Comment Outlook older than 2016 called STARTTLS "TLS" (Score 0) 54
This is a ridiculous way of conveying to the world that Outlook 2013 and earlier, which nobody on the planet should be using since it's long since been abandoned, call STARTTLS simply "TLS" or "SSL".
STARTTLS uses normal unencrypted ports, and opportunistically attempt to enable encryption.
There is absolutely nothing to see here.
