  • Super good mail plugin

    I really appreciate author's contribution. I installed this plugin and it has been working great! Now I have upgraded my WordPress to version 6.0. This plugin is still working as usual. Can't imagine it is free.

  • It works and is not difficult to configure

    Very nice plugin. Highly recommended. Create the app on O365. Take record of the client ID, secret, Tenant ID. Put them all into the plugin. Authorize. Then everything works fine. The plugin does not offer sending test email feature. But you can go into the WordPress user page and manually send email to a user. I successfully sent an email to a test user on the first attempt after configuration.

  • Does not work with multisite environment

    Plugin works great, except in a multisite environment.

  • Perfect!

    Started looking in to how to do this myself and then I found this plugin. No issues at all and free!

  • Amazing

    I can't believe this is free! I got it to work with godaddy's managed wordpress. GoDaddy only issues O365 email accounts now. The instructions are very clear for such a complicated Microsoft process. Thanks to the author. I am so appreciative and relieved that it works.
