The Email Activity/Protection Layer
Incoming and outgoing emails can be tracked and delivery failures promptly captured using the tests mapped to this layer. The tests also proactively alert administrators to non-availability of Exchange Online for sending/receiving mails and slowness in mail delivery. Additionally, the tests also turn on the spotlight on spam mails, malware, and DLP violations, thereby revealing to administrators how well-insulated user mailboxes are from malicious attacks. Transport rules and mails that conform to those rules are also highlighted by the tests, so as to enable review and reconfiguration (if required) of rules.
