Hello,

I have a WildCard SSL Certificate (*.domain.com) and two freshly installed Server, one with Microsoft Exchange Server 2010 and another with Microsoft Exchange Server 2013.

I got Certificate in (.crt) format from Third-Party SSL Vendor.

When I try to import in Exchange Server 2010, it asks me for (.pfx). But when I open Certificate and try to "Copy to File..." , I get only (.cer) and (.P7B). How can I get (.pfx) out of it? I don't have any private key with me.

What I have is the CSR (.req) through which I ordered the (.crt).

When I try to import in Exchange Server 2013, at first it doesn't shows up and when I try again it says "already exists".

Have same issue with IIS, so due to that I am unable to setup ADFS too.

Please provide me the best solution.

Thanks,

This means that your certificate does not have private key associated on machine, or private key export was disabled by your certificate vendor. You must have private key present to use certificate with Exchange server. I suggest that you contact your certificate vendor and ask them to re-issue the certificate with private key.
