Microsoft Office 365's mail flow trace tool

Microsoft’s, Office 365 might be great, but just like every new born baby, it needs further development and improvement.
For example, currently it is possible that an e-mail does not get delivered, and a bounce back e-mail is not generated.
Microsoft are developing a mail flow trace tool but it is not fully deployed just yet, and it currently allows us to only trace e-mails for the last 7 days. When the feature is available to the public, it will allow you to trace messages sent up to the previous 90 days.
This will be a great e-mail troubleshooting tool that will allow you to specify data range, with specific times, sender and recipient e-mail addresses and some other adjustments to your searches.
Here is what the official text on the web page says, “Requests for messages older than 7 days are provided as downloads. Messages older than 90 days are unavailable.” However, Microsoft has advised to not rely on it too much, just yet.
The tool can be accessed by:

  1. Login to your webmail in Office 365 as an administrator.
  2. Click on Outlook.
  3. Edit the URL in your browser from to  and press return on your keyboard.
  4. On the left side of the web page, there is a mail flow option, so click on that.
  5. The message trace tab can be accessed when the mail flow page loads as well as a few other useful tools.

When the trace request is submitted, there will be a View pending or completed traces link available on the same page that will allows you to view the status of your traces.
