Handling Notification Failures
If Vector HelpDesk is unable to send a notification, it tries to resend the notification. By default, the maximum number of retries is 100. When the maximum number of retries is reached, the notification is sent to the e-mail address specified by the Send Invalid Notifications To option.
To change the Maximum Notification Retries option or the Send Invalid Notifications To option, click Tools>Options in HelpDesk Admin.
