Autodiscover and AutoSSL

Hello, So, i just yesterday tried to configure for the first time AutoDiscover&Autoconfig for my WHM Server. But i am unsure as to how deal with my first problem. I have AutoSSL installed, and i have parked a new domain on top of a domain which was set to reset to default server settings. But this one should have been on Disable to begin with. I Ticked it down to Disable before parking the domain. Anyway, the Autodiscover ends configuring my account using encryption using portt 995 and 465. I assume, that if my domain had never supported ssl/tls it would have used the unsecured ports. But where my concern is : When i set up a new account it supports SSL for a while then it dies unless i set in autossl the account on Enabled, my guess is it has something to do with a free certificate issued to new accounts. How do i make sure a new accounts never support SSL/TLS so my autoconfig correctly configures the first time the Outlook client of a user who opted out of encryption on my mail server? I want to know if ticking off this option completely prevents a mail client from connecting on secure ports using autoconfig : Tweak Settings -> Security -> Generate a self signed SSL certificate if a CA signed certificate is not available when setting up new domains Also, is there a way to cut immediatly the possibility for one account to connect their mail client through secure ports at all? Thank you.
