WP SMTP Plugin error [Microsoft Outlook]

Replies: 0

Hi guys,

I am currently getting this error on my SMTP plugin. I have deployed the settings using Microsoft Azure. When I remove the connection for authorisation, the error goes away but after an hour or so, it again gives me the authentication token error. The error is mentioned below:

Heads up! The last email your site attempted to send was unsuccessful.

Email Source: WPForms
Mailer: 365 / Outlook
InvalidAuthenticationToken: Access token has expired or is not yet valid.
