I have 2 exchange servers run for one email service, and I need to renew the SSL certificate. Do I need to issue 2 SSL, or one is enough? If one is enough how can I replicate it between them?

    Why exactly do you have 2 certificates today? – Ramhound May 04 '22 at 16:37
  • I did not have 2 certificates , I have 2 servers. I'm asking about how to install the certificates on both servers – Ali Muhanad May 04 '22 at 18:55

    How did you install the current TLS certificate being used. If you don't have 2 TLS certificates today, then you have answered your question, if the same certificate can be used on 2 servers. – Ramhound May 04 '22 at 21:13
  • Actually another guy installed the old one, – Ali Muhanad May 05 '22 at 19:52
  • How you install the certificate will vary based on the specifics of your infrastructure. – Ramhound May 05 '22 at 19:55
  • Thanks a lot for your assist, In the first server, I have created the request, then I got "complete" button, then I press the "complete" and point to the .cer file, I think its done. now in the second server, when I press the 3 dots button and chose import, I got this error "A special Rpc error occurs on server EX2: Cannot import certificate. A certificate with the thumbprint ............... already exists." – Ali Muhanad May 07 '22 at 12:03
