Create a new message trace
You might find that you need a message trace when a user contacts you about messages that are not delivered or are taking longer than usual to be delivered. You can trace a message using various criteria, including email address, date range, delivery status, and message ID.
In the EAC, press Ctrl+F6 until the primary navigation pane has the focus and you hear "Dashboard, Primary navigation link."
Tab to mail flow, and press Enter.
To move to the menu bar, press Ctrl+F6.
Tab to message trace. You hear "Message trace, Secondary navigation link." Press Enter.
To access the main window list view, press Ctrl+F6. You hear "Message was sent or received combo box, Past 48 hours."
The Date range combo box has the focus, and the default setting is Past 48 hours. To cycle through the other choices, including Past 24 hours, Past 7 Days, and Custom, press the Up Arrow or Down Arrow key.
Tip
If you select Custom, you can tab to and enter the time zone, start date and time, and end date and time. These fields are not available unless you select Custom in the Date range combo box. Note that there might not be any data for messages that are less than four hours old. You cannot run a message trace on a message more than 90 days old.
Tab to the Delivery status combo box. Choices are All (the default setting), Delivered, Failed, Pending, Expanded, Quarantined, Filtered as spam, and Unknown. Press the Down Arrow or Up Arrow key until the delivery status you want is selected.
Tab to the Message ID text box. This is an optional field, but it can help narrow the search results. The Message ID or Client ID is generated by the sending system and can be found in the header of the message with the Message-ID: token. The Message ID might include angle brackets (< >).
To specify senders (one or more) in the message trace, tab to the add sender button and press Enter. In the Select Members dialog box, the Search button has the focus.
To search for a user within your organization, press Enter, type all or part of the name of the user, and then press Enter.
Press the Tab key about seven times until you hear the name of the user in the search results list.
To add the user to the list of senders for the message trace, press the Down Arrow key until you hear the user's name and then press Enter. The list of users retains the focus, so you can continue to add more users by selecting their mailboxes and pressing Enter.
Tip
To check the users you've added, tab to the Add button. To hear the list of users, press the Tab key again. The first name is read. To hear the second name in the list, press the Tab key one more time. Continue pressing the Tab key until you hear the names of all the users you've added. To delete a user from the list, activate the Remove link by pressing Enter when you hear the username.
- To specify an external user or an email address with a wildcard (for example, *@contoso.com), press the Tab key until you hear "Check names edit, Type in text." (In Narrator, you hear "Editing.") Type the email address of the external user or the address with a wildcard. To select the Check names button, press Shift+Tab and then press Enter. This verifies the email address and adds it to the list of users.
Tip
When you specify a wildcard, you cannot also add full email addresses to the message trace. > Be aware that if you type an external email address and press Enter, this adds the user to the list and then closes the dialog box. If you're not finished, use the Check names button to add it instead.
- When you finish adding users, tab to the OK button and press Enter. The message trace page has the focus again, and the Sender text box lists the senders you specified for the message trace.
To add a recipient to the message trace instead of or in addition to the senders, tab to the add recipient button and press Enter. In the Select Members dialog box, the Search button has the focus. To add one or more recipients to the message trace, repeat step 9.
On the message trace page, tab to the search button and press Enter. The Message Trace Results page opens and shows the date, sender, recipient, subject, and status of the message(s) that are a result of the message trace.
Tip
When you run a trace for messages that are less than seven days old, the messages should appear within 5-30 minutes. When you run a message trace for messages that are more than seven days old, results may take up to a few hours. So if the Message Trace Results page appears empty at first, check again later. An easy way to do this is to keep this page open, and, on the toolbar, periodically tab to the Refresh button and then press Enter.
