and make sure that "allow private key to be exported" is checked.

Take a look at the below link for additional details.

Hi all, the problem was that the original CSR hadn't been created from the server i question. I recreated it and got the certificate reissued by GlobalSign, installed the intermediate certificate through the MMC snap-in and the actual ssl cert through the exchange shell.

All is now well.....for another year anyway!!

Thanks for the help.

I thought i'd start at the beginning and this time it worked. I'd obviously done something wrong in the first place.
