After you click the Run Checks button to submit your checks, the Troubleshooting Tools page displays a blue-shaded rectangle that shows the prompts and responses that comprise your check, separated by plus signs, and followed by buttons marked Modify and Clear Form.
Further down the page, a progress bar is displayed while the checks run. When the checks are complete, the page displays information on two tabs: Your Next Steps and Full Check Results.
Click Modify to return to the previous page with your selections intact so that you can modify the selections. Click Clear Form to return to the previous page with your selections removed and specify new selections.
Your Next Steps
This tab displays information about the severity of the problem, along with a description of what's wrong and of the steps to take to resolve it. Because a failure to deliver or receive email often results from multiple factors, the Next Steps list usually contains several items rather than a single listing. This tab also often contains information about checks that resulted in success rather than failure (marked with a green checkmark icon, a yellow caution icon, or a black information icon in the Severity column). These are provided for your information, and do not require action.
In contrast, issues marked with a red X icon in the Severity column must be resolved in order to solve your delivery problem. Read the description of the issue in the Problem column and then follow the steps in the Resolution column.
Full Check Results
This tab displays the results of all of the checks performed by the Email Delivery Troubleshooting Tool. This tab is divided into three areas:
Check result, which displays an icon that indicates the status of the check (Fail, Warning, Information, or Pass). Pass means all is well, and Fail means that action must be taken to restore normal email delivery. Warning triangles indicate areas in which further investigation is probably necessary, and Information entries often describe how to perform further analysis.
Problem Area, which displays the part of the network that is having the problem.
Check, which describes the condition, situation, or physical component of the network that was checked.
When you click on a row in the Full Check Results display, a Details panel appears. The Details panel displays further information about the results of the check described in that row.
This information can be used to understand the larger context of the issue you are troubleshooting, and to resolve related issues so that they don't cause further mail delivery problems in the future.
