Microsoft Exchange Online includes a very robust, cloud-based suspicious email filtering service, Exchange Online Protection (EOP), which protects WCM-Q against spam and malware. Such suspicious emails will be sent to your Junk folder immediately, from where you can release them if required, without having to wait for a spam notification.
To release an email from the Junk Email folder:
- In Mail, click on the Junk folder in the Navigation Pane.
- In the message list, right-click on the message you want to mark as not junk
- From the Junk Mail menu item, click on Mark as Not Junk.
