Reporting and message trace in EOP

Important

Welcome to Microsoft Defender for Office 365, the new name for Office 365 Advanced Threat Protection. Read more about this and other updates here. We'll be updating names in products and in the docs in the near future.

In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, 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.

Usage reports

Custom reports using Microsoft Graph

Programmatically create reports that are available in the admin center by using Microsoft Graph. For more information, see Overview of Microsoft Graph and Working with Office 365 usage reports in Microsoft Graph.

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.

See Message trace in the Security & Compliance Center.

Audit logging

Tracks specific changes made by admins to your organization. These reports can help you troubleshoot configuration issues or find the cause of security or compliance-related problems. See Auditing reports in EOP.

Reporting and message trace data availability and latency

The following table describes when EOP reporting and message trace data is available and for how long.


Report type Data available for (look back period) Latency
Mail protection summary reports 90 days Message data aggregation is mostly complete within 24-48 hours. Some minor incremental aggregated changes may occur for up to 5 days.
Mail protection detail reports 90 days For detail data that's less than 7 days old, data should appear within 24 hours but may not be complete until 48 hours. Some minor incremental changes may occur for up to 5 days.

To view detail reports for messages that are greater than 7 days old, results may take up to a few hours.
Message trace data 90 days When you run a message trace for messages that are less than 7 days old, the messages should appear within 5-30 minutes.

When you run a message trace for messages that are greater than 7 days old, results may take up to a few hours.

Note

Data availability and latency is the same whether requested via the admin center or remote PowerShell.
