The email notifications is not being sent. I am getting 2 kinds of errors:
- Message failed: 550 5.7.60 SMTP; Client does not have permissions to send as this sender MWHPR08MB3582.namprd08.prod.outlook.com
- timeout calling smtp
My smtp host is smtp.office365.com and port 587. I provided the correct username and password. What could be causing the failed sending of messages?
