Your site is proxied so you will only see Cloudflare’s edge certificate when you connect to your web site. The certificate on your origin server will only be seen by Cloudflare’s proxy connecting to your origin.
If you want to see your origin certificate, pause Cloudflare or set the DNS record to “DNS only” briefly to see it, but set it back to being proxied to ensure Cloudflare protects your site.
The thing is that the cloudflare certificate does not appear when I want to see more details of the connection, in addition to that in Outlook when they open the program it tells them that the certificate is not valid, I enter the domain and I get that the connection is not secure :(, As for the SPF, thank you very much, I already eliminated it
Cloudflare does not proxy mail connections, so that Outlook is getting a certificate at all means that certificate isn’t coming through Cloudflare and is something you need to confirm with your mail provider.
As I said, your site is proxied so you will see the Cloudflare edge certificate (from LetsEncrypt) when visiting your website. The only ways to see the origin certificate in your browser is to connect to the origin directly, or pause Cloudflare or set the DNS record to “DNS only”.
Read this to understand what is happening…
If your mail client is connecting to inladsac.com then that’s your mail problem. Outlook needs to connect to mail.inladsac.com (assuming it has been set with the correct IP address) as Cloudflare cannot proxy mail traffic (unless using the Spectrum product).
Outlook is connecting to mail.inladsac.com, as you can see in this image it tells me that the certificate is not valid, but I don’t know why since as you can see in the previous images I specified that domain mail.inladsac.com
