Send Mail using MS Graph

Introduction

The WPO365 Microsoft Graph Mailer for WordPress configures your WordPress website to send emails using the Microsoft Graph API instead of – for example – SMTP. Sending WordPress emails using the Microsoft Graph API has become the only available alternative after Microsoft has disabled basic authentication (username and password) over the SMTP protocol.
