Rather than deleting an alert and creating a new alert, you can edit an alert to change the criteria for receiving emails or to change the email address(es) where Media portal sends the alert. You can edit alerts you created or alerts for access groups where you're the domain admin.
From the main menu, select Network Tools > Alerts.
Media portal shows the alerts you've set up for your profile (if any). To view alerts for all users in your access group, clear the Show Only My Alerts checkbox.
On the row for the alert you want to edit, click the plus sign () or the link in the Alert Name column.
Media portal shows details for the alert: conditions that trigger the alert, the email address the alert is sent to, when the alert was created and last modified, and whether the alert is enabled or disabled.
Click Edit Alert.
Make your changes to the alert. When you're done, click Save.
