Migration of Service account SMTP AUTH services (email relay) from Office 365 to Proofpoint SER (Secure Email Relay).

Question

I have a Service account used for sending emails from Azure Services (Automation Account or Azure Functions). When it was created it is using Office 365 enabled Service Account for sending alert mails, now we have to migrate SMTP AUTH services (email relay) from Office 365 to Proofpoint SER (Secure Email Relay). 

My Question is what are the changes that I need to do from IAC Perspective. Like the values of smtp server, Credentials & Port?

    "smtpServer" : {
      "value" : "smtp.office365.com"
					}

Answer 1

You will prob need to contact Proofpoint Support for that info if this isnt valid:
