Tagged: Office365, invalid_grant
So, nothing has changed in either our Office 365 setup or our WordPress setup but all of a sudden, emails attempting to go out are logging the error invalid_grant. I am using the application with the additional extension for Office 365. Is there a way to reconnect the API or reauth the API? I don’t see anything in the settings. I have gone through and re-run the setup but still get the same error.

Hi Jayson,
I hope you are doing well.
Seems like its a Microsoft Azure configuration issue, watch this video (https://www.youtube.com/watch?v=ze4mMraEvwQ&t=78s), reset the plugin, and configure it again and if the issue is still there then let me know.
Thanks
