Trace an Email Message

Exchange 2013
 

Applies to: Exchange Online Protection, Exchange Online

Topic Last Modified: 2014-01-30

Sometimes an email message gets lost in transit, or it can take a lot longer than expected for delivery, and your users can wonder what happened. As an administrator, you can use the message trace feature to follow messages as they pass through your Exchange Online or Exchange Online Protection service. With message tracing, you can determine whether a targeted email message was received, rejected, deferred, or delivered by the service. It also shows what events have occurred to the message before reaching its final status. Getting detailed information about a specific message lets you efficiently answer your user’s questions, troubleshoot mail flow issues, validate policy changes, and alleviates the need to contact technical support for assistance.

TipTip:
For troubleshooting general issues and trends, use the reports in the Office 365 admin center or the Excel reporting workbook. For single point specifics where details are needed about a message, use the message trace tool.
