Problems Configuring NSM SMTP Notifications

I'm running NSM 2.3.0-R9-8c0195ea and am having problems configuring system notifications via SMTP. I need to use an MS Office 365 authenticated account to send the email. I'm using this same account to send email from SonicWALL firewalls, so I know the account credentials are good and TLS Authentication (which is required) is working with O365.

Under SYSTEM -> Settings -> Administration -> Notifications, I set

  • Mail Server: smtp.office365.com (I've verified that NSM can ping this DNS name in Diagnostics)
  • From Email Address: [email protected]
  • Advanced Settings toggled on
  • SMTP Port: 587
  • Connection Security Method: SSL/TLS
  • Enable SMTP Authentication toggled on
  • Username: [email protected]
  • Password: password-for-user

I need notifications so I can set up Two Factor Authentication for users. When I log in as a user and try to send E-MAIL for the Two Factor Authentication, I get a pop-up message saying "Internal server error"

When I go to Logs and Alerts -> Events, I see the following error message:


I don't see much further useful information if I turn on debug logging. How can I troubleshoot this further? Is there anyone out there using MS O365 for email notifications?
