Few questions here:
1. Does SERP support TLS or only SSL?
2. Does it work with Office365 email server now? I remember there were problems earlier and I cannot find if they have been fixed.
1. Yes
2. It works. Just that they have changed some security back in 2018 July, so now the field "From" in the email must be the actual email address that is verified on your Office365 account.
