Notification emails have broken links
The notification emails have a "View the problem" link that goes to the home page. It should go to the problem in the email. Otherwise there is no way to get to the problem referenced in the email, and typically there is not enough information in the email to find the problem any other way.
This bug should be fixed it. Try it out in the latest release. If you’re still having problems, please file a bug through the Report a Problem in Visual Studio 2017.
