On PowerVault ME4 when email alerts are configured choosing TLS Security Protocol using port 587, they may fail to send. For example: When using smtp.office365.com as an SMTP server to sending email notification from a PowerVault ME4 array. After configuring SMTP Server, Sender Domain, Sender Name, using Port 587 with Security Protocol TLS. Email notification fails to reach the destination Email address. In the ME4 event log, Event 6 11: "Email notification failed due to improper configuration. Please verify the sender, sender-password, domain parameters, and server settings" is reported. As documented in Microsoft Documents, in How to set up SMTP AUTH client submission the following settings will enable you to send email from your device or application. Device or Application setting Value Server/smart host smtp.office365.com Port Port 587 (recommended) or port 25 TLS/StartTLS Enabled Username/email address and password Enter the sign in credentials of the hosted mailbox being used Requirements for SMTP AUTH client submission Authentication : You must be able to configure a username and password to send email on the device. You cannot use Microsoft Security Defaults or multi-factor authentication (MFA), which disable basic authentication and are designed to protect your users from compromise. If your environment uses Microsoft Security Defaults or MFA, Microsoft recommend using Option 2 or 3 as documented in Microsoft How to Setup SMTP document . Mailbox : You must have a licensed Microsoft 365 or Office 365 mailbox to send email from. Transport Layer Security (TLS) : Your device must be able to use TLS version 1.2 and above. Port : Port 587 (recommended) or port 25 is required and must be unblocked on your network. Some network firewalls or ISPs block ports, especially port 25. DNS : You must use the DNS name smtp.office365.com. Do not use an IP address for the Microsoft 365 or Office 365 server, as IP Addresses are not supported. NOTE: SMTP sender password fields accept the only alphanumeric characters and ^ _ + : , . @. And also the sender password can have a maximum of 32 bytes. So they system won't accept password including "$" or any other symbols other than ^ _ + : , . @.
