Exchange 2019 ssl certificate invalid

New Contributor

I have installed Exchange 2019 for testing purposes. I have purchased a domain name and a certificate. After I installed it, the status shows: invalid. Thank you.

@belilan,

 From your picture, it looks like your CSR might not have been correct, or your certificate wasn't correctly installed, as I do not see your Exchange Virtual Directory URL under the name (Figure A).

 

I understand the steps you have taken; you purchase a domain; let say for this example, it is contoso.com, and your exchange server virtual directory URLs are exchange.contoso.com. You created a Certificate Sign Request (CSR) for exchange.contoso.com and submitted that request to a certificate authority. Once you received your certificate, your complete a pending certificate request. Which then, you are assign services to that certificate.

Hi.

I had to add the CA_bundle.crt in the trusted....

It works fine now.
