I’m installing an on-permise Exchange 2019 CU4 on Windows Server 2019.
I used win-acme.v188.8.131.520.x64.pluggable to create a certificate for all the necessary domain name, mail.mydomain.org, mail2.mydomain.org, autodiscover.mydomain.com…
It worked because now i have a correct certificate on IIS and correct certificate browsing from web but no certificate on exchange administration to be added as SMTP certificate. To be more clear, in Exchange control panel -> server -> certificate, i don’t see the certificate that win-acme create and i have no idea how to add it and apply it to SMTP traffic.
First noob question:
Are LE certificates suitable for a mail server to work as SMTP, IMAP certificate…? I read on the forum that LE it’s OK for mail server but I see guide and procedure just to add it as IIS certificate.
If this is possible, how to do it?
