For the longest time I've had a clients NAS setup with email notifications from their O365 tenant. Settings were as follows

SMTP Server Address:smtp.office365.com
SMTP Port:587
Sender Address:it@xxxx.ca (where xxxx is their domain in O365)
Authentication Type: Login (SMTP-AUTH)
SSL/TLS:STARTTLS
Username:it@xxxx.ca
Password:******************

Password hasn't changed, and I can login to Office.com with the account. In the O365 admin, SMTP Authentication is enabled for this specific user as Modern Authentication is enabled for the Org settings.

I have other scan to email devices setup with an existing O365 connector and I have replicated the settings on the NAS, but those test emails fail as well. Settings are:

SMTP Server Address:xxxx-ca.mail.protection.outlook.com
SMTP Port:25
Sender Address:it@xxxx.ca
Authentication Type:Disabled
POP3 Server Address:Not configured
POP3 Port:110
SSL/TLS:STARTTLS
Username:it@xxxx.ca
Password:******************

From what I see on the web interface it seems like when I disable SMTP auth it's also disabling the SSL/TLS settings, which are required for sending through a connector.

As a test I used the settings for the O365 direct send option. Which doesn't require smtp authentication, or SSL/TLS settings. The only restriction is it can only send email to addresses within your O365 tenant. This worked, and I had to forward email from that account to my email address.

It does appear as though disabling SMTP Auth also disabled SSL/TLS settings, or it's not using TLS 1.2. This should be fixed!

But it begs to ask why I can't send email via SMTP Auth, or by using the existing O365 connector that it setup for the existing multifunction printers?? Does the Terrastation not support TLS 1.2?

What model device is this?
