If that is inside Microsoft, you can't use private IP addresses. If you don't want to use a Certificate, I believe you have to create it as localhost. I have never used Email to create tickets, but I have seen some other people say that.

Daedalus01 is correct. Unfortunately, MS requires you to use HTTPS with the exception being localhost for HTTP.

Same thing applies for Google. Here is the OAuth2 documentation for Google emails:

As I mentioned above you must use HTTPS; if you are required to use HTTP then you have to use localhost.

It’s smtp.office365.com port 587.
