For those who are using Office 365 (E1, E3, E5 and Advanced ATP), a interesting update is coming on Office 365 Security & Compliance center: alert policies

As a first stage deployment, these new default alerts will let you when:

  • an elevation of privileges has been done on Exchange Online
  • emails are being delayed for delivery
  • a user is creating a forward/redirect rule

To take advantage and configure these alert go to your Security & Compliance center and reach the Alerts\Alert Policies configuration blade

Then by selecting one of the rule you will be able to edit it to define if the notification is enabled or not (default is: ON), who is receiving it (default is Tenant admins)
