Reporting and message trace in Exchange Online Protection

Microsoft Exchange Online Protection (EOP) offers many different reports that can help you determine the overall status and health of your organization. There are also tools to help you troubleshoot specific events (such as a message not arriving to its intended recipients), and auditing reports to aid with compliance requirements.

##Message trace

Follows email messages as they travel through EOP. You can determine if an email message was received, rejected, deferred, or delivered by the service. It also shows what actions were taken on the message before it reached its final status.

You can use this information to efficiently answer your user's questions, troubleshoot mail flow issues, validate policy changes, and alleviates the need to contact technical support for assistance.

Audit logging
