Good morning,
I have connected a shared mailbox within Business Central, it seems to send test emails fine. When we try and send an email to a customer (with invoice attached) the below error is received:
Could not get access token. Please, try to log out and log in again.
Has anyone come across this error and knows of a way to fix? It was working fine, but has suddenly stopped working with no change. All users have 'send as' permission in exchange and are members of the shared mailbox.
Regards,
Matt
