title: Can Office365 shared mailbox use SMTP?
body: <p>Need to set up service account on company printer, that sends print counters to copy company. So they can send us back the invoice.</p>
  
  <p>I was told, that this could be handled by shared mailbox without any licence. But it seems to me, that shared mailbox crendentials can not auth with SMTP.</p>
  
  <p>Do I need to buy licence? If so, which one?</p>
