WPO365 | MICROSOFT 365 GRAPH MAILER

I have tried different solutions on different times. But this plugin really works and so much simpler settings. Really good plugin with detailed and easy to follow documentation. 

Thank you so much for this lovely plugin, Marco!

Wow 🤩 it works!!!


Nice plugin to send easy e-mails. Easy to install


WPO 365


Perfect. Now I don't have to worry about this for another 2 years when the password expires 😂 I have created a calendar entry but I wonder if Microsoft will send an email before expiration 🤔



Anyway, thanks a lot!


Just what I needed!

Send WordPress emails from a M365 / Exchange Online Mailbox using Microsoft Graph, leveraging OAuth for authentication which is more secure than SMTP
