Why don’t I receive any alerts when a user submits a request to a Help Desk that I am a technician of?

A: Two possible reasons, the first possible reason is that the Help Desk Owner did not select you as a technician to alert when configuring the Submit Help Desk Requests island. See the Configuring the Submit Help Desk Requests Island section of the Help Desk guide for more details. 

The second possible reason is that your personal alert settings may not be turned on for the help desk module. Make sure to check My Settings > My Preferences to ensure that the help desk alerts are turned on for your profile.
