I do not believe any company, much less Microsoft, is going to sent
emails from their users to other users through your mail server.
But they do. As the OP says, they support an outbound "smarthost"
connector, it is just missing an authentication functionality.
This is not such an unusual requirement. I have worked with multiple
businesses whose regulatory compliance relies on having all external
communication archived in real time to a 3rd party system. This allows
users to manage their mailboxes however they like without risking
violation of company policy or law. Often a 'global Bcc' is adequate for
that but it can be a better fit to put redirection a step away from the
mail system handling mailboxes.
