Question:
Please advise upon entering outgoing email configuration. When I press test SMPT setting this is an error I get.
Sending test email to '******'...
ERROR sending email:
5.2.252 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message
due to a permanent exception with message Cannot submit message
Answer:
This error is thrown by your SMTP server. Your SMTP server does not allow custom "from" addresses. Please either set the "from" to the value allowed or use our built-in SMTP server supplied by the SaaS helpdesk app.
Sometimes SMTP servers deny custom "from" names too. Under "Admin - Email" try enabling this setting: "Use 'From Name' for ALL outgoing notifications"
