I configured emails using azure Modern authentication. On email address I specified email@example.com which I used to sign in to the azure application.
On reply address I specified firstname.lastname@example.org, still an account in office 365.
I tried to send email now using email@example.com but got the following error in Acumatica.
It seems I cannot send emails through the created application using any user.
Could I have left out any permissions, or what might be causing this?
Thank you all.
