Question Let's Encrypt not securing web mail subdomain - Plesk Onyx Windwos

[kaiyaq]

I'm new to Plesk, running Onyx on Windows. My "webmail.domain.com" was secured using Let's Encrypt certificate but after 3 months it failed to renew automatically.

I manually renewed the certificate on the main domain which worked, but not for "webmail.domain.com"

I've tried renewing multiple times and securing web mail manually but I cannot get it to work. I tried removing the main SSL certificate on the domain but Plesk is not allowing me to do that either.

I'm using Mail Enable. How can I correct this?

Do I need to create the "webmail.domain.com" subdomain manually and secure it using Let's Encrypt?

Managed to work out why "webmail.domain.com" was not being secured, it was because I was using Mail Enable. I installed Horde and an option for securing web mail on the LE SSL Certificate screen became available, that did the trick.
