WPO365 | MICROSOFT 365 GRAPH MAILER for WordPress

WPO365 | MS GRAPH MAILER provides you with a modern, reliable and efficient way to send WordPress transactional emails from one of your Microsoft 365 / Exchange Online / Mail enabled accounts.

The plugin re-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.

DELIVERY

Send WordPress transactional emails from one of your Microsoft 365 Exchange Online / Mail enabled accounts using Microsoft Graph instead of – for example – SMTP.

Or: Select either a Microsoft 365 account or a personal Microsoft account, like Hotmail.com or Outlook.com, to send WordPress emails.

Or: Configure RBAC for Exchange Online and authorize as an application but with a limited scope e.g. one specific mailbox.
