The message trace feature enables you as an administrator to follow email messages as they pass through your Exchange Online or Exchange Online Protection service. It helps you determine whether a targeted email message was received, rejected, deferred, or delivered by the service within the past 7 days. It also shows what actions have occurred to the message before reaching its final status. Obtaining 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.
|For troubleshooting general issues and trends, use the reports in the Office 365 admin center or the Excel reporting workbook to obtain such data. For single point specifics where details are needed about a message, use the message trace tool. If a message is delivered to a mailbox, the delivery reports feature can give Exchange Online customers additional information, for example about inbox rules and getting the overall picture of the delivery status for a distribution list; for more information, see Track Messages with Delivery Reports.|
