A Message Trace can be used to trace emails through Exchange Online, based on defined criteria (for example: email address, date range, delivery status, or message ID). To generate an Office 365 extended message trace, follow steps below:
- Browse to https://protection.office.com/messagetrace
- Sign in to Office 365 with your admin account
- Specify a sender (or a message ID under "More search options")
Note: If you have the Message ID (which can be found in the message header) this is the best option - only one message will be found when using the Message ID. Alternatively you can add the sender or recipient, and select the message direction inbound/outbound. - Set an appropriate date range for the message you need to trace
- Specify the report type Extended report:
- Click Next
- Specify a title and an email address for a notification message to be sent to when the trace is complete.
Note: Extended traces can sometimes take several hours to complete. You can check progress at any time from the "Downloadable reports" section on the Message Trace home page.
