O365 API to send mails from local server to Office 365

[Marvin Oco]

is there a way to implement API connection from local servers to o365 which enables the server to send email instead of using smtp relay?

is there any reports or dashboard in place that can monitor the success or fail of every email sent.

The best way to do this is through the Graph API
Docs: https://docs.microsoft.com/en-us/graph/api/user-sendmail?view=graph-rest-1.0&tabs=http

For these failures, there isn't a general dashboard as far as I know
