I'm running a Dell PowerEdge T440 with iDRAC9 Enterprise. I'm attempting to setup SMTP alerts using Office 365. I have been unable to successfully send a test e-mail at all. I receive the error: **`RAC0225`** every single time I sent a test e-mail.

This is the setup so far, any help would be super appreciated because I'm at a loss.

**iDRAC Settings** -> Connectivity -> Network -> Common Settings
Register iDRAC on DNS: Enabled
DNS iDRAC Name: iDRAC-ServiceTag
Auto Config Domain Name: Disabled
Static DNS Domain Name: xxx.userdomain.com
Connection View: Enabled

**Configuration** - > System Settings -> Alert Configuration
Alerts: Enabled

**Configuration** -> System Settings -> SMTP (Email) Configuration
Email Alert 1: my.email@emailaddress.com

**Configuration** -> System Settings -> SMTP (Email) Server Settings
I've attempted various configuration settings in this area such as:
SMTP (Email) Server IP Address or FQDN /DNS Name:
Public WAN IP
domain-com.mail.protection.outlook.com. 
I created an IIS Server with SMTP enabled and followed this guide: <http://www.ponjavic.com/wordpress/2016/06/16/configure-smtp-relay-server-for-office-365/> for the setup

I'm complete at a loss of how to set it up. Even if I'm not able to, or it's an extremely small oversight I missed I just want to know if it's possible, and how people have had luck setting it up because I haven't had any.

Thank you so much.
