Here's two methods to send SMTP notifications from Events2HVAC when you are using Exchange/Office365.

Refer to this MS Office document for all the details of these along with other options.
How to set up a multifunction device or application to send email using Office 365

Option 1

This option requires the from address in E2H to have an exchange mailbox and login.

From Address: events2hvac@yourdomain.com
SMTP Server: smtp.office365.com
SMTP Port: 587, Use TLS checked.
SMTP Username: events2hvac@yourdomain.com
SMTP Password: {password}

Note: Option 1 uses Authenticated SMTP which is blocked by default for Office 365.  To change this, you have to Disable security defaults then enable SMTP for the user (see below).

After disabling security defaults, visit the Microsoft 365 admin center, go to Active Users, click the user you are using for SMTP, then click the Mail tab, click Manage email apps, check the box for "Authenticated SMTP", then click "Save changes".  Note that it can take a few hours for these changes to take place.
