I need to know does Office365 allow to send bulk email from Powershell. I have tried Powershell script but no avail.
I have got below errors in Powershell after running the script;
Sending Notification to (email@example.com)
Exception calling "Send" with "1" argument(s): "Error in processing. The server response was: 5.7.3 STARTTLS is
required to send mail [PM4QW0902CA0020.usprd09.prod.outlook.com]"
Any help please.
