Exchange Online Protection  

Exchange Online Protection (EOP) is the cloud-based filtering service that protects your organization against spam, malware, and other email threats. EOP is included in all Microsoft 365 organizations with Exchange Online mailboxes. 

How EOP works

To understand how EOP works, it helps to see how it processes incoming email: 

·     When an incoming message enters EOP, it initially passes through connection filtering, which checks the sender's reputation. Most spam is stopped at this point and rejected by EOP.

·     Then the message is inspected for malware. If malware is found in the message or a message attachment, the message is delivered to quarantine. By default, only admins can view and interact with malware quarantined messages. But, admins can create and use quarantine policies to specify what users are allowed to do to quarantined messages.

·     The message continues through policy filtering, where it's evaluated against any mail flow rules (also known as transport rules) that you've created. For example, a rule can send a notification to a manager when a message arrives from a specific sender.

·     In on-premises organization with Exchange Enterprise CAL with Services licenses, Microsoft Purview Data Loss Prevention (DLP) checks in EOP also happen at this point.

·     The message passes through content filtering (anti-spam and anti-spoofing) where harmful messages are identified as spam, high confidence spam, phishing, high confidence phishing, or bulk (anti-spam policies) or spoofing (spoof settings in anti-phishing policies). You can configure the action to take on the message based on the filtering verdict (quarantine, move to the Junk Email folder, etc.), and what users can do to the quarantined messages using quarantine policies.

A message that successfully passes all of these protection layers is delivered to the recipients.
