How to setup email notifciations

Hi there,

 So I'm new to this program and looking a way to have email notifications from Essentials to our mailbox we use in IT. Ideally I would like to use the localhost sent to my email and our IT email but every configuration. I setup the local SNMP relay on the host server, but when I try and run the test it says failed almost 10 minutes later.

Are there any instructions available to do a proper setup? Please note that we are using O365. Maybe that has something to do with the difficulties. I was hoping to have it sent from localhost to my address so it doesn't go out to come back in.
