SharePoint Notifications for Terminated Employee

I understand the issue with SharePoint notifications continuing to be sent to a terminated employee's email address. To address this, you can start by deleting alerts for the terminated employee by going to Site Settings > Site Administration > User Alerts, selecting the user, updating, and then deleting the selected alerts. Additionally, consider managing permissions to prevent similar issues in the future by creating a custom permission level that removes the ability to create alerts for certain users or groups. Regularly reviewing and updating notifications can also help ensure they are relevant and not causing unnecessary issues.
