I’ve followed the instructions for setting up the Outlook 365 mailer integration and tried to redo it multiple times but keep getting this notice at the top:
———
EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.6.0 logged this error during the last time it tried to send an email:
Mailer: Outlook
InvalidAuthenticationToken: Access token is empty.
Date: 2021-02-24T19:42:35
Consider running an email test after fixing it.
