Is it no longer possible to suppress Security Alert prompt in Outlook 2019 for an Exchange Invalid Certificate name mismatch security alert via Registry? Using unsigned self-cert that doesn't match. I could suppress this with registry edits on 2013, but none of the entries I'm trying now seem to be working.
Outlook 2019.
Security Alert
The name on the security certificate is invalid or does not match the name of the site.

Hasn't been possible since 2016 as far as I know.
That sort of implementation kind of died off around when certificates became free with LetEncrypt and equivlents recommend you simply go that route on the Exchange side if at all possible.
