Monitoring, reporting, and message tracing in Exchange Online
Exchange Online 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. The following table describes the reports and troubleshooting tools that are available to Exchange Online administrators.

|Message trace||Follows email messages as they travel through your Exchange Online organization. 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.
