So, yes you can set any windows device to operate as an SMTP relay. Server versions have this capability built in. You enable it in the features section of Server manager. You can then configure the local side to be an open relay not requiring auth or encryption, and configure the public side to do all the auth and encryption.
Alternatively, and depending on the Office365 receive connectors configuration, you *should* be able to use the endpoint connector. Assuming my mail domain is slylabs.com, my endpoint connector would be slylabs-com.mail.protection.outlook.com. That system is in place precicely because Microsoft recognizes there are devices and applications that cannot use encryption, or have not or cannot be updated to the TLS 1.2 standard.
